What are the three ways that a sedimentary rock can be changed and what is the result of each change?

Explanation:

Sedimentary rocks are rocks that are formed near the Earth’s surface. It js formed through a sucessive geological processes this include erosion, weathering, dissolution, precipitation, and lithification.

Physical weathering: Sedimentary rocks are layered rocks with many fractures from contracting during cooling. These cracks are opened up as the rock is brought to the surface and it allows water to get in. On freezing the water expands causing the cracks to widen and grow.

chemical weathering. Rain water can be slightly acidic and at times acid rain. This Acid dissolves many minerals particularly in crustal rocks, acid attacks carbonate found in sedimentary rock and feldspar, a principal ingredient of granite dissolving them.

Biological weathering:

Living things also lead to the breakdown of rock into fragments. Roots and burrowing animals physically disrupt rocks leading to the formation of soil.

The results of all the weathering processes is q heap of loose rock fragments and dissolved ions such as salt, bicarbonate, potassium.

The clastics blown away are carried by glaciers from the source region to a catchment area this is called sedimentary basin

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
