Question
What is the name for a bowl-shaped hollow structure carved by glacier in the mountain?
- Arete
- Cirques
- Horn
- Moraine
Hint:
Also called armchair shaped valley.
The correct answer is: Cirques
The correct option is b) Cirques.
- Glacial cirques, locally known as collies, are a feature of extensive erosion common to many mountainous regions.
- Classical curls take the form of armchair-shaped troughs with steep head walls (often culminating in sharp crests or ridges) and gentle slopes or sharply depressed valley floors.
- In active glacial landforms, the cirque is an important catchment area for snow cover.
- They may host small Karl glaciers trapped in bedrock cavities or serve as headwaters for larger valley glaciers.

______ is the shaping of the land present below the moving glacier.
The correct option is B)Glacial erosion.
Glacial erosion involves the removal and transport of bedrock and sediments through three major processes: quarrying (picking), abrasion and meltwater. Mining involves two separate processes: crushing the bedrock beneath the glacier and carrying the crushed rock along. Erosion by glacial meltwater under glaciers is the result of mechanical or chemical processes.

_________ causes weathering of rocks in glacier.
The correct option is b)Ice.
Ice wedges are defined by the physical weathering of rock, where the surface within rock cracks fills with water, freezes, and eventually expands. Widening cracks and build-up of pressure within the rock cause it to expand and fracture. Ice wedging is also called frost wedging.
