WEATHERING AND SOIL FORMATION!

Chapter 10By: Paula Tatum

Weathering Weathering is the breakdown of rock into

smaller and smaller pieces.

Mechanical Weathering Mechanical Weathering is simply the

breakdown of rock into smaller pieces by physical means.

Chemical Weathering Chemaical weathering is the chemaical

breakdown of rocks and minerals into new substances.

Abrasion Abrasion is the action of rock and

sediment grinding against each other and wearing away exposed surfaces

Acid Precipitation Acid Precipitation is precipitation the

contains acid to air pollution.

Oxidation Oxidation is a chemaical reaction in

which an element such as iron, combines with oxygen to form an oxide.

Differential Weathering Differential Weathering is a process by

which softer, less weather-resistant rocks wear away, leaving harder, more weather-resistant rock behind.

Soil Soil is a loose mixture of small mineral

fragments and organic material.

Bedrock Bedrock is the layer of rock beneath soil.

Parent rock Parent rock is the rock that is the source

of soil.

Humus Humus is soils that contain very small

particles of decayed plant and animal material.

Topsoil Topsoil is the top layer of soil.

Leaching Leaching is the process by which

rainwater dissolves and carries away the minerals and nutrients in topsoil.

Soil conservation Soil conservation consists of the various

methods by which humans take care of the soil.

Erosion Erosion is the process by which wind and

water transport soil and sediment from one location to another.
