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 last layer of soil to form a horizon?

The last layer of soil to form a horizon is called Horizon C. This layer is often referred to as the parent material, as it is made up of weathered rock fragments that have not yet fully decomposed into soil. Horizon C is the layer closest to the bedrock and has the least amount of organic matter.

What factors in an atmosphere seem to have the greatest effect on the amount of radiation received from the sun?

The ozone layer has the greatest effect on the amount of ultraviolet radiation received at the earth's surface from the Sun. Cloud formation and atmospheric thickness, in combination with solar angle, have the greatest effect on the amount of visible and infrared radiation received at the earth's surface from the sun


What is the dark organic rich material formed as a top layer in soil from the decayed remains of plants and animals?

The dark organic rich material formed as a top layer in soil from the decayed remains of plants and animals is called humus. It is a crucial component of healthy soil, enhancing its fertility, structure, and water-retention capacity. Humus results from the decomposition of organic matter, contributing essential nutrients to support plant growth and promoting microbial activity in the soil ecosystem.


What is the layer of partly decayed plant and animal matter in the forest floor called?
