Section A - Restless Earth The earth’s structure At the centre of the earth is the core. Surrounding that is a mass of molten rock called the mantle. The thin layer on the outside is called the crust. There are two types of crust‚ continental and oceanic. The crust is made up of seven major plates and many smaller ones. The plates move due to convection currents rising in the mantle. Distribution of earthquakes and volcanoes Mainly found along plate boundaries. In

Reading Assignment: Chronicles of Ice Summary: In Chronicles of Ice‚ Gretel Ehrlich sets out to “learn whatever lessons a glacier has to teach”‚ and to share what she has learned with us‚ as readers. The lesson the author relays to us is that the fate of the glacier is inextricably linked to that of the biological health of the Earth itself. Ehrlich uses the glacier as a device to show both cause and effect of the declining health of the Earth’s climate. The gases and particulate trapped in the ice

Rocks within the Wildcat creek were eroded before glaciers passed through the area. When glaciers did pass through‚ they left behind glacial drift which resulted in the valley. With this‚ there

Ehrlich and Saukko are both worried about the effects of human activities on the environmental and what we can do to stop poisoning the Earth and save the glaciers. Both realize the human action on the environment and the effects they do have on Earth. Saukko idea is completely theoretical‚ highly illegal‚ and almost impossible to happen. Poisoning the earth can be difficult

Ice is also what forms glaciers‚ and this features prominently in another one of Eliasson’s works The Glacier Series. These massive formations not only form slowly but also move slowly‚ much slower than the human eye can perceive‚ much less the attention span wishes to

form of glaciers. Mono Lake was also a part of the agenda on the immersion experience. At the lake‚ we learned that its salinity is caused by the lack of an outflow for the lake and we discovered the volcanic history of the Mono basin. During the same summer I was gawking at Mono Lake‚ I also road tripped to Glacier and Banff National Parks with a few friends. We not only had the opportunity to see some of the most magnificent mountain ranges‚ we were also able to see the receding glaciers that formed

that we have plenty of water for our needs. But really‚ about 97% of that water is made up of ocean. We cannot use this water because it is too saline for our needs. Only 3% of Earth’s water is fresh‚ and 2% of that supply is frozen in ice caps and glaciers. That leaves us with only 1%. Demand for water increases every year. The tricky thing now‚ is to figure out how to use our water wisely. The United States have been lucky to have plentiful water supply. Water has been cheap and people have
