Dạng bài Đọc hiểu lớp 12
Read the following passage and mark the letter A, B, C, or D to indicate the correct answer to each of the questions from 46 to 55.
There are two basic types of glaciers. those that flow outvvard in all directions with little regard for any underlying terrain and those that are confirmed by terrain to a particular path.
The first category of glaciers includes those massive blankets that cover whole continents, approximately called ice sheets. There must be over 50,000 square kilometers of land covered with ice for the glacier to qualify as an ice sheet. When portions of an ice sheet spread out over the ocean, they form ice shelves.
About 20,000 years ago the Cordilleran Ice Sheet covered nearly all the mountains in Southern Alaska, western Canada, and the western United States, It was about 3 kilometers deep in its thickest point in northern Alberta. Now there are only two sheets left on Earth, those covering Greenland and Antarctica.
Any domelike body of ice that also flows out in all directions but covers less than 50,000 square kilometers is called an ice cap. Although ice caps are rare nowadays, there are a number in northeastern Canada, on Baffin Island, and on the Queen Elizabeth Islands.
The second category of glaciers includes those of a variety of sliapes and sizes generally called mountain or alpine glaciers. Mountain glaciers are typically identified by the landfrom that controls their flow. One form of mountain glacier that resembles an ice cap in that it flows outward in several directions is called an ice field. The difference between an ice field and an ice cap is subtle. Essentially, the flow of an ice field is somevvhat controlled by surrounding terrain and thus does not have the domelike shape of a cap. There are several ice fields in the Wrangell, St. Elias, and Chugach mountains of Alaska and northern British Columbia.
Less spectacular than large ice fields are the most common types of mountain glaciers: the cirque and valley glaciers. Cirque glaciers are found in depressions in the surface of the land and have a characteristie circular shape. The ice of vallcy glaciers. bound by terrain. flows down valleys. curves around their corners. and falls over cliffs.
