Answer:
Physical weathering enhances the rate of chemical weathering .
Explanation:
Physical weathering is the breaking down of rocks by various processes like freezing and thawing without altering the rocks chemical composition.
While, chemical weathering involves the disintegration and dissolution of rocks by the chemical processes like oxidation , carbonation and solution processes etc.
Generally a fractured rock can easily be weathered by chemical agents rather than a normal fractured rock.
So ,
when a rock is already subjected to physical weathering, the rock will develop cracks on it and when the chemical agents comes in contact with that rock, the chemical solution will penetrate into those cracks and will dissolve the rocks at a rapid rate.
I know it might be too late, but I believe the answer is B) US research and design with mostly Asian production.
Explanation:
<u>Sun is composed of plasma and hot gases . Due to the dynamo process , the magnetic field of the sun is generated .</u>
The energy of sun is originated from the thermonuclear fusion reaction , that occurs on the surface of the sun .
Since , sun has a very strong gravity , hence the atoms of hydrogen fuse to form helium .
The reaction , i.e. , nuclear fusion , when the hydrogen atom converts to the atom of helium , the by product of this reaction is huge amount of energy , which is responsible for the energy source on the sun .
