What is a Medial moraine?

Answer 1

Moraine are the rock and soil debris deposited on the surface of a glacier by avalanches and landslips.

Those at the edges (the first formed) are Lateral moraine.

Those at the terminus of the glacier are Terminal moraine.

Where two glaciers join, then their lateral moraines join to become a Medial moraine, i.e. 'middle'.

The moraine overburden lodged towards the head of a glacier, tends to slip down the schrunds and is a major erosive component in the abrasive action.

Where the glacier travels over a step in its bed, an ice-fall is created, marked by a crevasse jumble, and into this much other moraine is embedded into the traveling glacier.

It is remarkable to realize that most of the cross-section of the U-shaped of a glacier's valley has been removed by abrasion - converted into rock flour.

Answer 2

A medial moraine is a type of glacier moraine that forms in the middle of a glacier where two lateral moraines merge. It consists of rock and debris that have been plucked and fallen onto the ice surface from the valley walls. Medial moraines are deposited in a linear ridge down the center of the glacier as the glacier flows and carries the debris along with it.

Answer 3

It is the accumulated earth and stones deposited by a glacier.

Answer 4

The ridge of till at the farthest point reached by a glacier.
