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.
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
Due to this convergence (where winds move to a center point), air is forced to rise over that area. If enough moisture is available, the rising air cools and condenses (as cold air cannot hold water vapor below a certain temperature) into tiny water droplets which constitute the cloud. So, low pressure areas are usually the birth-place of clouds. Sometimes, particularly in the winter, fog forms over a high pressure area due to radiation cooling(due to clear sky conditions over a high pressure area).This fog sometimes lift and forms thick low cloud called "anticyclone gloom".

El Nino – The phenomenon and its effect and its effects on southern Australia El Nino is a strange weather phenomenon that that is caused by the warming of the Pacific Ocean near the equator, off the coast of South America. This happens when the normal winds weaken which allows the warm water that is usually found in the western Pacific change
-”Wegner used the shapes of matching shorelines on different continents as a supporting piece of evidence for continental drift. 3. Describe Earth's magnetic field, including how it has changed through time. -Similar to a simple bar magnet, ends have opposite polarities that cause magnetic objects to align parallel to it’s magnetic field. Poles have wandered from geographical position over the years.
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.
The marine biome is located by the ocean or sea in lots of places. It might as well be surrounded by water even though it doesn’t have to be. For example, Haeundae is a marine biome because the sea meets the shore down by the Haeundae Beach. Abiotic factors Temperature affects the density of substances, and changes in the density of water means more or less resistance for animals who are travelling in the freshwater environment. Tide is the alternate rising and falling of the sea, usually twice in each lunar day at a particular place, due to the attraction of the moon...
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.
This precious necessity distributes from the ocean into the earth’s atmosphere. With the earth covered by 70% water one could conclude with each breath taken the health of a living system is, depending on the health of the ocean. The National Oceanic and Atmospheric Administration (NOAA) are examining the effect on the health of living systems and how a direct contrast to the oceans health may render solutions or expose risks. Solutions such as medicines extracted from the ocean formulated to help save lives. Exposing health risks associated to contaminated seafood, drinking water harmful to human consumption and polluted beaches.
