The Rock Cycle
100
What are the three types of rocks found on Earth?
Sedimentary, Metamorphic and Igneous Rocks
100
Rocks are broken into smaller sediments through these two processes:
Weathering (breaking of rocks into smaller pieces) and Erosion (movement of sediments from one place to another)
100
What are sedimentary rocks used for?
They are used to make walls and bricks.
100
What is weathering?
Weathering is the breaking down of rocks into smaller fragments/pieces.
100
What is magma?
Magma is liquid rock
200
Which type of rock is made up of layers of sediments?
Sedimentary Rocks
200
Which process will turn any rock into magma?
Melting
200
What are metamorphic rocks used for?
They are used to build roofs, floors and buildings.
200
What is erosion?
Erosion is the movement of sediments from one place to another.
200
How do you change sedimentary rocks into metamorphic rocks?
By adding heat and pressure
300

Which type of rock is found around volcanoes?

Igneous Rocks

DOUBLE POINTS:

What is the difference between igneous rocks formed on the surface and those formed underground?

300
How are metamorphic rocks made?
By adding heat and pressure
300
What are igneous rocks used for?
They are used to build roads, statues and kitchen worktops.
300
What natural factors can cause the weathering and erosion of rocks?
Water, Wind, Ice
300
How can you change metamorphic rocks into sediment?
Through weathering and erosion
400

Which layer of rock is made deep underground through heat and pressure?

Metamorphic Rock

400
How are igneous rocks formed?
By the melting of rocks into magma and then cooling that magma so that it solidifies.
400

 Limestone is an example of this type of rock.

Sedimentary rock.

400

Chalk from the White Cliffs of Dover and coal are examples of this type of sedimentary rock.

Organic Sedimentary

DOUBLE POINTS: What type of organic material is coal made from?

400
How do you change sedimentary rocks into igneous rocks?
Through melting and cooling
500

Which type of rock is Granite?

Igneous Rock

DOUBLE POINTS:

Is granite formed underground or on the Earth's surface?

500
How are sediments turned into sedimentary rocks?
Through the compaction and cementation of sediments
500

Marble is an example of this type of rock.

Metamorphic Rock.

500

Fossils are formed in this type of rock

Sedimentary

500
How can igneous rocks be changed into sedimentary rocks?
Through weathering & erosion and compaction & cementation
