Erosion Questionnaire Ms. Elliot MHS

What is Weathering?

• the process whereby these sediments are released by their transporting agents (dropped).
• the process where the sediments are transported by wind, gravity, glaciers, man, and running water.
• the breakdown of rocks into smaller pieces, called sediments.
• the water velocity increases, the particle size that the water can carry also increases, therefore the amount of erosion increases.

What are the primary types of weathering?

• Chemical and Physical
• Exfoliation and Abrasion
• Oxidation and Hydration
• Carbonation and Acidic

What is the very thin surface covering (not really a layer) called?

• O- Horizon
• A- Horizon
• B- Horizon
• C- Horizon

What is the correct definition of Transported Soils?

• soils that formed in one place and were transported to their present location by glaciers.   You can tell when the soil does not chemically match the bedrock below it. 
• soils that are located above the rocks that they formed from.  In other words, the soil chemically matches the bedrock below it, because it is a product of that rock’s weathering over time.

True or False: Deposition : the process where the sediments are transported by wind, gravity, glaciers, man, and running water.

• False
• True

What is 1 of the 5 main agents of erosion?

• Glaciers
• Technology
• Food
• Sitting Water

There are 4 basic products of weathering, that can be eroded: What is NOT one?

• Liquids
• Solid Sediments (boulders, cobbles, pebbles, sand, silt)
• Colloids/Clay Particles (not visible to your eye)
• Ions (very small electrically charged particles)

Running water can transport sediment in three ways: What is NOT a way?

• Solution
• Suspension
• Saltation
• Saluability

There are 5 ways that man can cause erosion: What is NOT one? 

• Forestry
• Strip Mining
• Construction
• Proper Farming 

What is the correct definition of Oxidation?

• oxygen combines with the elements in the rock and it reacts.
• water can dissolve away many earth materials, including certain rocks. 
• carbon dioxide dissolves in water to form carbonic acid.  This makes acid rain which chemically weathers (dissolves) rocks.  Other acids also combine with water to make acid rain.
• the breakdown of rocks and minerals into smaller pieces by chemical action.
