Solution:
1.
When rocks are broken down and crumble from repeated freezing and then thawing, it is called _________.
-
Explanation: Repeated freezing and thawing cause physical breakdown of rocks, which is a process known as

weathering
2.
_________ rock forms when magma from the inside of the Earth cools and then hardens.
-
Explanation: Magma cooling and hardening results in the formation of
igneous rock. Igneous rocks are formed from the solidification of molten material.
-
Answer:
igneous
3.
_________ rock changes because of heat and pressure, usually while it is buried deep below the Earth’s surface.
-
Explanation: Rocks that change due to heat and pressure are called
metamorphic rocks. Metamorphism refers to the transformation of existing rocks into new forms under high temperature and pressure conditions.
-
Answer:
metamorphic
4.
_________ rocks are made up of several different layers.
-
Explanation: Sedimentary rocks are formed by the accumulation and cementation of layers of sediment over time. They often have visible layering (stratification).
