How water changes the earth's surface weathering ,erosion, and depisition?

I think the water changes the earth's surface by making the flood come which is how earthquake happen and with earthquake happening, the volcano will erupt.

Weathering is the process in which a canyon is made for example. The water slowly takes off chunks of rocks over years and years until a canyon is formed. Erosion is the process in which beaches are destroyed. The water comes up, takes the sand into the ocean and finally after years and years there isn't a beach anymore. 

Lacking something of the ozone layer
