Why do you not find humus on slopes? lack of dense vegetation too much topsoil lack of rainwater abundance of nutrients?

lack of dense vegetation

Explanation:

Humus is the product resulting from the decomposed organic matter, from the digestive process of earthworms, forming a natural compost, adding to the soil the remains of animals and dead plants and also their by-products. This organic matter is a result of the fall of plant material in the soil, for this reason, areas with dense vegetation have soil rich in humus, however areas such as hillsides that do not have dense vegetation are poor in humus.

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes
