4.1 Geology Uk

Question 1

Igneous rocks

Answer 1

Basalt, granite

Question 2

Sedimentary rock

Answer 2

Clay, sand, limestone

Question 3

Metamorphic rocks

Answer 3

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

Question 4

Igneous rocks formation

Answer 4

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

Question 5

Granite formation

Answer 5

It forms when it cools at a much slower pace.

Question 6

Carboniferous limestone

Answer 6

It will cool at a much quicker pace

Question 7

Chalk

Answer 7

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

Question 8

Active volcanoes

Answer 8

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.

Question 9

Glacial deposition

Answer 9

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

Question 10

Sedimentary in the lowland

Answer 10

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

Question 11

Scarps

Answer 11

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

Question 12

Slate

Answer 12

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

Question 13

Vale

Answer 13

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

Question 14

Igneous rock age

Answer 14

250 to 450 million years old

Question 15

Sedimentary rock age

Answer 15

0 to 250 million years old
