1

What is igneous?

Made from magma eg. granite

2

What is sedimentary?

Compressed sediment eg. clay or limestone

3

What is metamorphic?

Igneous or sedimentary rock changed by heat or pressure

4

What happened to the top half of the UK during the Ice Age?

It was glaciated- ice pressed down on the landscape and eroded it in distinctive ways

5

What happened to the bottom half of the UK during the Ice Age?

It was not covered in ice sheets but it was heavily influenced by glacial deposition

6

What is chalk like?

It is very strong and permeable so it forms cliffs when it occurs at coastlines

7

Where chalk found?

Only in lowland Britain

8

Where is clay found?

All over Britain

9

What is clay like?

It is weak and impermeable

10

What are clay landscapes like?

They are wide, flat plains with lots of lakes, streams and rivers

11

What is granite like?

It is very hard and resistant to erosion but is susceptible to chemical weathering

12

Why are granite landscapes badly drained?

Because granite is impermeable

13

What are some features of granite landscapes?

Tors- towers of granite chemically weathered into blocks

14

In lowland landscapes how has the landscapes been formed?

By the cations of rivers as the rivers have meandered and they have eroded a wide valley between low hills

15

What do the rivers transport? LL

They transport silt eroded from the chinned; sow hen there is prolonged rain they flood depositing silt to form floodplains

16

What is Stickle Torn? UL

A post glacial feature- it is where a glacier formed during the Ice Age creating a corrie

17

What does weather of rocks lead to? UL

Rock fragments breaking off and falling to the base of the cliff to form a scree slope

18

What does the high precipitation of Lake District mean? UL

There is lots of surface drainage over the impermeable rocks- lots of streams

19

What does the valley floor reveal? UL

It is flat and steep sides reveal that the U-shaped valley was created by a glacier

20

What are drainage ditches built for?

To drain water away from low-lying agriculture to allow crops to grow

21

Why have tees been cleared?

To make way for agriculture

22

What have UK upland landscapes done?

They have planted tees, often in straight rows to make forestry processes easier

23

The UK would naturally covered by deciduous woodland, why is it not?

Some UK landscapes feature conifer plantations, which have been planted for timber productions and are very distinctive

24

Why are river meanders good?

Good defensive locations

25

Where are fishing villages located?

On sites with natural harbours

26

Why are springs good?

They gave people reliable freshwater

27

What happened as settlements grew?

They took over the landscapes so now in big cities many rivers and streams run in tunnels underground
