Question

Percolation rate is defined as:

• A. Rate at which water is absorbed by subsoil
• B. Rate at which air is absorbed by soil
• C. Rate at which water trickles down the soil
• D. Rate at which air trickles into soil

Answer 1

The correct option is C Rate at which water trickles down the soil

Percolation is the movement of water through soil, and the percolation rate is the speed at which that movement occurs. Percolation rate is calculated using the following formula:
Percolation rate = $\frac{\text{Amount of water (mL)}}{\text{percolation time (mins)}}$
