2. Climate: Temperature and rainfall influence the rate of weathering.
3. Relief: Altitude and slope determine the accumulation of soil at a place.
4. Flora, fauna and microorganism: These are the biotic factors which affect the rate of humus formation
5. Time: Time determines the thickness of soil profile.
