Porosity is a measure of void space in a soil sample. Larger soil particles have larger void spaces. Smaller soil particles have smaller pore spaces, but a greater number of them, which leads to higher surface tension and higher % porosity. With this is mind, which statement is true:

Sandy soil has a higher porosity than clay soil

Sandy soil has a higher porosity than silty soil

Clay soil has a higher porosity than sandy soil

Porosity is directly proportional to soil particle size

100 %
