Water plays an important role in the chemical weathering of rock. In 3-5 sentences, identify and explain two agents of chemical weathering to support that statement.

agents of chemical weathering are water, carbon dioxide ,

Explanation:

chemical weathering is the gradual disintegration of rocks as a result of chemical reactions. when rain falls on the rock surface, the water combines with the carbon dioxide to produce a weak carbonic acid.   water being the main cause of chemical weathering, the small amount of carbon dioxide that in the atmosphere dissolves in rain water. the water falls on the rock and the rain water moves on the soil surface thereby picking up additional carbon dioxide from debris. in this process rocks are broken down into smaller particles.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !
