(Q017) A glacier can have only one of which of the following types of moraines?Group of answer choiceslateralendmedialterminal

A glacier can only have one terminal moraine.

Here's why:

1. Lateral Moraines: These are formed along the sides of a glacier. As a glacier moves, it erodes the sides of the valley which it occupies, and the debris is carried along the sides of the glacier. A glacier can have two lateral moraines, one on each side.

2. End Moraines: These are also known as terminal moraines and mark the furthest point reached by a glacier. They are formed from the debris that was pushed forward by the glacier before it started to recede. A glacier can only have one end or terminal moraine.

3. Medial Moraines: These are formed when two glaciers merge, and the lateral moraines of each join to form a line of debris down the middle of the resulting glacier. A glacier can have multiple medial moraines, depending on how many glaciers have merged.

So, out of the options given, a glacier can only have one terminal (or end) moraine.
