Compare the pros and cons of using different renewable energy resources.

What part does infiltration play in the water cycle?

Surface runoff of precipitation occurs when

(1) porosity is exceeded by permeability

(2) the infiltration rate is greater than the precipitation rate

(3) the precipitation rate is greater than the infiltration rate

(4) the evaporation rate is increased.

As the temperature of soil decreases from $10^{\circ} \mathrm{C}$ to $-5^{+} \mathrm{C}$, what will most likely happen to the infiltration rate of water through the soil.
