What layer of soil contains the most decayed material?

The top layer of soil, known as the organic horizon or O horizon, contains the most decayed organic material. This layer consists of partially decomposed plant and animal matter, such as leaves, twigs, and dead organisms.


What is the layer of soil with little or no organic matter?

The layer of soil with little or no organic matter is called the mineral soil horizon. This layer is typically composed mainly of inorganic materials such as sand, silt, and clay, with very little decayed plant or animal material.


What layer of the atmosphere has the greatest amount of water vapor?

The layer of the atmosphere with the greatest amount of water vapor is the troposphere. This is the lowest layer of the atmosphere and is where most weather events occur. Water vapor plays a crucial role in cloud formation, precipitation, and other atmospheric processes in the troposphere.


What Horizon has the highest amount of organic material?

The uppermost layer of the soil, known as the O Horizon, contains the highest amount of organic material. This layer consists of decomposing plant and animal matter, as well as living organisms like fungi and insects that aid in the decomposition process.


What is the parent material layer?

The parent material layer is the unconsolidated material from which the soil develops. It is the source material that undergoes weathering processes to form soil over time. The characteristics of the parent material influence the properties of the soil that develops from it.
