Weathering
TYPES
Chemical
Chemical weathering is what happens when rocks are broken down and chemically altered. Learn about the different types of chemical weathering, including hydrolysis, oxidation, carbonation, acid rain and acids produced by lichens.
-
-
Physical
Physical Weathering is sometimes known as Mechanical Weathering . Physical Weathering is known of how rock break up by a natural processes.
-
Definition: The process in which rock material is broken down by the action of Physical or Chemical weathering
Agents
Water: A colorless, transparent, odorless, tasteless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.
-
Ice:Frozen water, a brittle, transparent crystalline solid.
Wind:The perceptible natural movement of the air, especially in the form of a current of air blowing from a particular direction.
Human Activity
By burning coal, and gasoline putting bad chemicals into the air which would technically eat away ar some of the rock
-
Erosion
Definition:The process by which wind, water, or gravity transports soil and sediments from one place to another.
-
Examples
The picture here shows an massive amount of sand/soil being transported by wind into the farmland this is a "deadly'' but a very good example of wind erosion
This rock has been hit with some type of erosion for a long period of time and has ended up denting and wearing away sediments from the structure.
Soil
SUBSOIL
B horizons: are commonly referred to as the subsoil. They are a zone of accumulation where rain water percolating through the soil has leached material from above and it has precipitated within the B horizons or the material may have weathered in place.
-
WEATHERED ROCK
This layer is made up of slightly unbroken rock and only a little bit of organic material is found here. Plant roots are not found in this layer.
-
TOPSOIL
A Horizon - The layer called topsoil; it is found below the O horizon and above the E horizon. This is where many animals most nutrients. This is where many animals live and has the most nutrients.
-
-
ORGANIC
O horizons: are soil layers with a high percentage of organic matter. Typically within a woodland area there are three distinct organic layers: one of leaves, pine needles and twigs ; underlain by a partially decomposed layer ;and then a very dark layer of well decomposed humus .
-
How is soil formed: Soil comes from broken pieces of rock and dead leaves,tree limbs, dead bugs.
Definition:The upper layer of earth in which plants grow, a black or dark brown material typically consisting of a mixture of organic remains, clay, and rock particles.
