im doing an essay on erosions caused by wind. what are some helpful facts and main ideas that i shud include?

Answer 1

No water involved.

No chemical erosion.

The wind in and of itself is not causing the erosion. It is the small particles of sand and grit propelled by the wind impacting on other rocks that cause them to erode by impact and friction.

Some rocks erode more easily in places and others are more resistant. This is what gives some rocks a "sculpted" look.

Most deserts are the result of wind erosion.

The Antarctic ice mass experiences wind erosion.

Answer 2

Make sure you explain the difference between weathering (the process of breaking down the rocks and minerals) and the erosion (transport of material)
Talk about sand dunes: their formation, shape etc. Google Earth can give you some great sand dune images in Sahara, South Australia and elsewhere.
I think the only erosional process that can transport material uphill: rest rely on gravity/slope

Answer 3

If you are talking about erosion caused by wind; don't forget that waves are caused by the wind blowing across the ocean, and wave erosion is therefore caused indirectly by wind.
