In glacial erosion by abrasion, a glacier scrapes and wears away at the underlying rock as it flows over it, carrying coarse particles like rocks and boulders. The abrasive action of these particles and the glacier's movement carves grooves and striations into the bedrock, shaping the landscape over time.
Cirques are bowl-shaped depressions formed by glacial erosion at the head of a glacier. Arêtes are narrow ridges that separate two adjacent glacial valleys. Roche moutonnées are glacier-smoothed bedrock outcrops with a gentle up-glacier slope and a steep down-glacier slope.
A cirque is a landform created by glacial erosion. It is a bowl-shaped depression with steep walls located at the head of a glacier.
Terminal moraines are not formed due to erosion but rather deposition. They are ridges of glacial till that mark the farthest advance of a glacier and are deposited as the glacier retreats. Erosion by the glacier does contribute to the material found in terminal moraines, but the feature itself is primarily a result of deposition.
Glacial erosion typically produces well-sorted sediment known as glacial till. This sediment is composed of a wide range of particle sizes, from clay to boulders, due to the mixing and transport by the glacier. Glacial till is often unsorted and can be deposited directly by the glacier or as moraines when the glacier retreats.
Glacier erosion is the process by which glaciers wear away rocks and soil as they move, sculpting the landscape through processes like plucking and abrasion. Glacial deposition is when glaciers deposit the material they have eroded elsewhere, forming features like moraines, drumlins, and eskers. In essence, erosion involves the removal of material, while deposition involves the accumulation of material.
Glacial erosion requires movement. Thus, glacial erosion begins as soon as the glacier starts moving.

A cirque is a glacier feature that is shaped by erosion. It is a bowl-shaped hollow at the head of a glacier that forms from the glacier's erosive action on the surrounding rock.

A drumlin is a land-form from glacial deposition, which was once eroded. It is formed both by erosion and deposition. A drumlin is formed when moraine deposited by a retreating glacier is subsequently reshaped by the returning glacier the following year or after the glacial interval with caused the glacier to retreat in the first place.
if there is any glacier in warm places, highly possibly.
A moraine is a landform created by glacial deposition, not erosion. As a glacier moves, it picks up rocks and debris which are deposited as the glacier retreats, forming moraines.
Plucking is a form of glacial erosion where a glacier will pick up and carry pieces of bedrock as it moves. This process occurs when meltwater at the base of the glacier freezes onto the rock, and as the glacier moves, it pulls these frozen rock pieces along, causing erosion. Plucking can result in the removal and transportation of large rock fragments by glaciers.
