Horizon is a side profile of the layers of
soil
Soil is usually divided into 3 main layers,
but will also include the layers above and
below for a total of 5 layers.

O Horizon: Litter
 
Not really a layer of soil
It’s on top of the first layer of soil
Contains grass, plants, and animals
A Horizon: Topsoil
 
1
st
 layer of soil
Darkest layer of soil (dark brown or black)
Contains humus, plant roots, small animals,
water, and nutrients for plant growth
The darker the soil, the more nutrients it
contains
B Horizon: Subsoil
 
2
nd
 layer of soil
Lighter in color (reddish brown)
Fewer nutrients and water
Limited plant growth
C Horizon: Parent Material
 
3
rd
 layer of soil
Lightest in color (gray)
No nutrients, animals, or plant growth
Contains weathered rock and sediment
R Horizon: Bedrock
 
Below the last layer of soil
Solid Rock
Has not been weathered or broken down
yet
No soil in this layer
