Is a factor that affects soil development.
a. time
c. type of rock
b. slope
d. all of the above

d. all of the above

Explanation:

A soil is a mixture of organic matter, gases, minerals, liquids and living organisms. It is formed by the process of weathering of parent rocks. The contents of the weathering are added up with the organic matter added up by the plants, animals and other living agents. The soil formation is a time consuming process with due course of time new ingredients are added up to the composition of soil. The slope may also affect the soil formation as this will prevent the retention of water inside the soil and may cause the separation of aggregated ingredients which are required to compose the soil.

On the basis of the above description, all of the above is the correct option for soil development.
