Answer 1

The correct option is D 1,2,3,4 &5

Soil formation is affected by all of the given factors. The rate of weathering is determined by climatic conditions of a given place. Depending upon the relief or slope, the amount of weathered particles deposited changes.

The slopes along a mountain will have thinner deposits as erosion is more on slopes, while foothills or plains will have thicker deposits.

Plants and small organisms grow, mature, die, and become part of this soil, adding to the humus content of the soil.
