Pre A level task Geography Erosional landforms: Corrie = Corries‚ also known as cirques‚ are often the starting point of a glacier. Snowflakes collect in a hollow. As more snow falls‚ the snow is compressed and the air is squeezed out to become firm. With the pressure of more layers of snow‚ the firm will‚ over thousands of years‚ become glacier ice. Erosion and weathering by abrasion‚ plucking and freeze-thaw action will gradually make the hollow bigger. Corries will decrease because of

Wisconsin Glaciation of Minnesota Glaciers are massive chunks of ice that float in the sea or on land that move incredibly slowly. These ice globs are so large that they have the power to shape and carve land over long periods of time‚ a process called abrasion‚ and often taking hundreds to thousands of years. Currently‚ most glaciers are found in Antarctica and Greenland. This paper will explore a specific glaciation period called the Wisconsin Glaciation and the effects it had on Minnesota.

"Extreme Ice" In this documentary film‚ “Extreme Ice‚” produced by PBS TV‚ 2009‚ James and scientists shows how glacier ice is melting. James Balog‚ a photographer‚ wanted to document and help scientists to understand mountain monumental changes. So he surveyed the ice and went to the places such as Alaska‚ Green land‚ etc. The project team which called “Extreme ice” discovered that there were very serious problems. The sun was the most reason of ice melting. But now‚ such as Industrial

well. Some trees may grow back if they are starting to wither away but they will also have to manage to live with the other imported trees from all over the world. In the book‚ Weisman stated alarming fact that a glacier is due to flatten Manhattan any day now since the last glacier left eleven thousand years ago. Weisman brings up a good point stating “if we continue to increase our carbon emissions‚

Shrinking Glaciers 4/10/12 As a direct result of anthropogenic induced climate change there have been a number of observed changes to our environment and potential hazards created that threaten our planet. Along with increased storm frequency‚ abnormal precipitation patterns‚ and increasing sea levels that grab the headlines in the news‚ a very critical issue is threatening mountain communities across the globe. With each subsequent year global mean temperatures rise‚ mountain glaciers are shrinking2

In the controversy over whether Global Warming there is two sides in which people can choose either human caused or just Mother Nature doing her thing. Most scientists will tell you that Global Warming is mostly the cause of humans. While there are some who will disagree and say that it is just nature doing what it has done for thousands of years. For most scientists the topic of global warming is one that is caused by us humans. They have many facts data to back this up. Some examples of these

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

all of North America in over 6‚000 feet of snow and ice. During this time‚ the temperatures went up and down causing the glaciers to melt or to expand‚ often times causing them to move. This carved the landscape of Michigan (Why). Glacial erosion can happen in two primary ways‚ the first is called plucking‚ and this happens when rocks and debris stick to the underside of a glacier and then are carried off with it. The second is called abrasion‚ this is more of what we might think on when we think of
