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: A. Sandy soil has a higher porosity than clay soil
B. Sandy soil has a higher porosity than silty soil
C. Clay soil has a higher porosity than sandy soil
D. Porosity is directly proportional to soil particle size
