1. sand dunes play an important part in protecting the coastline.
2. one way to protect dunes from further damage is to build up the dunes with vegetation.
3. sand dunes are naturally occurring dynamic coastal features which are formed by the accumulation of wind blown sand. when sand dunes are damaged from storms or human activity they can be repaired or restored.
4.if sand dunes were in a area destroyed the sand would cause a island to form because it the other island was destroyed leaving all the sand in one place.

I’m just thinking something from the top of my head so it may not be much so if weathering didn’t exist, there wouldn’t be anything to break up earth’s crust naturally. so by assumptions, the rocks on earth would be larger than they actually are since there’s nothing to break them up into smaller parts.overall, i’m not really sure, but all i know is that it’ll mess up the rock cycle that we have now.hoped this .

Answer: wait ?
