I got this by Googling "three layers of soil".
There are three main horizons (called A, B, and C) which are present in all soil.
Organic - The organic layer (also called the humus layer) is a thick layer of plant remains such as leaves and twigs.
Topsoil - Topsoil is considered the "A" horizon. ...
Subsoil - Subsoil is considered the "B" horizon.
For more information, Google the same topic and read carefully.
it’s telling me to identify each layer and describe the three soil horizons and explain the formation and composition of each. can someone give me some websites to help? or some summaries of said websites?

IM ASKING HOW THEY ARE FORMED NOT WHAT GOES INTO THEM!!!
THIS SOOOOO DOES NOT HELP!!!!!!
There are six horizons. 1. O Horizon - The top, organic layer of soil, 2. A Horizon - The layer called topsoil, 3. E Horizon - This layer is beneath the A Horizon and above the B Horizon. It is made up mostly of sand. 4. B Horizon - Also called the subsoil - this layer is beneath the E Horizon and above the C Horizon. 5. C Horizon - it's called regolith: the layer beneath the B Horizon and above the R Horizon. 6. R Horizon - this is last and the unweathered rock layer that is beneath all the other layers.
