Rock Types
Which type of rock forms from layers of sediment?
Sedimentary rock
What is the rock cycle?
The processes that change rocks from one type to another
What is the breaking down of rock called?
Weathering
What is melted rock below Earth's surface called?
Magma
Which type of rock forms when magma or lava cools?
Igneous rock
What can weathering break rocks into?
Sediment
What do we call small pieces of broken-down rock?
Sediments
What is melted rock called when it reaches Earth's surface?
Lava
What are the three main rock types?
Sedimentary, Metamorphic, Igneous
What happens to magma when it cools?
It forms igneous rock
What is erosion?
The movement of weathered rock/sediment
What happens to sediment during compaction?
It is pressed/squashed together
Which type of rock forms when existing rock is changed by heat and pressure?
Metamorphic rock
What can happen to rock when it experiences heat and pressure?
It can become metamorphic rock
Name one thing that can move sediment.
Water, wind, ice or gravity
What two things can change existing rock into metamorphic rock?
Heat and pressure
What type of rock is basalt
Igneous rock
Can any of the three rock types become another type?
Yes
What two processes help turn sediment into sedimentary rock?
Compaction and cementation
Put these in the correct order:
sedimentary rock → sediment → weathering.
Sedimentary rock → weathering → sediment
