What Are the Four Causes of Mechanical Weathering? | Sciencing

Apr 24, 2017 . Abrasion weathering is caused by the abrading or grinding together of rock particles. As rocks weather into smaller pieces, they are moved around by wind and water and rub against each other, grinding and abrading off more pieces of rock. For instance, small wind-blown rock particles have the same.
