soil chapter 8

You can tell that the blank is the most fully evolved soil layer because it has more humus and smaller rock fragments than other layers.

A horizon

The writing is the layered blank the a horizon

Below

What factors help determine the type of soil - the thickness of layers and their composition.

Climate, slope,type of rock

Soil horizons blank more slowly in area that has little rainfall because chemical weathering occurs slowly and a dry climate

Evolve

What is the name of the process by which water carries materials of upper horizons down to lower levels

Leaching

Blank is a mixture of sediment of whether rock and organic matter

a horizon

DC horizon is the blank layer in the soil profile contains partly weathered rock and no hummus

bottom

where in the soil profile is solid rock being weathered

c horizon

The thickness of soil layers and their blank depends on climate, slope of land and the rock in an area and how long the soil has been evolving
