passage carefully and answer the questions that follow. Glaciers Besides the earth’s oceans‚ glacier ice is the largest source of water on earth. A glacier is a massive stream or sheet of ice that moves underneath itself under the influence of gravity. Some glaciers travel down mountains or valleys‚ while others spread across a large expanse of land. Heavily glaciated regions such as Greenland and Antarctica are called continental glaciers. These two ice sheets encompass more than 95 percent of

Water changing the face of the Earth Many things change the surface of the earth‚ and one of those things is water. The course of rivers and creation of lakes can be attributed to receding glaciers‚ and rivers have made changes to landscapes from steep mountains to flat floodplains. As well as humans creating many changes in the flow and direction of rivers and creation and draining of lakes. Some changes happen very rapidly‚ such as building a dam and creating a lake within a short period of time

The melting of the Arctic and Antarctic ice is a result of climate change. This climate change includes the decline of sea ice‚ rising temperatures and the melting of the Greenland ice sheet and the Antarctic ice sheet. The Antarctic Ice Sheet covers around ninety-eight percent of the Antarctic continent and is the largest body of ice on earth. The Greenland Ice Sheet is the second largest body of ice; it covers more than eighty percent of Greenland. The Ward-Hunt Ice Shelf is the largest single

“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 revolution and fossil fuels output green house

The concepts of how these environmental changes effect the human ability to enhance ecosystem services will be explored. The normal increase in temperature is only one degree throughout the world within the past 30 years‚ but is sufficient to start the melting of polar caps in the Arctic and raise the sea level. The melted white ice tends to reflect

Minnesota A glacier is a large piece of ice on land‚ normally formed over time. A glacier forms when snow falls and compresses together to form the large mass of ice over time. The glaciers can move because of gravity‚ and the smoothness of the glacier. Glaciers were present in Minnesota thousands of years ago‚ and as they retreated they left behind large amounts of glacier meltwater and various landforms still present today.Glaciers are both constructive and destructive. The glaciers are constructive

global warming is one that is caused by us humans. They have many facts data to back this up. Some examples of these facts and data are the change in CO2 levels in the atmosphere‚ the rapid increase in temperature‚ stronger storms such as hurricanes‚ melting ice caps‚ decrease in permafrost‚ and the Larsen A & B ice shelves. These are some of the biggest points that help scientists show the damaging effects that Global Warming has on our climate. Between the years 1973 and 1999 the amount of CO2 has steadily
