Answer: The answer is B
Explanation: Because it does not describe changes due to selective breeding.
The bare soil surface type affects the amount of runoff because it has
no other stopping mechanism that prevents runoff to happen. Just like in the
use of pesticide, it is
harmful to human agriculture because it contains an antifreezing chemical
(present in transportation vehicles). When the chemical seeps into the soil, it
will create a runoff and can seep into the groundwater causing pollution.

D. Take many thousands of years to form
Explanation:
James Hutton discovered thin layers of sediments on his flooded farm and he concluded that strata was part of the earth surface in the past and thus takes many thousands of years to form.
This led to the principle of uniformitarianism which states that the geologic processes now are the same with the ones in the past.
