Explain the following: Wind erosion – abrasion and deflation, Water Erosion?

I have a SOSE project due on Tuesday and am having trouble finding simple definitions for the above. We also need to know what blowouts, badlands, stony deserts, gibber plains, deserts, Mesas, ventifacts, buttes, alluvial fans, sand dunes, bajadas, barchans and honeycomb rocks are. Can someone give me some simple definitions for these? you don't have to answer them all.
