Question

explain how different types of landforms are formed by glaciers

Answer 1

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

$\huge{HEY!!}$ ___________________________________

⚫Mountain glaciers carry debris of rocks in the lower parts, and the accumulation of such debris is called moraine.

⚫The glaciers form step - sided wide valleys which seem to be U - shaped. these valleys are called Glacier troughs.

⚫There are many smaller troughs too, with steep walls called cirques, some of which contain lakes and Tarns.

⚫Glaciers also form narrow deep valley with steep sided called fjords.

⚫The glaciers of polar region are ice sheets which are thousands of metres thick. Often, huge blocks of ice break off and drift into the open sea and icebergs.
