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
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?
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
The Emirates Palace Hotel in Abu Dhabi is made of Limestone, which is an example of this type of rock.
Limestone is a form of sedimentary rock.
400
What is biological weathering?
Biological Weathering is the weathering of rocks by plants (tree roots) and animals.
400
How do you change sedimentary rocks into igneous rocks?
Through melting and cooling
500
Which type of rock is Jebel Hafeet made of?
Sedimentary Rock
500
How are sediments turned into sedimentary rocks?
Through the compaction and cementation of sediments
500
The Sheikh Zayed Grand Mosque is made of Marble, which is an example of this type of rock.
Marble is a form of Metamorphic Rock.
500
How does physical weathering differ from chemical weathering?
Physical Weathering is the breaking of rocks is the changing of a rock's size or shape (staysw the same rock), while Chemical weathering changes the rock's composition into something different.

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