What are the two types of weathering?
Mechanical Weathering
Chemical Weathering
Temperature Weathering
Glacier Erosion
What are the agents of weathering, erosion and deposition?
Air
Water
Ice
Gravity
What are the examples of mechanical/physical weathering?
Biological (plant roots, animal burrows.)
Abrasion (Rocks rubbing against each other.)
Freezing/Thawing
Exfoliation (Peeling)
Thermal Expansion or temperature changes
What are 3 examples of chemical weathering?
Hydrolysis
Oxidation
Dissolution
Frost Wedging
What is the difference between mechanical and chemical weathering?
In Mechanical weathering, the composition of the rock does not change and then later changes. And in Chemical Weathering, it does the same thing.
In Mechanical weathering the composition of the rock changes. And in Chemical weathering, the composition of the rock does not change.
In Mechanical weathering the composition of the rock does not change. And in Chemical weathering, the composition of the rock does change.
In Mechanical weathering the composition of the rock does not change. And in Chemical weathering, the composition of the rock does not change either.
What is oxidation?
Oxidation is a type of Chemical weathering in which the process of dissolving or breaking apart.
Oxidation is a type of Chemical weathering in which oxygen reacts with the metals in rocks to weaken the rock
Oxidation is a type of Chemical weathering in which water is used to break down the bonds of a particular substance.
Oxidation is a type of Chemical weathering which is the breaking down of rocks. Chemical weathering is caused by animals and plants.
What is a glacier?
Glaciers are coastal lands due to the net removal of sediments or bedrock from the shoreline.
A glacier is an enormous sheet of snow-covered ice that slowly accumulates on a mountain.
How does strip mining affect erosion?
Strip mining increases erosion because sections of the Earth are moved away and plants no longer prevent the erosion of soil.
Strip mining decreases erosion because sections of the Earth are not moved away and plants prevent the erosion the soil faster.
Strip mining is not a thing anymore. Strip mining only existed back in the 1770's. It is also now illegal.
None of these answers are correct. Therefore, this is the only, most correct answer for question 8.
What is deposition?
The process in which small, solid particles of material from rocks or organisms which are moved by water or wind.
The process when physical and chemical events which causes soil and rock on the Earth's surface to loosen and move to a new location.
The process by which sediment settles out of the water or wind that is carrying it, and is deposited in a new location.
Deposition is the breakdown or loosening of surface minerals of rocks after they are exposed to weathering agents such as water , oxygen (air), organic and inorganic chemicals and temperature.
What is the composition of soil?
(What is soil made of?)
Air
Water
Sediments (clay, silt, sand)
Humus (organic material)
Ice
What is humus?
Humus is a colorless, transparent, odorless, tasteless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.
Humus is a naturally occurring material that is broken down by processes of weathering and erosion and is subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles.
Humus is a stiff, sticky fine-grained earth, typically yellow, red, or bluish-gray in color and often forming an impermeable layer in the soil.
Humus is the organic component of soil, formed by the decomposition of leaves and other plant material by soil microorganisms.
What is residual soil?
Residual soil is soil that remains above the bedrock from which it was formed.
Residual soil is soil that has been moved away from the bedrock from which it was formed.
Residual soil is soil that remains below the bedrock from which it was formed.
Residual soil is fine sand, clay, or material carried by running water and deposited as sediment.
What is transported soil?
Transported soil is soil that remains above the bedrock from which it was formed.
Transported soil is soil that has been moved away from the bedrock from which it was formed.
Transported soil is soil that remains below the bedrock from which it was formed.
Transported soil is fine sand, clay, or material carried by running water and deposited as sediment.
What are the ways to conserve soil?
Windbreak
Terracing
Contour Plowing
Crop Rotation
Cover Crops
