Chemical Weathering
The breakdown of rocks and geological structures due to a change in chemical composition.
What is Chemical Weathering?
Is the physical breakdown of rocks without any changes to the chemical composition.
What is Physical/Mechanical Weathering?
Is the result of the actions of organisms.
What is biological weathering?
Often two or more different weathering methods work together to break down geologic structures.
What is joint process?
The process of breaking down material
What is weathering?
When society uses fossil fuels like gasoline and coal, it releases chemicals into the atmosphere, resulting in this.
What is acid rain?
These events occur as rock material grinds along the surface of other rock material. It is much like a slide at a park.
What are slides?
This weathers geologic structures as they dig for food or to create burrows for their homes
This actually contributes to speeding up chemical weathering
What is physical weathering?
The part of the erosion process where rock material is removed
What is erosion?
Occurs when sufficient water from the atmosphere precipitates on rocks high in calcite (limestone, marble). Eventually breaking down rocks.
What is acid reaction?
Occurs when soils are able to rotate, the base sliding forward and the top of the slope moving vertically
What are slumps?
This often digs themselves deep into the ground, break up rocks and other features.
What are tree roots?
Frost thaw action breaks rock to expose more rock surface to oxidation and acid reaction (two answers)
What is chemical and physical weathering?
Occurs when sufficient water from the atmosphere precipitates on rocks high in calcite (limestone, marble).
What is oxidation?
This type of physical weathering occurs when water gets into space in rock and freezes
What is freeze-thaw action?
This is added to the soil from the decomposition of animals and plants.
What is organic material?
Plant roots intrudes into soil layer to loosen it enough for a physical weathering to take over (two answers)
What is physical and biological weathering?
The part of the erosion process where rock material is placed somewhere.
What is deposition?
Generally, _______ a mineral's value on Moh's Scale of Hardness the more resistant it is to breaking down.
What is the higher?
Occurs when a rock's internal pressure is not balanced by external pressure.
What is exfoliation?
One of the best known burrowing animals is this thing.
What is an earthworm?
Some plants release use chemicals as a means of survival which is released into the environment to increase acid reaction (two answers)
What is biological and chemical weathering?
Formed when wave deposits have erosion take place behind them
What are Barrier Islands?
