To form soil, the two processes which must occur are erosion and weathering, so the correct answer here is B. Soil formation is a continuous process, but also one which takes a long time. It can sometimes more than five hundred years for 1cm of soil to form.

I took the test and the answer is A. 'weathering breaks rocks into minerals and plants die and decay'
