Topic 9/10 Review. WED

When wind and running water gradually decrease in velocity, the transported sediments are deposited...

• over a period of time, and are sorted by size and density

• over a period of time, and are unsorted

• all at once, and are sorted by size and density

• all at once, and are unsorted

Which cross section best represents the pattern of sediments deposited on the bottom of a lake as velocity of the stream entering the lake steadily decreased?

• 
• 
• 
• 

This picture is an above view of horizontal sorting into a lake. A river most likely is flowing into the lake nearest to which location?

• A

• B

• C

• D

The natural chemical or physical processes that breaks down rock on Earth's surface.

• weathering
• erosion
• deposition
• jackhammering

The process by which water, ice, wind or gravity moves weathered rock and soil from one place to another.

• weathering
• erosion
• deposition
• dumptruck

This type of weathering occurs when rock is physically broken down into smaller pieces of rock.

• mechanical weathering
• chemical weathering
• erosion weathering
• deposition

This type of weathering occurs when rocks weaken then break down due to chemical changes in the composition of the rock.

• mechanical weathering
• chemical weathering
• erosion weathering
• deposition

These rocks were broken apart from the continuous freeze/thaw of water in the cracks of the rocks. This is an example of:

• ice wedging
• acid rain
• permeability
• abrasion

The formation of stalactites and stalagmites in a cave as water mixed with carbon dioxide creates carbonic acid, which dissolves away the limestone, is an example of:

• mechanical weathering
• chemical weathering

What happens when weathering and erosion work together?

• New Mountains are created
• The climate changes overnight
• Metal objects become rusty
• They change the Earth's surface
