Describe 3 ways abrasion occurs in nature

There are three ways of abrasion occurs in nature; the wind, waves, and gravity. Abrasion is the mechanical process of wearing away of a rock surface and the movement of the particles while transporting through the wind, waves, and gravity.

Abrasion is part of the natural process of erosion that all objects on Earth, natural or manmade undergo, Abrasion is caused in nature due to two things, Wind, Water and Ice (glaciers etc.), Gravity can be called an abrasive force but it is debatable as it self it does not do anything.
