Weathering is the breakdown of materials in the earths crust into sediment. Erosion is when the rock that has been broken down by weathering is carried away by water, wind, and ice.
One example of weathering is when sulfuric acid mixes with water and forms acid rain. This acid rain then erodes limestone. This type of weathering is called chemical weathering. An example of physical weathering is when wind wears away the crust of the earth.
Two examples of erosion are when the wind pushes sediment away, or when water carries debris away.
