  1. The structure of the Earth and the impact of volcanic eruptions.

    Conservative plate margins: The plates are sliding past each other. They are moving in similar directions, but at slightly different angles and speeds. As one plate moves quicker than the other plate, they will get stuck and the build-up of pressure will cause them to release which will cause an earthquake. There was an earthquake on the San Andreas Fault in 1906 where the earthquake was 7.9 on the Richter scale and 3,000 people were killed and 225,000 people were homeless.

  2. The Savanna

    Climate Temperatures in the Savanna vary according to the season. The Savanna has two distinct seasons; the wet season and the dry season. The dry season is during the Winter. During the dry season most of the plants in the savanna shrivel up and die, some rivers and streams also dry up and most of the animals migrate to find food. There are cooler temperatures, clearer skies and lower humidity in the dry season than in the wet season. During the wet season all of the plants are lush and the rivers and streams flow freely.

  3. Causes of Global Climate Change

    There is also evidence to suggest that this was the reason for the little ice age. Another example of an external factor that affects global climate is orbital geometry. Variations in the Earth's orbit and tilt (called the Milankovitch variations) seem to have a link with climatic change. Colder, glacial periods have occurred when the Earth's orbit is circular and warmer periods when it is more elliptical. The tilt of the Earth's axis will also vary over time from 21.5� and 24.5�. The greater the angle of tilt, the hotter the summers are and colder winters are.

  4. Biomes of the world. Tundra, desert, grasslands and forest.

    * It supplies the bulk of the world's commercial softwood timber, which is used to make paper. Deciduous Forest * This biome is in the mild temperate zone of the Northern Hemisphere. Major regions are found in eastern North America, Europe, and eastern Asia. * Deciduous trees lose their leaves in fall. * The natural decaying of the fallen leaves enriches the soil and supports all kinds of plant and animal life.

  5. Essay on Melbourne's Water Supply

    Small amounts of chlorine are added to destroy any waterborne disease-causing microorganisms. The amount of chlorine added is equivalent to less than half a teacup in an average-size backyard swimming pool. Water in Melbourne is also fluoridated and lime is also added to raise the pH level of the water back to neutral, limiting the possibility of corrosion to household pipes and fittings. Although 80% of Melbourne's water is treated minimally 20% requires full treatment. Water from Sugarloaf Reservoir receives full treatment, as it is fed by water from the Yarra River, Maroondah Aqueduct, and the Sugarloaf Pipeline.

  6. Dominican Republic

    The Geographic features in Jakarta are very similar to the geographic features in the Dominican Republic. Like Jakarta it has soaring Mountain Ranges and in places vast green fertile land and beautiful beaches. This influences the tourism rate for both of these countries, which means the pollution rate in both countries is very high. Due to this, both these countries are considered third world countries. Both these countries are in the ring of fire, meaning there are lots of volcanic eruptions.

  7. For an example of a high income country that you have studied that has undergone employment structure change in recent decades: A. outline the changes and the reasons B. describe the effects in the broadest sense

    Also because the local economy is growing, there is more indirect employment. * The money that is being brought to the country creates a bigger trade balance; this is sometimes called the balance of payments. It is the difference of the value of the country's imports ad exports. * Brands like Nike subcontract local firms to hire the factory workers, this is a good thing because there is employment generated by the use of local factories, this is better than the construction of Nike's own factories making various local factories going out of business.

  8. Geography importance of the tropical rainforest

    This is because more than 25% of our modern medicines originate from tropical forest plants. Even so, we have only learned how to use 1% of these amazing plants, so imagine the possibilities if we could experiment with the other 99%! For example, quinine is a plant extract found in the Tropical rainforest. Native tribes paralyze animals with darts dipped in quinine. We call this natural store of medicines the gene pool. Genes are building blocks of life found in the cells of plants and animals.

  9. Canada's Fresh Water

    Canada's ocean coastline is the longest in the world and almost nine percent of its total landmass is covered by freshwater. Canada is near the top of water-rich nations, trailing only Brazil, Russia and China. Canada has about 20% of the world's freshwater but only seven percent of it is renewable. Almost 9%, or 891 163 square kilometres, of Canada's total area is covered by fresh water. With approximately 8% of its territory covered by lakes, Canada has more lake area than any other country in the world. Canada has 563 lakes having an area greater than 100 square kilometres.

  10. What Is a Glacier? Types Of Glaciers

    Gradually the grains grow larger and the air pockets between the grains get smaller, causing the snow to slowly compact and increase in density. After about two winters, the snow turns into ice. At this point, it is about half as dense as water. Over time, larger ice crystals become so compressed that any air pockets between them are very tiny. Types Of Glaciers Ice sheets- They are only found in Antarctica and Greenland, ice sheets are enormous masses of glacial ice and snow expanding over 50,000 square kilometres.

  11. Rainforest Diary

    It flows for more than 4,000 miles to discharge its waters in the Atlantic Ocean near Belem, Brazil. Along the way, about 1,100 tributaries latch on. One of the most seen birds was the Toucan. It was bigger then I thought it would be. Our guide told us that ten million species of plants, animals and insects live in the tropical forest. As it became dark, we stayed in the undergrowth of the forest where the tree could shade use from the hot sun we were expecting in the morning. The floor of the rain forest was sticky and wet from the rain that had fallen earlier this morning.

  12. New Orleans Geology

    The city was originally founded in 1817 by the French Mississippi Company. The leader of the expedition who is credited with the discovery was Jean-Baptiste Le Moyne de Bienville. It was built at this location to be used as a trade and shipping post because of its access to the Mississippi River which spans more than 2,300 miles north. The river was perfect for shipping because once the ships crossed the Atlantic Ocean, instead of having to travel west by land, they could just continue their sailing straight into the Gulf of Mexico, stop in New Orleans to resupply and continue up the river with no detour needed.

  13. Kobe and Haiti earthquake had many differences between the primary effects because in Haiti, 230,000 people died and in Kobe, only 6,434 people died, due to the face that Haiti is an LEDC

    The US Geological Survey estimates that 3.5 million people lived in the area where 'moderate to heavy' damage occurred. The Haitian government estimates that 230,000 people died, about 300,000 were injured and 1 million were made homeless out of a population of 10 million. Some 250,000 dwellings were destroyed or badly damaged. For any country, this would have been a major disaster. However, as a very poor nation, Haiti was particularly badly placed to cope with such an event. According to the World Bank (2008), Haiti's gross domestic product per person is only 660 US dollars. This makes Haiti the poorest country in the western hemisphere. It is ranked 149th out of 182 countries on the human development index.

  14. Tsunami newspaper

    It triggered tidal waves up to 30 feet high that swept into coastal villages and seaside resorts. The earthquake was felt as far away as Bangladesh, and the resulting tsunami was so powerful it has killed more than 225,000 people in eleven countries. A lucky survivor Chris Burke told us his tragic story. "The water pinned us between the railing and under a metal awning that had been covering the balcony.

  15. Walton on the naze field trip coursework

    On the northen side is the port of Harwich. There is a large breakwater here called land guard point. It traps beach material on the North side to prevent the deep water channel from becoming blocked. This allows ships to use the ports of Harwich and Felixstowe (known together as the Haven ports) at all states of the tide. The causes of erosion on the Walton coast is mainly down to Long shore drift and prevailing winds causing the waves to crash against the cliffs. We found this out by measuring the distance a Satsuma travelled along the sea in the space of 1 minute.

  16. Are the changes in Tsueng Kwan O and Hong Kong beneficial

    The overall development of the area to achieve such a goal has severely impacted our environment. In 1977, Tseung Kwan O had not yet been developed, and was comprised of beautiful mountains, beaches, and clear waters.2 It was not soon before these mountains were destroyed to create flat area for the apartment blocks and the bay was filled with reclaimed land so as to increase the possible living area.3 The total developmental area is about 1005 hectares (Hong Kong New Town Development).

  17. River Rother

    At mid point (Bodiam), we will use a tape measurer crossing via a bridge. At the lower course (Rye), we will either estimate or use a secondary source. The hypothesis we expect to be proven correct that the width does get bigger as you carry on down the rivers course. Depth At Battle and Sedlescombe we will measure the river's depth 5cm interval to find out the shape of the river channel. At Bodiam there is a bridge and at every meter we will measure the depth using a tape measure with a weight at the end to hold it down.

  18. La Mesa Watershed

    is 78-80 meters above sea level. The main river system in La Mesa is the Calumpit River. The land surrounding the reservoir is a plantation forest with over 12,000 species of plants. As a result it is not as dense in forest cover, and thus rain and sunlight get through more easily. The advantage of this is that there is more ground cover due to exposure to sunlight. Also in addition to La Mesa having lots of plant species, it can be said that it is a healthy environment because there is Lichen growing on the trees (Figure 1.1).

  19. Taal Volcano

    In the west, the oceanic part of the Eurasian plate (South China Sea basin) is being subducted under the 560-mile length of the Manila and Sulu trenches. This produces a scattered line of active volcanoes from Taal to Iraya in the small islands north of Luzon. However, between the two gigantic plates are 4 microplates being squeezed together, with Taal being on the smallest micro plate, it's western boundary being pushed by the Eurasian plat while it's southern boundary and eastern boundary are transform margins (Figure1.1). This means that Taal volcano lies on a conservative margin known as the Philippine Fault but there are two subduction zones and the fault connects the two subduction zones, which makes the plate margin destructive (Figure 2).

  20. Australia has had a considerable number of hazardous bushfires, the Ash Wednesday Bushfires of 1983 is one of Australias most devastating.

    Most of the Ash Wednesday fires were caused by an accidental ignition, for example in Cudgee, Mt Macedon, Monivale and Branxholme. The suspected cause for these fires was the clashing of electrical powerlines with tree branches. Bushfires can be influenced by several factors. It is primarily the weather conditions and geographical processes that dictate the behaviour and spread of a fire. Drought plays an essential part in the environment desiccating determining the spread of a bushfire. Due to lack of rainfall, vegetation such as dry grasses, parched native shrubs and other combustible materials build up and become fuel for the fire to burn.

  21. Vegetation Coursework

    The altitude of a place can affect the areas vegetation as the higher the altitude the more wind there is. Wind can cause soil erosion which means that the soils will not a have the nutrients to sustain a densely vegetated area. Availability of water body is a factor which determines the type of vegetation present in the area. Near rivers the vegetation is very dense as the soil has got a lot of nutrients; this is due to the pressure of the silt.

  22. Vistors centre assessment

    The Pub Landlord and the National Park Ranger both agree for this plan to happen because it will get more money to the village, to teach tourists about this amazing area with natural and traditional features, and offer more jobs for young folks including to attract more tourists and offer opportunities for this national park to be the biggest tourist attraction including to be already the top 12 national parks in Britain. In addition the Peak District is quiet and calm so it is sparsely populated where only elderly residents, farmers and some people are only there.

  23. Free essay

    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?

    Some people Log to get wood so that they can make lots of money. Some people mine to get essential materials for today's advancing technology. But is it essential to destroy forests just to mine? After they have finished wrecking the perfectly beautiful, natural wonder, it will never be the same. With no tree's to protect it, the ground dries up and the forest turns into a desert. Nothing will ever grow there again. Three acres of rainforest are lost every two seconds. That's 90 acres a minute, 5400 acres an hour and 129600 acres a day!
