This essay will firstly discuss the extent to which the impacts of storms in the UK, such as ‘The Great Storm’ of October 1987 in Southern England and the recent St Jude’s storm in October 2013, are the result of physical and human influences, and then evaluate the effectiveness the responses to these storms. On one hand, it must be argued that physical factors are key in determining the magnitude of impacts from UK storm events. Factors such as the depth of a depression, the intensity of the pressure gradient and the resulting strength of winds as well as a storm’s path are key in determining the magnitude and nature of the effects of storms, particularly the economic impacts. The Great Storm in 1987, for example, which developed as a severe depression in the Bay of Biscay (964 millibars) and moved northeast, was the worst recorded climatic event in the UK. The hurricane strength winds which gusted up to speeds of 10 knots in the south-east England caused more than 15 million tress to fall down, blocking roads and railways and leaving widespread structural damage to more than 15 million buildings.
Discuss the impacts of storm events in the British Isles and evaluate responses the responses to them. (40 Marks) Storm events in the British Isles are caused by depressions which form out in the Atlantic Ocean and are brought to us mainly by the tropical maritime air mass moving north-east over the British Isles. A depression is a low pressure weather system formed where two different air masses meet along the polar front, this occurs rapidly as they are driven by prevailing westerly wind. They appear as masses of swirling clouds when viewed on satellite images, subsequently due to Coriolis effect resulting in an anticlockwise rotation in the northern hemisphere. The associated air masses of storms within the British Isles are Polar maritime and Tropical maritime.
Oklahoma, Kansas, the Northern Texas, and the New Mexico) which experienced severe soil erosion caused by the effect of windstorms in the 1930s. Lassieur (2009) noted that the term has its origin from WW I, during which the initially known grasslands of the area were converted into agricultural fields. The area had experience dry climates leading to severe drought. Together with the effect of over-cultivation, which occurred in the early parts of 1930’s, the land in the Great Plains ware left bare? This condition made the soil to be more prone to the heavy winds, which blew the loose topsoil in what was described as the black blizzards.
This knowledge of plate margins and their movement against one another can help us to understand the distribution of seismic and volcanic events and this is because the majority of events are associated at these plate margins. Wegener’s theory of plate tectonics suggests that all the continents were once joined together in a super continent called Pangea and have since drifted apart due to plate tectonics. To add to this, Sea floor spreading was discovered showing that rock is being created and destroyed, leading us to believe in the existence of plates and plate boundaries. Wegener gained evidence from paleo magnetism and suggested that there were numerous reasons and pieces of evidence for the continents drifting apart. Biologically, there was evidence that proved his theory for example, the Mesosaurus reptile fossils were only found in Africa and South America, proving his ‘jig-saw’ fit idea.
Tornadoes are responsible for more than $1 billion annually (adjusted to 2007 U.S. dollars) in property damage and for disrupting thousands of lives and businesses. On the local level, the impact of a tornado can be devastating within the area that it destroys . When a tornado hits a human environment, however, more extensive damage can happen. The impact of the tornado can include releasing chemicals, oil, and other toxins, into the environment, doing more extensive damage over a broader area. While this is not a major concern, especially compared to other potential causes of damage, it is a reason to make certain potentially hazardous materials are secure.
The evidence of sea floor spreading was further supported by Vine and Drummond, who studied the magnetic pattern of the sea floor. They found that the Earth’s magnetic field changes over time, because as magma from the mantle rises to the crust it cools but the basalt will align to the field it cools to. It is also found that on either side of mid oceanic ridges there were symmetrical magnetic patterns, so suggesting that the ocean was created at the mid oceanic ridges and as new ocean floor cooled, it pushed the crust away. Both Hess and Vine and Drummond found evidence that is crucial to the explanation of how continental drift happened, and it is very important in the development of geologists understanding, however other people found evidence to support continental drift also. Dan McKenzie went on to further explain sea floor spreading, being able to explain why new crust was made at mid oceanic ridges.
June Avant English 101 November 22, 2010 Global Warming Controversy Global warming is an increase in the average temperature of the earth’s atmosphere which causes climatic changes. Global warming leads to changes in rainfall patterns, sea level, negative impacts on plants, wildlife, and humans. Al Gore and Daniel Botkin both have great points about global warming. Botkin has a scientific perspective about global warming; however, Gore’s position is better. Al Gore uses facts and evidence to support his views about global warming.
At last for conservations margins, the tension build up when plate are grinding past each other get stuck. Afterwards the plate will finally jerk past each other and sending out shock waves which is vibrations which is earthquakes. They both create lots of impact. For examples for the volcano eruption in Montserrat which is a LEDC, it cause 19
There were also the same fossilised pollen species and rock sediments on these coastlines. Wegener’s ideas were further proved and built upon by other ‘geographers’ which has increased our understanding of tectonics events today. Sea floor spreading was discovered which showed that rock is always being created and destroyed; this lead us to believe in the existence of plates and plate boundaries across the lithosphere. Sea floor spreading has been shown to exist in the Atlantic Ocean where the theory is that the Eurasian and North American plates are moving apart, at what is called a constructive plate boundary. This is where magma rises through a rift and cools
Their discovery prompted astronomers around the world to look in places where planets were not found to exist and allowed us to further examine how a planet can exist at such extreme temperatures. The methods and thought processes by Mayor and Queloz are essential in
