Question

what are glaciers? described the erosional and depositional features caused by glaciers:-

please answer in detail
it's a 7 th class question of geography​

Answer 1

Glaciers are made up of fallen snow that, over many years, compresses into large, thickened ice masses.

As the glaciers expand, due to their accumulating weight of snow and ice they crush and abrade scour surfaces rocks and bedrock. The resulting erosional landforms include striations, cirques, glacial horns, arêtes, trim lines, U-shaped valleys, roches moutonnées, overdeepenings and hanging valleys.

Answer 2

Answer:

Glaciers are made up of fallen snow that, over many years, compresses into large, thickened ice masses. Glaciersform when snow remains in one location long enough to transform into ice. What makes glaciers unique is their ability to move. Due to sheer mass, glaciers flow like very slow rivers.

Explanation:

U-shaped valleys, hanging valleys, cirques, horns, and aretes are features sculpted by ice. The eroded material is later deposited as large glacial erratics, in moraines, stratified drift, outwash plains, and drumlins. Varves are a very useful yearly deposit that forms inglacial lakes.
