Sea floor spreading forms the best evidence for continental drift. Critically discuss this statement. There is lots of evidence to support the theory of continental drift, including Harry Hess’s discovery of sea floor spreading theory. By using sonar, Hess found that oceans were shallower in the middle, allowing him to identify Mid Ocean Ridges. He suggested that at the centre of oceans, molten material would rise from the Earth’s mantle, causing new sea floor to be created, pushing the ocean floor.
Personally, I believe that these 2 factors were very important as much of the damage was due to water rather than the 80 mph winds Sandy brought. At the time of Sandy moving North up the East coast. There was a very high-pressure system in the middle of the Atlantic, jet-streams push the hurricane towards the East Coast, hitting New York. People were not expecting this dramatic 90 degree turn; this increased the damage made due to the lack of planning. This was the most shocking fact that Sandy produced, usually when a storm makes it up to the Northern mid-Atlantic latitude, it is always way out to sea, but Sandy did otherwise.
This is not far, compared to some of the world’s large oceans, but the size of the waves attacking the coast is increased by four other factors. One is the currents or swell, which circulate around the UK from the Atlantic and into the North Sea. The Atlantic fetch is 5000 km or more, and its currents add energy to waves in the North Sea. Therefore, there are often powerful destructive waves along the coastline, eroding the cliffs. The second point is the low pressure weather systems passing over the North Sea are often intense, and locally produce very strong winds and waves.
Hurricanes Hurricanes, also known as tropical cyclones, are low pressure storm systems that form on open water and feed on heat released when moist air rises. Hurricanes are recognized on radar by their distinct pin wheel shape. When hurricanes begin to take shape they are called a tropical storm. The word “tropical” is used because most of these storms are formed by the very warm water of the tropics. Hurricanes need the ocean’s water temperature to be about 80 degrees to a depth of about 150 feet.
One more similarity is the equipment they used to get the results for example they both used temperatureDetermining global warming effects on weather can be done in many different in these two articles I found that you can use ice or water. In the rising of the seas they explain how the melting of the ice caps raise the sea level but in the greenhouse. It breaks down how they can use ice to determine the future weather. Global warming is something more people need to be aware of and get more knowledge on, because after reading these two articles I found out what our world might become just by looking into the past. These two article had there similarities and differences in how they go about finding out about the past but yet both are very
(live science.com) One of the most memorable rogue wave occurrences was on October 30, 1991. It was called the perfect storm. According to CNN.com, an enormous extra tropical low is creating havoc along the entire Eastern Atlantic Seaboard in this infrared image at 1200 UTC (0700 EST) on October 30, 1991. Labeled the "perfect storm" by the National Weather Service, the storm sank the sword fishing boat Andrea Gail, whose story became the basis for the currently best-selling novel "The Perfect Storm" by Sebastian Junger. Ocean waves peaked at 100 feet, the height of 10-story 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.
Describe sea floor spreading and explain why it is an important piece of evidence for advancing plate tectonics. -It is a theory where land is created at the ridges and is then split apart. 7. Describe the general relationships that exist among the following: distance from spreading centers, heat flow, age of ocean crustal rock, and ocean depth. The farther away the older, the closer to the spreading center the warmer and more active.
The Garbage Patch was formed by a bunch of reasons as though you suppose. It is said that it was a result of marine pollution gathered by ocean currents in the Pacific. The Garbage Patch occupies the North Pacific Ocean and the North Pacific Gyre. Because of the gyre’s direction that it moves in the waste gets drawn into and the garbage cant get out of the current. As the garbage is caught in the currents wind currents move the floating debris to the center making the garbage unable to get out of the center.
What is the fault Its notoriety comes partly from the disastrous 1906 San Francisco earthquake, but rather more importantly because it passes through California, a highly-populated state that is frequently in the news. And with many research institutions dedicated to studying such an accessible fault, the SAF has become a household name. But what is a fault? And what is the SAF? A fault is a planar crack in a rock along which slippage has taken place.
