The correct answer is:

Older glaciers have longer ice crystals than younger ones

Answer: Moraines form when glaciers pick up large rocks.

Moraines are accumulations of stones, large rocks and sediments carried and transferred by a retreating glacier. A moraine is deposited as a ridge formed at the direction parallel to the ice movement.
