2.Silt is made up of rock and mineral particles that are larger than clay but smaller than sand. Individual silt particles are so small that they are difficult to see.
3.clayparticles are the smallest
ACTIVITY2
soil four layers
1) O horizon;
2) A horizon;
3) B horizon, or subsoil;
4) C horizon, or soil base ;
different characteristics
1)The O horizon has freshly decomposing organic matter—humus—at its surface, with decomposed vegetation at its base.
2)The A horizon consists of a mixture of organic material with inorganic products of weathering, and it is therefore the beginning of true mineral soil.
3)The B horizon is an accumulation of mostly fine material that has moved downward, resulting in a dense layer in the soil.
4)The C horizon, or soil base, includes the parent material, plus the organic and inorganic material that is broken down to form soil. The parent material may be either created in its natural place, or transported from elsewhere to its present location. Beneath the C horizon lies bedrock.
