Answer:
Step-by-step explanation:
The amount of space between rock and soil that can hold water is known as porosity. Porosity is a measure of the void spaces in a material, typically expressed as a percentage of the total volume of the material. In other words, it's the ratio of the volume of pore space in a rock or soil to the total volume of the rock or soil.
The porosity of rock and soil can vary widely, depending on the type of rock or soil and the conditions under which it formed. For example, some types of rock, such as sandstone, have high porosity (around 30-40%) because they are composed mostly of grains of sand that are held together by a small amount of cement. Other types of rock, such as granite, have very low porosity (around 1-2%) because they are composed mostly of tightly packed mineral crystals.
Soil, on the other hand, can have a wide range of porosity depending on the soil type. Sandy soils tend to have higher porosity than clay soils, but even within a soil type, porosity can vary greatly depending on the soil structure, organic matter content, and other factors.
In general, the porosity of rock and soil can range from less than 1% to over 40%. In order to hold water, the porosity should be greater than zero.
