Answer 1

${\huge{\bf{\red{Answer}}}}$

Moraines are divided into four main categories:-

• Lateral moraines

• Medial moraines

• Supraglacial moraines

• And terminal moraines

Lateral moraines - a moraine in the middle of a glacier parallel to its sides that is often formed by the union of lateral moraines when two glaciers coalesce.

Medial moraines - A medial moraines is found in top of and inside an existing glacier, medial moraines are formed when two glacier meet.

Supraglacial moraines - 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.

Terminal moraines - A terminal, or end, moraine consists of a ridgelike accumulation of glacial debris pushed forward by the leading glacial snout and dumped at the outermost edge of any given ice advance. It curves convexly down the valley and may extend up the sides as lateral moraines.
