Earth Science
True or False? Waves are the major force of erosion along coasts.
True
True or false? All sediment picked up by wind eventually falls to the ground.
True.
What part of water is affected by wave in deep water.
Water is only effected near the surface.
When does wind-carried sediment go to the ground?
When wind speed slows down or sediment meets an obstacle.
List two types of deposits formed by wind erosion and deposition.
1.) Sand dunes 2.) Loess Deposits
True or False? 1.) It comes from wind. 2.) It moves water particles up and down. 3.) It moves water particles forward. 4.) It moves across the water.
1.) True 2.) False 3.) False 4.) False
What is true about wave approaching land? 1.) It begins to drag on the bottom. 2.) It encounters more friction. 3.) It speeds up. 4.) It moves the water toward the land.
1.) True 2.) False 3.) False 4.) True
True or False about deflation? 1.) It is the main way wind causes erosion. 2.) It usually has a great effect on the land. 3.) It can create blowouts. 4.) It can create desert pavement.
1.) True 2.) False 3.) True 4.) True
True or false about abrasion? 1.) It can polish rock. 2.) It is caused by wind-carried sand. 3.) It causes most desert landforms. 4.) It causes most erosion.
1.) True 2.) True 3.) False 4.) False
A deposit of wind-blown sand is...
A sand dune
True or false? Wind alone is the strongest agent of erosion.
False.
(Difference) Sand Dunes=? (Difference) Loess Deposits=? (Similarity between two)=?
Sand Dunes= Coarse Sand Loess Deposits= Fine sediments Similarity= Formed from wind
Why is wind effective at causing erosion in deserts?
There are no plants that grow there. The dry, light sand is more easily carried by wind.
