describe the sketches the various types of moraine developed by depositional work of glacier.
Answers
Answer:
Glaciers cover about 10% of the land surface near Earth’s poles and they are also found in high mountains. During the Ice Ages, glaciers covered as much as 30% of Earth. Around 600 to 800 million years ago, geologists think that almost all of the Earth was covered in snow and ice. Scientists use the evidence of erosion and deposition left by glaciers to do a kind of detective work to figure out where the ice once was.
Formation and Movement of Glaciers
Glaciers are solid ice that move extremely slowly along the land surface (Figure below). Glacial ice erodes and shapes the underlying rocks. Glaciers also deposit sediments in characteristic landforms. The two types of glaciers are:
Continental glaciers are large ice sheets that cover relatively flat ground. These glaciers flow outward from where the greatest amount of snow and ice accumulate.
Alpine or valley glaciers flow downhill through mountains along existing valleys.
