Question

Explain What is Cirque and Horn

Answer 1

Hello friend

___________________________

Here is your answer!!!

Landforms produced due to erosional work of the glaciers.Both the landforms are produced in the areas where the glaciers originate.After snowfall,the snow doesn't start flowing immediately like water,it gets deposited.It deposits more at the base than the slopes.

When many layers of snow get deposited, the lower layers face pressure from above and turn into ice.While turning into ice and because of pressure,some ice at the bottom turns into water due to friction.This water starts flowing along the slopes.This flow is the starting point of glacier.


Ice on the slope also Starts moving downwards.Friction causes the slopes for the mountains to become Steep.Moving ice gets deposited at the foothills.Weathering by melted water leads to deepening basal portion.Such deepened portions at the base of slopes are called cirques.

The cirque and the mountains behind it with steep slope together look like a big armchair and therefore,cirque are often called gigantic armchairs.

If cirques develop on all the sides of the mountains slops,then the summit of the mountain looks like a horn.This is called horn.Matterhorn in the Alps along the border of Italy and Switzerland in Europe is the world famous example of horn.
