Question

Gretta has a sample of soil. She wants to know what its porosity is. How could she test the soil's porosity? A. Measure the time it takes water to make it through the soil when placed in a funnel. B. Measure the mass of the soil and then measure its volume. C. Measure the amount of water that evaporates from the soil in one hour. D. Measure the soil's volume and then the volume of water that the soil can absorb.

Answer 1

Answer:

Option- D. "Measure the soil's volume and then the volume of water that the soil can absorb" is the right answer.

Explanation:

Porosity of the soil is defined as the amount of empty spaces or pores that are present between soil particles due to movement of insects, earthworms and roots of the plants. Porosity is very necessary for the growth of the plant and other fauna that is present in the soil because it provides oxygen to them.

We can find the porosity by calculating the quantity of water that the soil needs to fill the empty spaces.
