Question

how does the parent rock affect the soil character

Answer 1

Answer:

Soil comes from parent rock. Due to weathering the action of plant roots etc the parent rock is broken up and over many years gets incorporated into the soil. So the composition of the parent rock will affect the soil that develops over it. The soil could be lacking in certain minerals due to the parent rock. The soil could be acidic or basic due to the parent rock.

But there is more to soil composition than just the parent rock.
