Hurricanes occur in MEDC's (More Economically Developed Countries) and in LEDC's (Less Economically Developed Countries). They affect both areas however; both areas react and respond to them in different ways using different resources and aid sources
Natural Hazards
1, a) Outline the causes of any 2 different types of hazards
Hazards are possible sources of danger. Types of hazards are those such as hurricanes, earthquakes and volcanic eruptions. A cause is what makes something happen and is a reason for it happening. The two types of hazards I will be outlining the causes for are hurricanes and earthquakes.
A hurricane and tropical storms are cyclones. When the winds reach a constant speed of 74 miles per hour or more, it is called a hurricane. A hurricane is caused when a large mass of air is warmed up and the warm humid air begins to rise. As the air rises, it cools and condenses to cloud and rain. They are tropical storms. The hurricanes winds blow in a large spiral around a calm centre called the ‘eye’. The eye is usually 20-30 miles wide and the storm itself may have a diameter of 400 miles. As a hurricane approaches, the skies begin to darken and the winds grow stronger. The hurricane can bring torrential rains, high winds, and storm surge as it comes close to land. A single hurricane can last more than two weeks.
An earthquake is a shaking movement of the earth’s surface. It results from faults. The earth’s surface is in continuous slow motion. This is plate tectonics – the movement of rigid plates at the surface of the earth in response to flow of rock within the earth. These plates cover the whole surface of the earth. Since they are all constantly moving, they rub against each other at the boundaries (for example, the San Andreas Fault in California). They sink beneath each other, or spread apart from each other (like the Mid-Atlantic Ridge). At such places the motion becomes less smooth - the plates are stuck together at the edges but the rest of each plate is continuing to move, so the rocks along the edges are distorted. As the motion continues, the strain builds up to the point where the rock can not stand any more bending. With a lurch, the rock breaks and the two sides move. An earthquake is the shaking that radiates out from the breaking rock.
