Explanation / Answer
32) The origin of most organic plant matter is
Ans:- Decay of plant tissue because the organic matter is from the most living organisms and the plants .
33) When the soil profile formed
Ans:- A series of horizontal layers is said to be Horizon.all horizons together to form the soil profile.
The A horizon evolve into B horizon, then into C horizon. but the universal depositional sequence is O,A,B,R horizons
34) Permiability is defined as
Ans:- How poros the soil is or Number of pore spaces per unit volume is called its permiability.
35) Velocity of water flow is defined as
Ans:- Flow rate per Time units are meters/scond.
