The rate at which water flows through the soil is called soil percolation or ______.
Groundwater
Permeability
Soil Pores
Porosity
The layer(s) of soil in which most of the humus and soil organisms are contained:
1- leaf litter, horizon O
2- topsoil, horizon A
3- subsoil, horizons B and C
1 only
2 only
1 and 2 only
2 and 3 only
1, 2, and 3
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
