1. Weathering
2. Physical weathering
3. Weathered rock particles and water
4. List and explain the five main factors of soil formation
a. Parent material
-
Parent material is the material from which soil develops which could be rock that has
over time decomposed in a place or material which was deposited there. The
composition of the parent material determines the properties of soil which develops
from it. Soil which develops from parent material which is coarse and resistant to
weathering is likely to be coarse grained. Soil which develops from parent material
which is unstable and weathers readily is likely to be fine-grained.
b. Climate
-
Climate influences the energy that affects soil formation affecting the chemical and
physical composition of soil. In addition, climate also dictates the vegetation cover
which in turn affects soil development.
c. Topography
-
Topography determines soil formation since it affects water runoff and topographic
orientation has an effect on vegetation which also affects soil formation. For the
horizontal process to proceed, the parent material ought to be undisturbed but in cases
of soil erosion the pa...
