Erosion

Erosion and weathering are the gradual wearing down and carving away of the Earth's minerals. Here are the many ways our crust is naturally eroded:

Wind constantly wears away rock in dry areas. Lichens and other chemicals get into rocks to cause chemical weathering Water, sand and wind can cause physical weathering.When the water freezes, cracks are widened and rocks are broken apart
