Is erosion deeper than a ulcer?
No, erosion is a surface-level wearing away of material, whereas an ulcer is a hole or lesion that penetrates deeper into tissue. Ulcers can affect various parts of the body, such as the stomach lining or skin, and are typically more severe than erosion.
What do rocks look like after erosion?
Crumbled and smaller than before. It might depend on what type of erosion. There's onion skin (clues in the name), acid rain (makes a mess of rock after many years), and freezing (When a crack in a rock is filled with water that freezes and then melts repeatedly). There's also biological erosion caused by burrowing animals and plant seeds.
How does sun cause erosion?
In arid or dry climates like deserts, the sun heats up rocks in the day. So the rock expands. At night it cools down so the rock contracts. The constant expanding and contracting weakens the rock and over time the outer layer peels of, hence this process is known as onion skin erosion or exfoliation.
Is the earth surface smooth?
