What are the three main layer of the soil?

Answer 1

Infact there are four layers and not three.They are:

1.Horizon A or Top soil (with humus)

2.Horizon B or Sub soil(sand ,silt and clay)

3.Horizon C or Weathered rock

4.Horizon D or Bedrock.

thats all!!
Soil has three main horizons (A, B, and C),

layers are as folllows

O Horizon

P Horizon

A Horizon

E Horizon

B Horizon

C Horizon

D Horizon

R Horizon (bedrock)

Answer 2

I learned in Science class that the three main layers of soil are:has_a_large_amount_of_decay_mostly_made_out_of_humus._Many_organisms">has_a_large_amount_of_decay_mostly_made_out_of_humus._Many_organisms">1. topsoil- has a large amount of decay mostly made out of humus.

Answer 3

With the associated link and my telling you that the three "layers" your instructor is probably seeking are the A, B and C horizons, you can describe the "three" layers of a soil profile.

(BTW, it is not unusual to have more than three horizons.)

Answer 4

Topsoil, then subsoil, then bedrock. Don't blame me, I'm just a person.

Answer 5

1.Topsoil

2.Subsoil

3.Bedrock

Answer 6

The three layers of soil are surface, subsoil, and substrata. The subsoil is about 2 inches down and the substrata below 3 inches.

Answer 7

The 3 main ones are

Crust, like the part we live on.

cant remember the second. its pretty much rock thought

core, the lava

Answer 8

top soil

subsoil

bedrock
