1
Q

Igneous rocks

A

Basalt, granite

2
Q

Sedimentary rock

A

Clay, sand, limestone

3
Q

Metamorphic rocks

A

They are usually resistant to weathering and erosion and are therefore very hard-wearing.

4
Q

Igneous rocks formation

A

formed by magma from the molten interior of the Earth. When magma erupts it cools to form volcanic landforms. If magma cools inside the Earth it forms intrusive rock, which may later be exposed by erosion and weathering

5
Q

Granite formation

A

It forms when it cools at a much slower pace.

6
Q

Carboniferous limestone

A

It will cool at a much quicker pace

7
Q

Chalk

A

A much softer rock than others and is mostly found on cliff sides such as the dover cliff side

8
Q

Active volcanoes

A

They are made when the plates fold together and then the active volcanoes will make metamorphic and igneous rock which is what the uplands area is filled with.

9
Q

Glacial deposition

A

When the glacier picks up eroded sediment it will put down the valley at the end.

10
Q

Sedimentary in the lowland

A

It is because of all the eroded rocks that had been in the glaciers, meaning when the glacier melt water will transport the sedimentary rock to the lowland areas

11
Q

Scarps

A

When glaciers erode away the area and creating hills while they are eroding it.

12
Q

Slate

A

Originates from chalk, so it is a harder version of chalk.

13
Q

Vale

A

In southern england, vales commonly occur between the escarpment slope formations

14
Q

Igneous rock age

A

250 to 450 million years old

15
Q

Sedimentary rock age

A

0 to 250 million years old
