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.
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...
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. Thirdly; small, almost enclosed seas, like the Mediterranean or North Sea, often generate huge waves during storms. Waves move within the sea but cannot disperse their energy – rather like water slopping up against the side of a washbasin. Lastly the sea floor is deep along the coast. Therefore, the waves reach the cliffs without
The associated air masses of storms within the British Isles are Polar maritime and Tropical maritime. As these two bodies of air move towards each other the warmer, less dense air from the south rises above the colder, dense air from the north. Circulations of low pressure then develop at points where the air is rising vigorously, this then coincides with waves in the polar front and jet stream. As a consequence there is much unsettled weather including heavy rain, strong winds and a variety of stormy cumulus clouds form; all of which can have devastating impacts socio-economically for an area as well as on the environment. The storm of 1987 occurred on the 15th and 16th of October due to a depression forming within the Bay of Biscay and had disastrous effects on the south and south-east of the UK.

When water freezes, latent heat is also released, warming the air in contact with the forming ice. Latent heat plays an important role in the redistribution of heat on the surface of Earth, especially through evaporation in the tropics and subtropics and the subsequent precipitation in higher latitudes. Secondly the warm waters sets up a low-pressure region around Iceland, reaching over the Norwegian Sea. The Icelandic Low acts as an enormous whirlpool sucking in warm air from the subtropical regions on top of the Gulf Stream and sending much of the heat to Norwegian shores. The transport of heat by the warm ocean
The surface of Mercury and the moon share similar physical characteristics but also differ in certain aspects as well, outlining variations in their respective geological histories. In general, both the moon and Mercury show great similarity in size and from their substantial amount of craters which can be attributed to their lack of a prominent atmosphere that would burn up any primordial impacts. However, a closer look shows many differences. For example, the moon has 14 maria (lava flow regions), a relatively large number when compared with Mercury as it has few maria. This gives us a hint as to how fast Mercury and the moon cooled in relation to each other, as the cooler planet would
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 factor was ultimately the one which caused all the damage and devastation for the habitants of N.Y if it wasn’t for the high pressure, the hurricane would have carried North rather than the quick turn forcing Sandy onto landfall. The geography of N.Y also made it more susceptible to storm surges. The long and narrow shape of the Long Island Sound helped to channel the waves in the 12 foot storm surge, making it even bigger. Additionally, areas such as Battery Park were built from landfill and therefore are low-lying areas and also flat.
