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.
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
Where is all this melting ice going? “Sea level rise is caused by two factors related to global warming: the added water coming from the melting of land ice and the expansion of sea water as it warms up” (Global Climate Change: Key Indicators, 2014). All these indicators data need to be studied as
Hurricanes need the ocean’s water temperature to be about 80 degrees to a depth of about 150 feet. Another factor of the forming of hurricanes is the rapid cooling of the warm water vapors that were evaporated, which causes condensation (the second step of the water cycle). The third step of the water cycle is precipitation and that happens when too many water vapors are condensed and rain starts to fall. Humidity is also needed in the
Throughout and after an ice age, eustatic change takes place. At the start of an ice age, the temperature falls and water is frozen and stored in glaciers inland, suspending the hydrological cycle. This results in water being taken out of the sea but not being put back in leading to an overall fall in sea level. Conversely, as an ice age ends, the temperature begins to rise and so the water stored in the glaciers will renter the hydrological cycle and the sea will be replenished, increasing the sea levels. Increases in temperature outside of an ice age will also affect the sea level
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.
Over the years we have seen the change grow rapidly. Firstly the greenhouse gas emissions are the main cause of climate change. The five following gasses contribute to the greenhouse gas effect: Water Vapor, Carbon Dioxide (CO2), Methane, Nitrous Oxide, and Chlorofluorocarbons (CFCs). Water Vapor is the most rich greenhouse gas. It increases as the Earth’s atmosphere warms which makes it the most feedback mechanisms to the green house effect.
This happens when the normal winds weaken which allows the warm water that is usually found in the western Pacific change direction and instead move towards the east. This warm water replaces the cold water which is normally found near the surface of the eastern Pacific. All these occurrences are what affects a lot of weather patterns in many parts of the
Gore also asserts that global warming is caused by over population. Toxins and chemicals in the atmosphere impact each individual in the world. Because of the effects of global warming, the strength of hurricanes can change easily and cause an enormous amount of
Tule fog is a very thick fog that collects in parts of California during the rainy season of the late fall and winter. It has also been known to gather from Bakersfield to chico and occasionally in San Francisco. Tule fog is a type of radiation fog that is created due to the rising of warm air. http://www.wisegeek.com/what-is-tule-fog.htm The cold mountain air descends into the San Joaquin Valley and usually forms Tule fog on the first or second clear night after it has rained, skies are cleared and winds are light. This happens when high-pressure returns, creating an inversion with colder air near the earth's surface than aloft.
