Question 1

what colour is chalk

Answer 1

white

Question 2

what is an example of a igneous rock

Answer 2

granite

Question 3

an example of an upland area

Answer 3

north-west Scotland

Question 4

state one example of a sedimentary rock

Answer 4

chalk/ limestone/ sandstone

Question 5

one characteristic of a sedimentary rock

Answer 5

layered structure

Question 6

where are areas of granite found

Answer 6

the north - Scotland

Question 7

one characteristic of an igneous rock

Answer 7

formed from cooling / hard / permeable / more resistant to erosion

Question 8

state a weathering process that effects landscapes

Answer 8

chemical weathering / biological weathering / solution / hydrolysis

Question 9

why is a stream created at the bottom of an escarpment

Answer 9

water flows through permeable chalk and comes to the surface when it reaches the impermeable clay = causing a spring

Question 10

explain one impact of glaciation on the landscape of the UK

Answer 10

creation of U-Shaped valleys from glaciers in upland areas eroding pre-existing landscapes

Question 11

explain one difference between the climates in upland areas and lowland areas

Answer 11

uplands are wetter than lowlands due to relief rainfall

temperatures decline with altitude so colder in the uplands because as air rises its expands and cools

rainfalls increases with altitude because as air rises it cools which leads to condensation and increased rainfall

Question 12

explain one way in which weathering affects slopes

Answer 12

weathering breaks down rocks into smaller fragments which will slide downslope

water reacts with minerals in rocks decomposing it so it moves downslope

Question 13

explain one wain which glaciation has affected the physical landscape

Answer 13

moving ice has eroded pre-existing valleys by widening them and deepening them through glacial abrasion and plucking creating u-shaped valleys

Question 14

explain one way in which forestry can affect the landscape

Answer 14

cutting down large areas of forest reduces biodiversity of landscape

planting of large areas of forest can make the landscape look very similar and bland

Question 15

explain one reason why areas of igneous rocks are usually upland

Answer 15

igneous rocks are more resistant rocks which means they are less easily eroded

igneous rocks are hard which means less easily eroded

formed by volcanoes which erode very slowly

Question 16

define the term relict glacial landscape

Answer 16

a landscape which USED to have glacial processes/glaciers

Question 17

name one type of mechanical weathering process that operates on glacial landscape

Answer 17

freeze-thaw
