1

T or F mountain slopes have more fertile soil than river valleys

False river valleys are more fertile

2

T or F dunes form where wind is strong and soil is wet

False where soil is dry

3

T or F wind and water are powerful agents that change earth

True

4

T or F fiat land is more prone to mass wasting than billed land

False - hilled land is more prone

5

T or F heavier particles travel more than lighter ones when moved by wind and water

False- lighter travel further

6

Soil scooped out by wind is ______

Deflation hollows

7

Large mass of moving ice is _____

Glacier

8

Removal of material by wind water or ice is _____

Erosion

9

Mound of till is _____

Moraine

10

Wearing down of rock by chemical process _____

Chemical weathering

11

Wearing down rock surface by other rocks

Abrasion

12

Surface feature of place or region ________

Topography

13

Loose layer of rock and soil _______

Regolith

14

Downhill movement

Landslide

15

Breaking down of rock by physical process ?

Mechanical weathering

16

Carbon combining with other substances?

Carbonation

17

Left behind by glaciers?

Till

18

Describe 3 processes or mechanical weathering

Ice wedging - water seeps into cracks and freezes and then expands breaking the rock
Temperature extremes- rocks expand in heat and contract in cold
Living things- trees force rocks to split

19

Describe 3 processes of chemical weathering

Hydrolysis- chemical interaction with water on rocks
Carbonation - carbonic acid and other minerals form substances
Oxidation - chemicals combing with oxygen (rust)

20

3 factors that determine how fast rocks weather

Type of rock - sedimentary softer than igneous and metamorphic
Surface area- smaller rocks weather faster
Climate - higher rainfall means faster weathering

21

3 forces lead to erosion of material

Wave action
Glacier ice
Avalanches

22

*Flood control question *

Pavement

23

Landslide question

All of above

24

Most easily weathered

Sedimentary

25

Not a force that makes erosion

Year round coldness

26

Water responsible for mechanical weathering

Temperature

27

Essay how would you address cottage building question

Eroding dunes isn't good for the earth and building on sand isn't good for cottages

28

Cutting down tree essay question

Mass wasting would affect the houses and buildings more than trees

29

True
