Difference between weathering and erosion

Weathering is the change of appearance or texture of something by long exposure to the air and erosion is the process of eroding by wind, water, or ice.

Difference between mechanical weathering and chemical weathering

Mechanical weathering is the various weathering processes that cause physical disintegration of exposed rock and chemical weathering is the various weathering processes that cause exposed rock to undergo chemical decomposition.

Types of mechanical weathering

Abrasion, freezing and thawing,heating and cooling, animal actions, and plant growth.

Organic component of soil, formed by the decomposition of leaves and other plant material.

Types of chemical weathering

Acid rain, oxygen,carbon dioxide, water, living organisms.

Horizon A, horizon B, Horizon C.

The upper, outermost layer of soil, usually the top 2 inches to 8 inches. It has the highest concentration of organic matter and microorganisms and is where most of the Earth's biological soil activity occurs.

What is the definition of Horizon B?

The layer of soil under the topsoil on the surface of the ground. Like topsoil it is composed of a variable mixture of small particles such as sand, silt and clay, but it lacks the organic matter and humus content of topsoil.

To drain away from soil, ash, or similar material by the action of percolating liquid, esp. rainwater.

The process by which soil and rock are removed from the Earth's surface by processes such as wind or water flow, and then transported and deposited in other locations.

The breaking down of rocks, soil and minerals as well as artificial materials through contact with the Earth's atmosphere

Is the unconsolidated material underlying the solum (A and B horizons). It may or may not be the same as the parent material from which the solum formed.

Is consolidated rock underlying the surface of a planet, usually it is Earth. Above the bedrock is usually an area of broken and weathered unconsolidated rock in the basal subsoil.

The definition of chemical weathering

The erosion or disintegration of rocks, building materials and other things caused by chemical reactions.

What is mechanical weathering?

The class of processes that causes the disintegration of rocks without chemical change.
