weathering

the breaking down of rocks and minerals on earth's surface. Often due to physical and chemical processes

• Weathering

• Erosion

• Earth System

• Surface Process

Involves a reaction; a new substance is created

• physical weathering

• chemical weathering

• physical weathering: abrasion

• chemical weathering: reaction with acid

• chemical weathering: oxidation

• physical weathering: ice/frost wedging

The mechanical breakdown of rocks into smaller pieces that are caused by natural processes that do not change the chemical composition. 

• MECHANICAL WEATHERING (PHYSICAL)

• CHEMICAL WEATHERING

• ABRASION

• NONE FO THE ABOVE

A chemical reaction in which a material combines with oxygen to form a new material; in geology, oxidation is a form of chemical weathering.

• OXIDATION

• WEATHERING

• CHEMICAL WEATHERING

• NONE OF THE ABOVE

Types of Weathering

• mechanical

• mental

• chemical

• auto

Roots can grow within the cracks of rocks

• animal action

• plant growth

• abrasion

• acid perception

Weathering caused by burrowing and digging, exposing rock and soil to the surface

• plant growth

• wind abrasion

• animal action

• water abrasion

Small rock particles picked up by the win and blown at other rocks, causing them to break down is ______ abrasion.

Rocks picked up and moved by water can bump into other rocks, causing them to break down is called ___ abrasion.
