The speed and distance of movement, as well <br /> as the amount of soil and rock material, vary greatly. <br /> Large stones <br /> Rock fragments 3 inches (7.6 centimeters) or more across. Large stones <br /> adversely affect the specified use of the soil. <br /> Lava flow(map symbol) <br /> A solidified, commonly lobate body of rock formed through lateral, surface <br /> outpouring of molten lava from a vent or fissure. <br /> Leaching <br /> The removal of soluble material from soil or other material by percolating water. <br /> 52 <br />
