    Sea Defence. Which is better: hard or soft engineering?

    4 star(s)

    This type of hard engineering is good as it has many aspects and is effective. Disadvantages of creating a sea wall are that it is very expensive to build; the curves in the sea wall reflect the wave's energy back to into the sea, therefore the waves remain powerful. Another disadvantage is that the walls erode after time and the cost of maintenance is high. Another example of hard engineering is groyne, a groyne is a wooden barrier built at a right angle to the beach.

    Earthquakes in MEDC's and LEDC's

    4 star(s)

    A major factor in the severity of the earthquake was the poor construction - a salient feature of LEDC's. The Indian Plate which was moving 40 mm a year north collided with the Eurasian plate and was forced beneath it. It measured 7.6 on the Richter Scale. As is evident, although the magnitude of both earthquakes was extremely similar, the impacts varied greatly. This was due to many factors, which most if not all are related to the economic situation of the countries. We shall begin by discussing the impacts of each of the earthquakes, thereafter we shall discuss why these effects differed.

    Why did so many people die in the Kobe Earthquake?

    4 star(s)

    This means there is very little flat land other than at the base of the volcanoes. Due to this, it is very crowded and congested. Believe it or not the population Of Japan is 124 million! That's approximately twice as much as England! There are also approximately 310 people per square kilometer. Also, there are some human causes of the Kobe Earthquake. We all know that, this present day, Japan is the most technologically advanced country in the world. But that means they must have run millions of tests and tried out new experiments and procedures to get to where they are today.

Therefore studying the history and the rivers we have Aid to bring about the prevention of floods. However, the study of rivers in the summer is different than in the winter because the river depth varies depending more rain in winter than in summer. This will also affect other functions of the river e.g.

    The River Mersey due to human activity). This will also increase lateral erosion as the water will be moving faster and carrying more load. As a result, the width increases. This hypothesis corresponds with the Bradshaw Model because fig.1 shows the width of the river increasing with distance downstream. Hypothesis 2 - The Depth of the River Increases with Distance Downstream This hypothesis was proved correct because figure two shows that the average depth of the river significantly increases with distance downstream.

    Why is Antarctica so important?

    3 star(s)

    Antarctica may hold the key to understanding food chains, and the role of plankton in those chains. It is possible that these small organisms form the base of the ecosystems that support all living things. The continent of Antarctica is also important because it is thought to have large deposits of valuable mineral resources including platinum, gold and silver. Coal in commercially attractive deposits has been found, but no other minerals are known to exist in potentially useful amounts. Large deposits of oil and natural gas are believed to exist in Antarctica's continental shelf. In understanding global change the Antarctic has a crucial role to play.

    Can We Win The Race Against Desertification?

    However, due to overgrazing, over cultivation and a lot deforestation, more dry land areas are under threat of desertification, which is why we need to prevent this. How can we prevent it? * Planting trees- this reduces soil erosion, sand movement and traps soil moisture and to keep nutrient levels high in soil. We should do this because one of the main causes of desertification is unabated cutting of trees and planted. When this happens, the surface of the soil becomes dry and the top soil gets blown away by wind or washed away by floods and rainwater.

    Marine Pollution

    5 star(s)

    Pollution from ships Ships can pollute waterways and oceans in many ways. Oil spills can have devastating effects. While being toxic to marine life, polycyclic aromatic hydrocarbons (PAHs), the components in crude oil, are very difficult to clean up, and last for years in the sediment and marine environment. Discharge of cargo residues from bulk carriers can pollute ports, waterways and oceans. In many instances vessels intentionally discharge illegal wastes despite foreign and domestic regulation prohibiting such actions. Ships create noise pollution that disturbs natural wildlife, and water from ballast tanks can spread harmful algae and other invasive species.

    Decision Making how will we manage the Essex coastline?

    4 star(s)

    Essex is made especially defenceless as it has also been hit had by isostasy. And this is why I eager you to make a decision upon who we will defend our Essex coastline. There are several areas in Essex becoming increasingly susceptible to flooding. In order to protect these areas action must be taken. This plan provides a long term strategic view on how the balance between losses and gains to Essex can be maintained in the light of rising sea levels, and the flood defence response to it. The plan concludes that Essex cannot be maintained in its present form.

    Development is hazardous to natural and build environments

    4 star(s)

    Economic growth can be helped by increasing the amount of contact within inland areas around Asia. "Rapid economic growth in recent years has put enormous pressure on Asia's transport, energy, and communications infrastructure. Unless these can be improved, they will continue to be a bottleneck to growth...Better connectivity with inland areas, for instance, would boost trade and economic growth in both coastal areas and inland...Following the 1997-1998 Asian financial crisis, countries with significant investments in infrastructure recovered faster than others...Consequently, regional infrastructure will need to be geared more towards supporting Asian production networks and regional supply chains to accelerate the return to the higher growth trajectory and further bolster the growth momentum."

    Why does Green Peace want Antarctica as a World Park?

    4 star(s)

    Ever since humankind began to explore the continent, from Amundsen and Scott's famous battle to the South Pole onwards, it had been noted that Antarctic ecosystems take years to recover from damage if they recover at all: a footprint in the moss can linger for decades before it disappears. This proposed World Park can also protect the delicate ecosystem like the Antarctic Treaty but even better let scientists make experiments while not harming the environment to see ways on how to deal with climate change.

    Earthquake in Kobe – A Natural Disaster Waiting to Happen

    4 star(s)

    The damage was recorded over a radius of 100 km from the epicentre. The earthquake also hit the cities of Osaka and Kyoto. The economic loss was worse than anything. It was the largest ever to be lost directly from a natural disaster. Directly from the shaking itself, around 13 trillion yen worth of damage was caused. This is around �100 billion and before, the loss of life, production, and business interruptions. The Destruction The amount of destruction left by the earthquake was enormous. Around one in every five building collapsed. A further eighty thousand were badly damaged.

    Describe and explain the economic and social costs and benefits of ageing and youthful populations

    4 star(s)

    The young and active population therefore has to work hard to support the dependant population so that they can obtain their pensions. However if there are too many elderly people then the country, for example the United Kingdom, which has an ageing population will become very strained. They are too many elderly dependant people to support, this occurs when the active population cannot equal by working the amount of money which the dependant population are taking from the government. Effectively the government is losing money all the time if this does happen.

    * Before 1914, the volcano had been dormant for over a century. * The eruption began on 11 January 1914. * Almost all residents had left the island in the previous days, in response to several large earthquakes which warned them that an eruption was imminent. * Initially, the eruption had been very explosive, generating eruption columns and pyroclastic flows, but after a very large earthquake on 13 January 1914 which killed 35 people, it became effusive, generating a large lava flow.

    Climate Change

    3 star(s)

    The average annual temperature of north-west Europe is about 9C above the average for our latitude. If greenhouse gas emissions continue to increase, the temperature and density of the sea water in the North Atlantic will change with dramatic consequences. The gulf stream may stop or be greatly reduced. This would mean that less heat is brought to north-west Europe - harsher winters and mild summers. Flooding The UK has experienced devastating floods throughout the last five years, which have affected thousands of people and caused millions of pounds worth of damage. Last Summer's floods shocked the country - Large town were cut off or under threat of flooding e.g.

    Letter about a volcanos DRAFT

    3 star(s)

    There are 16 major plates as you can see in the map. As the plates move about, they spread apart, collide, or slide past each other. Volcanoes occur when this movement occurs. As you can see the Caribbean is next to a plate boundary. This explains why eruptions happen in this area. There have been several eruptions in the Caribbean region such as Montserrat in 1995. St. Kitts has erupted 27 times and St. Eustatius last erupted 1,600 years before present. Future volcanic eruptions cannot be ignored. There are various dangers of volcanic eruption they are grouped under to headings: Environmental and Human.

    Volcanoes - Comparing Mount Fuji and Vesuvius

    3 star(s)

    The volcano is moderately young but has erupted several times and most of these eruptions have been somewhat large in size, but overall, Fuji has had 2 mainly damaging eruptions. Any volcanic eruption is normally caused by plate boundaries. Mount Fuji is an island-arc volcano which means that three plates are converging; the Philippine Sea plate, the Eurasian plate and the Okhotsk plate. The volcano's latest and most damaging eruption was in 1707 called The Hoei Eruption which started as an earth quake on the 11th of November.

    Outline the factors influencing a rivers flood hydrograph.

    3 star(s)

    One factor that impacts the graph is the type of bedrock. Bedrock can be permeable or impermeable. Impermeable bedrock, like shale, does not allow water to pass though it whilst permeable rocks such as chalk does. There are two types of permeable rock; porous, which contains pours that fill with and store water as well as pervious. Pervious bedrock is cracked and so allows water to run in its joints.

    Who has control of Antarctica? Well in the Antarctic treaty, In the first half of the 20th century, many countries claimed territory in Antarctica. In order to prevent future conflict, 12 countries signed the Antarctica treaty in 1959, which suspended all national clams to the as a continent for science, and stated that it should be used for peaceful purposes only. Today, 45 countries have signed the treaty, which is one of the most successful examples of international cooperation. Now how do we use Antarctica, Antarctica is used mainly for research, and could give answers relating to future climate change.

  23. 2011 Japanese Earthquake and Tsunami - causes and effects

    This causes a massive displacement of the water at the epicentre sending large amounts of water thrusted towards land. While the plates settled back down again, over 1,000 aftershocks were caused, some happening weeks after the initial shock. Effects Although the earthquake was very large, its positioning and Japan's high standard building prevented the earthquake from doing considerable damage. The majority of the damage was caused by the ensuing tsunami. The total death toll is believed to be around 15,800 with almost 6,000 injured and 3,800 missing.

  24. Earthquake

    Tectonic earthquakes Tectonic earthquakes are triggered when the crust becomes subjected to strain, and eventually moves. The theory of plate tectonics explains how the crust of the Earth is made of several plates, large areas of crust which float on the Mantle. Since these plates are free to slowly move, they can either drift towards each other, away from each other or slide past each other. Many of the earthquakes which we feel are located in the areas where plates collide or try to slide past each other. The process which explains these earthquakes, known as can be demonstrated with a green twig or branch.

Conclusion analysis

Good conclusions usually refer back to the question or title and address it directly - for example by using key words from the title.
How well do you think these conclusions address the title or question? Answering these questions should help you find out.

  1. Do they use key words from the title or question?
  2. Do they answer the question directly?
  3. Can you work out the question or title just by reading the conclusion?
  • Discuss what is global warming. And the effects that global warming gives and how to prevent it.

    "In conclusion, if there was no greenhouse effect then there would be no global warming. The greenhouse effect causes the global warming to increase as well as humans and other creatures influence. There are many ways to help prevent and protect both. If people try to help out, then it would be a longer process to keep the ozone layer healthy longer. But, nothing will be done until we as humans start helping out."

  • Discuss the causes of Global Warming

    "Therefore to conclude, although the 'natural greenhouse effect' does exist it is enhanced by the considerable role human activity has to play and although predictions have been made as to what the long term results will be, such as melting of polar ice caps which will cause coastal flooding and also a significant change in climate with more frequent tropical storms (UNFCCC), it can not be certain what positive feedbacks have already occurred."

  • It is no good trying to save the rainforest if it means putting thousands of people out of work. To what extent do you agree/disagree with this statement?

    "In conclusion, I think the Amazon rainforest should be saved as it is an important part of our lives and without it, we would be plunging into global warming into an even more alarming rate. The way to save the rainforest is to stop people wanting to destroy it and the way to do this is give people what they want from the forests without destroying them. With many people, this is money. Calling off the debt, in my opinion, is the best way to save the forests. Are we going to be remembered for saving humanity, or dooming it with cattle ranching, slash and ranch, illegal logging, deforestation and urbanization? We can still choose!"
