The B Horizon is known as

A crumbly, dark brown soil that is a mixture of humus, clay, and other materials

a dark-colored substance that forms as plant and animal remains decay

Soil that is made up of about equal parts of clay, sand, and silt

a layer of soil that differs in color and texture from the layers above or below it

the organisms that break down the remains of other dead organisms

Consists of clay and other materials washed down from the A horizon, but little humus

any material produced originally by living organisms (plant or animal) that is returned to the soil and goes through the decomposition process

the steepness, landscape position and surface shape of a section of land

a gradual process of movement and transport of the upper layer of soil (topsoil) by different agents – particularly water, wind, and mass movement – causing its deterioration 

the process of erosion produced by the suspended particles that impact on solid objects. Windblown grains of sand, carried along at high speed, are a very effective tool that can sandblast away rocks by abrasion

the accumulation of sediments by either physical or chemical sedimentation

weathering processes that cause exposed rock to undergo chemical decomposition, changing the chemical and mineralogical composition of the rock ~ Oxygen and acids are agents in chemical weathering

The process of weathering by which frost action, salt-crystal growth, absorption of water, and other physical processes break down a rock to fragments, involving no chemical change

occurs when frozen precipitation falls over an area and seeps into small cracks in rocks and other materials. As the ice and snow begin to melt, it liquifies and pools into these crevices, and then refreezes at night
