Water Changes Earths landforms by picking up and moving weathered rock.
Moving water is the major cause of weathering and erosion.
Two things that can cause a landslide is rain and gravity.
Mountain building is a slow change to earth’s land.

Volcanoes can build a new landform called islands.
Heat and pressure that build up in melted rock is a volcanic eruption.
A place where rocks breaks and slips is called a fault
