The terms "horizon a" and "horizon b" typically refer to layers in a soil profile or stratigraphic sequence, with "horizon a" often representing the uppermost layer, such as topsoil, while "horizon b" is usually a deeper layer beneath it. Therefore, horizon a is generally considered to be on top of horizon b. However, the specific context may vary, so it's essential to clarify the definitions being used in each case.

List soil horizons in the correct order from top to bottom?

The correct order of soil horizons from top to bottom is O, A, E, B, C. The O horizon is organic matter on the surface, the A horizon is topsoil with organic material mixed with mineral particles, the E horizon is a zone of leaching, the B horizon is subsoil with accumulated minerals, and the C horizon is weathered parent material.


How are soil horizons ordered from the top of the profile to the bottom?

Soil horizons are ordered from top to bottom as O, A, E, B, C, and R horizons. The O horizon is the top organic layer, followed by the A horizon of topsoil. The E horizon is a zone of leaching, the B horizon contains minerals leached from above, the C horizon consists of partially weathered parent material, and the R horizon is unaltered bedrock.


What is the correct order of the different soil horizons?

The correct order of soil horizons, from top to bottom, is O horizon, A horizon, E horizon, B horizon, C horizon, and R horizon. It is important to note that not all soils have all these horizons, as they can vary depending on the specific conditions of the soil.


What is horizon b's name?

Horizon B's name is Horizon Brave.


What are the three major soil horizons?

The three major soil horizons are A horizon (topsoil), B horizon (subsoil), and C horizon (parent material). The A horizon is the top layer that contains organic matter and nutrients, the B horizon is the layer below that is richer in minerals, and the C horizon is the weathered rock or sediment from which the soil forms.


How do A horizon and B horizon form?

A & B Horizon forms wherever bedrock is exposed.


How do horizon a and horizon b form?

A & B Horizon forms wherever bedrock is exposed.


Which soil horizon develops as rainwater washed clay and minerals from the A horizon to the B horizon?

The B horizon develops as rainwater washes clay and minerals from the A horizon to the B horizon below it. This process is called leaching. The B horizon typically contains more clay and accumulated minerals than the A horizon.


In a cross section of soil the b horizon consists of?

horizon a= topsoil horizon b= subsoil i think horizon c im not sure of and then bedrock


How do the a horizon and b horizon form?

There are many things that horizon A and horizon B could form. These things include slopes and lines for example.


How do the A horizon and the B horizon form?

There are many things that horizon A and horizon B could form. These things include slopes and lines for example.


What are the individual layers of soil?

The individual layers of soil, from top to bottom, are the O horizon (organic matter), A horizon (topsoil), B horizon (subsoil), C horizon (weathered parent material), and bedrock. Each layer has distinct characteristics and composition that influence soil fertility and productivity.
