Because they reflect solar energy back into space they have a cooling effect on the world. The greenhouse gas, carbon dioxide is also produced however the CO2 produced is insignificant when compared to emissions created by humans. (see also featured article - Do Volcanoes cause climate change) Ocean current - The oceans are a major component of the climate system. Ocean currents move vast amounts of heat across the planet. Winds push horizontally against the sea surface and drive ocean current patterns.
Hurricanes and their impact on the environment The effect of hurricanes on the environment is catastrophic. The loss of life and damage to property and the environment has far reaching implications, for persons that survive these disasters. According to Remote Sensing Using Satellites,(n.d.)”A hurricane is an intense, rotating oceanic weather system that possesses maximum sustained winds exceeding 119km/hr (74 mph). It forms and intensifies over tropical oceanic regions”. Hurricanes normally develop in the Atlantic Ocean, Caribbean Sea, Gulf of Mexico and the North Pacific Ocean.
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.
They strengthen when water evaporated from the ocean is released as the saturated air rises, resulting in condensation of water vapor contained in the moist air. There are several similarities between hurricanes and tornadoes. First of all, both are unpredictable, incredibly devastating and can easily kill. Other than that, both are made up of very strong and fast wind which is more than 100 mph. Furthermore, both of them rotate all around.
Then the low-pressure system matures along the west-to-east atmospheric highway also known as jet stream; then a storm will move slowly along the jet stream that would produce the large waves (Warshaw 2000). When the waves are created we have to take into consideration that the bottom of the wave since it is a great factor in why the
First, the melting of ice caps and glaciers is releasing water into the oceans. Second, human activities, such as the burning of fossil fuels, combined with natural activities, it causes the rise of the earth's surface temperature.3 Second, climate change is already having a serious effect on every continent and throughout the world’s ocean. The consequences of sea level rise mainly reflected in three aspects: cultural heritages, indigenous communities and coastal lands. 4 First, sea level rise threats cultural world heritage. Data shows that 136 out of 700 listed cultural heritages throughout the world will be affected in the long term.
The heavy rainfall started falling at midday on the 16th August, and it was recorded that 5 inches fell in 8 hours. The storm was a remnant of the Hurricane Alex, which had carried over the Atlantic. The rain was cause due to warm air picking up moisture - due to residual heat from the Atlantic sea - travelled towards the South West Cornish coast as prevailing winds. Upon contact with the topographically vertical coast, these winds experienced a strong up-drafting force thus causing internal moisture to reach the atmosphere, and consequently cool as a string of storm clouds. With convergence and coalescence, enhanced moisture levels resulted in heavy rainfall on the afternoon of 16 August 2004.
Scientists studying the polar ice caps have observed consistent annual increases in the rates at which they are melting; this indicate, that the temperature of Earth’s water is increasing and sea levels are rising. In July of 2013, the temperatures at the North Pole where up to five degrees above average, in fact it was so hot that the melting ice caps formed a lake on top of the world (Breslin). Increasing water temperatures could cause hurricanes to be stronger in force and frequency; image Hurricane Sandy but stronger and on a consistent basis. Along with rising temperatures comes rising sea levels which means that all land with altitudes below sea level are at risk of becoming submerged. The U.S. eastern seaboard is particularly vulnerable, including the entire state of Florida and cities such as New York City, Washington D.C.,
When the sun and moon are at a right angle, the pulls fight each other and cause a smaller difference between high and low tides called neap tides. Another type of motion is waves. Everything in the water causes waves, but the most common thing is wind. When wind passes over the surface of the water, friction causes it to ripple. The strength, distance, and length of the wind gusts determine how big the ripples become.
The Effects of Hurricanes Hurricanes also known as Cyclones are amongst the strongest storms on earth, which have plagued man for centuries. Jay Barnes confirms this timeline, with this passage “They are called hurricanes in the Western Hemisphere, a term probably derived from ‘Hurukan,’ the name of the Mayan storm god, and other similar native Caribbean words translated as ‘evil spirit’ or ‘big wind’.” ( 6). Every year, in the summer season, these forces of nature begin to form themselves sometimes less numerous then the year before and sometimes in greater numbers witnessed in a decade. For future reference hurricanes are often named, not only to keep track of them but also people that have experienced them, tend to remember these storms by their name. They are born from tropic waters that affect quite a few across the world but in the Gulf of Mexico they tend to wreak particular havoc.
