Breaking Down of Rocks

Weathering is the breaking down and dissolving of rocks and minerals. Weathering changes the earth's surface. It changes rocks and all sorts of things. Weathering affects the shape and  surfaces of other things. Weathering affects rocks underground by water trickling into the ground 200 m down. Chemical weathering is when the gasses dissolve the rain. Weak acids corrode rocks such as limestone.  Physical weathering happens when a rock has a crack in it and it freezes and it makes the rock's crack expand and then crack in half. The longer the rock has been exposed the quicker it is weathers. Weathering can effect homes.  If you live on a mountain and something is weathering around you, then your house might fall off of the mountain.       WATCH THE VIDEO BELOW.

This will give you a little more about chemical weathering and physical.
