Erosion is the process of wearing away and transporting material, like soil, rock, or sediment, by forces like wind, water, or ice. It breaks down and removes material from one location.

Deposition is the process of dropping or settling that eroded material in a new location. It builds up and adds material to a new location.

Think of it like this:

* Erosion is like a bulldozer that scoops up dirt and moves it.

* Deposition is like the dump truck that drops off the dirt at a new location.

Here's a simple analogy:

* Erosion is like waves eroding a coastline.

* Deposition is like the beach forming from the sand deposited by those waves.

Erosion and deposition work together to reshape the Earth's surface over time.
