Question 2

What is magma?

Accepted Answer

Molten rock inside Earth.

Question 3

What process breaks rocks into smaller pieces?

Accepted Answer

Weathering.

Question 4

What role does the Sun play in the rock cycle?

Accepted Answer

It provides energy that drives weathering and erosion.

Question 5

How does igneous rock form?

Accepted Answer

When magma or lava cools and hardens.

Question 6

What process moves sediment from one place to another?

Accepted Answer

Erosion.

Question 7

What is deposition?

Accepted Answer

When sediment settles in layers.

Question 8

How do metamorphic rocks form?

Accepted Answer

When rocks experience heat and pressure without melting.

Question 9

What two processes turn sediment into sedimentary rock?

Accepted Answer

Compaction and cementation.

Question 10

What happens if rock melts?

Accepted Answer

It becomes magma.

Question 11

What process changes rock without melting it?

Accepted Answer

Heat and pressure.

Question 12

How does plate movement help drive the rock cycle?

Accepted Answer

It moves and recycles rocks through melting, pressure, and mountain building.

Question 13

What can form when tectonic plates collide?

Accepted Answer

Mountains.

Question 14

How does sedimentary rock form?

Accepted Answer

When sediment is compacted and cemented together.

Question 15

What must happen before igneous rock forms?

Accepted Answer

Melting and cooling.

Question 16

What causes weathering?

Accepted Answer

Energy from the Sun.

Question 17

What does Earth's interior heat help with?

Accepted Answer

It helps move tectonic plates.

Question 18

What is cementation?

Accepted Answer

When minerals glue sediment together.

Question 19

What can happen to any rock type over long periods?

Accepted Answer

It can change into another type.

Question 20

What is compaction?

Accepted Answer

When layers of sediment are squeezed together.

Question 21

What is an example of the rock cycle in action?

Accepted Answer

A river.

Question 22

What is lava?

Accepted Answer

Molten rock on Earth's surface.

Question 23

What process helps create magma?

Accepted Answer

Plate movement.

Question 24

What happens to the total amount of rock material on Earth?

Accepted Answer

It stays about the same because it is recycled.

Question 25

What happens to rock material during the rock cycle?

Accepted Answer

It is constantly recycled and reused.

Question 26

What is molten rock inside Earth called?

Accepted Answer

Magma.

Question 27

What is breaking rock into smaller pieces called?

Accepted Answer

Weathering.

Question 28

What is the movement of Earth's crustal plates called?

Accepted Answer

Plate tectonics.

Question 29

What is the correct sequence for how sediment becomes sedimentary rock?

Accepted Answer

Weathering → Erosion → Deposition → Compaction → Cementation.

Question 30

When sediment settles in layers, it is called:

Accepted Answer

Deposition

Question 31

How does plate movement help drive the rock cycle?

Accepted Answer

It moves and recycles rocks through melting, pressure, and mountain building.
