Dec 20, 2014 · This document defines and describes the main types of weathering processes that occur at the Earth's surface: mechanical, chemical, and biological. Mechanical weathering involves physical breakdown through processes like frost wedging and abrasion without changing the rock's chemical composition.
Power plants and cars produce gases such as sulfur dioxide and nitric oxide. Makes rainwater more acidic. Breaks down calcite, limestone and marble. Examples: More acidic acid rain - human caused....
Types of Mechanical Weathering Frost action or Ice Wedging: Water takes up about 10% more space when it freezes. This expansion puts great pressure on the walls of a container. Water held in the cracks of rocks wedges the rock apart when it freezes.
