<u>I and Il only, crystallization in magma and dissolved in water</u>.
Explanation:
Most of the minerals are formed due to the crystallization of lava or molten matter in due course of time when it slowly cools in contact with the land surface as in rapid cooling there is no time for the formation of crystals.
Minerals are then formed from the evaporated of the solution a mix of substances dissolved in another. For example deposits of table salts.
If the magma erupts to the surface and becomes a lava it tends to cool quickly and small crystals are formed. Depending upon the number of gases and chemical composition of lava.
Dune deflation hollows are where wind has removed sand down to a level where a layer of particles too heavy for the wind to move (an armoured surface) stabilises the sand and prevents the surface being lowered further.
A crevasse is a deep, wedge-shaped opening in a moving mass of ice called a glacier. Crevasses usually form in the top 50 meters (160 feet) of a glacier, where the ice is brittle.
a mass of rocks and sediment carried down and deposited by a glacier, typically as ridges at its edges or extremity.
