Question 11

Define Crystallization

Answer 11

Process which atoms are arranged to form a material with a crystal structure

Question 12

Describe how minerals form

Answer 12

Minerals can be formed as hot magma cools inside a crust

When elements and compounds that are dissolved in water and leave a solution

Question 13

Igneous rock

Answer 13

Created when magma or lava cools and crystalizes

Question 14

Sedimentary rock

Answer 14

rock material that forms where rocks are broken down into smaller pieces or dissolved in water as rocks erode or remains of plants and animals pressed together.

Question 15

Metamorphic rock

Answer 15

when an existing rock is changed by heat and pressure

Question 16

Describe the processes of the rock cycle and how one rock type becomes another

Answer 16

Rocks can become one another through processes like Erosion, deposition, heat and pressure, melting and volcanic activity
