Question 7(Multiple Choice Worth 3 points) Minerals form during I. crystallization in magma. II. deposition from solution III. lithification in rocks I only Il only I and Il only I, II, and lIl

Answer 1

Answer:

I and Il only,  crystallization in magma and dissolved in water.

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.
