How do erosion and deposition continually work togther to build up and wear down earth's surface?
Erosion is consistantly working through water, erosion, gravity, and ice. Erosion is when these sediments get picked up by one or more of these forces and moved. When these sediments are put in an area, that is deposition, when this orccurs for a while, deposition can create landforms like hills and mountains. Together, these wear down and build up earth's surface.
