12 What do we call the sediment that is carried in a river?
Load Till Sediment Dust 30 Seconds Remaining 30

13 Freezing and thawing can weather rocks through a process called:
Deposition Ice wedging Deflation Plucking 30 Seconds Remaining 30

14 A rock containing iron becomes soft and crumbly as it begins to rust
A rock containing iron becomes soft and crumbly as it begins to rust. It has probably been chemically weathered by: Plants Carbon dioxide Oxygen Acid Rain 29 Seconds Remaining 30

15 What do we call the solid layer of rock beneath all soil horizons?
Bedrock Gravel Subsoil Granite 30 30 Seconds Remaining 30

16 The decayed organic material found in topsoil is referred to as:
Silt Litter Humus Clay 30 30 Seconds Remaining 30 10

17 Why is soil considered to be a valuable resource?
It is important to all living things on land. It contains sand and gravel. It protects Earth’s crust. All of the above. 30 30 30 Seconds Remaining

18 What event occurred in the 1930s and was responsible for the creation of soil conservation techniques? The great depression WW II The advent of the motorized plow The Dust Bowl 30 Seconds Remaining 30

19 What is the order of Earth’s destructive forces?

20 Which soil particle is the largest?
Gravel Sand Clay Silt 30 30 Seconds Remaining 30 10

21 True or False: Weathering is the process by which sediment is laid down in a new location.
30 Seconds Remaining 10 Seconds Remaining 30 30

22 Landslides, Mudflows, Creep, and Slump are all examples of what force?
runoff soil formation deflation mass movement 30 Seconds Remaining 30

23 Glaciers can only form when:
More snow falls than melts There is an ice age The amount of snow exceeds the amount of rain. None of the above. 30 30

24 What do we call the water that moves over Earth’s surface?
Runoff Watershed Groundwater Ice 30 Seconds Remaining 30
