Question

Why does water move more slowly through clay than through humus?

Answer 1

The reason why water is able to move more slowly through the substance, clay than through the humus is because compared to the humus, the clay has a smaller pore space where the humus is much bigger compared of the clay, having the water move faster than the clay.

Answer 2

This question is incomplete. The completed question is below

why does water move more slowly through clay than humus?

a. clay has greater permeability

b. clay has very small pore space

c. clay prevents capillary attraction of water

d. clay reduces evaporation rates.

The correct option is b

Step-by-step explanation:

Clay soil contains highly compact particles (called clay) whose pore sizes are small because clay is a finely flat particle while humus soil is made up of finely divided particles. This finely divided particles are decomposed as a result of microbial action in soil, these microbes decompose both plants and animal substances leaving large pore sizes in the soil which allows for easy movement of water in them and also allows for further microbial activity.

The small pore sizes in clay is the reason for slow water movement in them.
