Name the types of moraines
Answers
Answer:
Moraines are divided into four main categories:-
1) lateral moraines,
2) medial moraines,
3) supraglacial moraines, and
4) terminal moraines.
LATERAL MORINE:-
A lateral moraine forms along the sides of a glacier. As the glacier scrapes along, it tears off rock and soil from both sides of its path.
Lateral moraines are usually found in matching ridges on either side of the glacier.
The glacier pushes material up the sides of the valley at about the same time, so lateral moraines usually have similar heights.
MEDIAL MORINE:-
A medial moraine is found on top of and inside an existing glacier.
Medial moraines are formed when two glaciers meet. Two lateral moraines from the different glaciers are pushed together.
This material forms one line of rocks and dirt in the middle of the new, bigger glacier.
SUPRAGLACIAL MORINE:-
A supraglacial moraine is material on the surface of a glacier.
Lateral and medial moraines can be supraglacial moraines. Supraglacial moraines are made up of rocks and earth that have fallen on the glacier from the surrounding landscape.
Dust and dirt left by wind and rain become part of supraglacial moraines. Sometimes the supraglacial moraine is so heavy, it blocks the view of the ice river underneath.
TERMINAL MORINE :-
A terminal moraine is also sometimes called an end moraine.
It forms at the very end of a glacier, telling scientists today important information about the glacier and how it moved.
At a terminal moraine, all the debris that was scooped up and pushed to the front of the glacier is deposited as a large clump of rocks, soil, and sediment.
