Question

Which formations are created by wind deposition? Check all that apply.

spits
deltas
loess hills
kettle lakes
sand dunes

Answer 1

Loess

Hills

Sand dunes

This is why:

Loess is made of silt that were wind blown from vertical cliffs.

Sand dunes are basically hills of sand. They form when wind is impeded by a rock and it drops some of the sand as it hits the rock. Slowly the deposited sand builds up to form bigger dunes.

Hills since sand dunes are hills also, this is also considered a formation made by wind deposition.

Answer 2

Wind deposition

Explanation:

Loess hills and sand dunes are the formations which are created by wind deposition

• In wind deposition wind slows down it drops the sediment it's carrying, this often happens when the wind has to move over or around an obstacle
• A rock or tree may cause wind to slow down.;as the wind slows, it deposits the largest particles first

Loess hills

• Loess is a wind-deposited silt (often including some sand and clay) composed predominantly of closely packed grains of quartz,these deposits are porous, lightweight, and easily eroded
• They are vulnerable to collapse when wet yet are quite cohesive when dry, and they exhibit sheer, nearly vertical faces that tend to form slabs, columns, and vertical tunnels or pipes as they erode
• As unusual as these hills appear, loess itself is not a rare or unusual material

Sand dunes

• When the wind deposits sand, it forms small hills,these hills are called sand dunes
• For sand dunes to form, there must be plenty of sand and wind
• Sand dunes are found mainly in deserts and on beaches
• The obstacle causes the wind to slow down,the wind then drops some of its sand
• As more sand is deposited, the dune gets bigger
• The dune becomes the obstacle that slows the wind which causes more sand to drop and further the hill takes on the typical shape of a sand dune
