which increases the rate of soil formation?\no mixed layers\no more precipitation\no cooler temperatures\no very hard parent material

which increases the rate of soil formation?\no mixed layers\no more precipitation\no cooler temperatures\no very hard parent material

Answer

Brief Explanations:

Precipitation aids in weathering of parent - material and leaching, which speeds up soil formation. Mixed layers don't directly increase the rate. Cooler temperatures slow down chemical and biological processes in soil formation. Hard parent material is more difficult to break down, thus slowing soil formation.

Answer:

more precipitation
