How Does Rock Erosion Affect the Earth’s Features?
Erosion is the process that shaped all Earth’s landforms that are here today. Because of erosion, we have landforms from canyons in the desert to steep cliffs along the ocean. During erosion, the pieces that break off of the rock move from one place to another. They move by natural agencies such as ice, water, wind or gravity.
Erosion and weathering are both part of the rock cycle, and normally occur at the same time. But, you can tell the difference between the two. Erosion transports the rocks to another location. There is no movement involved in weathering.
How the rock pieces move from one place to another is called transport. An example of this would be pebbles rolling along the shore. When they are left at a new location, we call that deposition.
Ways in Which Rock Can be Eroded
There are many ways erosion can occur in rock, one of the most popular being with water. An example of this would be rain seeping into cracks in a rock during the day. When night comes, the temperatures drop so low that the water freezes and becomes ice. The ice is stronger than the rock and splits it! The next day, the sun comes out and the ice melts. Water erosion then sends the rock remains somewhere else.
