Compare and contrast how wind and glaciers abrade rock

Wind abrades rock by sandblasting, this is the process in which wind causes the blowing of millions of grains of sand, which bumps across the surface of rocks' surface. it can also happen due to deflation, which is when wind removes the top layer of fine sediment/soil to cause desert pavement. 
Glaciers, however, abrade rock by simply using Gravity. when enough ice builds up on a slope, the ice begins to move downhill. The steeper the slope, the faster the glacier. As glaciers move forwad, the material that they picked up scratch and abrade the rock and soil underneath the glacier, which causes erosion.
Hope this helps! :)

It depends on what you believe, if you’re christian that you would have been told that the first humans were created by god and that we’re all decedent's from adam and eve but scientist say otherwise
