It's the layer of organic matter in soil. The organic matter largely is built up by the death and decay of organisms that live in soil. Some such organisms include bacteria, beetles, earthworms, and moles.
topsoil.
The layer that contains the most humus and smaller rocks is the topsoil layer. Topsoil is the uppermost layer of soil that is rich in organic matter, such as humus, and contains smaller rock particles that have undergone weathering. It is the most fertile layer of soil and is crucial for plant growth.
The top layer of soil, called the O horizon or organic layer, contains humus. Humus is a dark, organic material that forms as plant and animal matter decomposes. It is rich in nutrients and helps improve soil structure and fertility.
The layer of Earth with the greatest amount of decayed material is the topmost layer, known as the soil layer or the humus layer. This layer contains organic matter formed from the decomposition of plants and animals, contributing to soil fertility.
The C and R horizon
All soil contains some humus. If it doesn't it is not soil.
It is false that the loose material on Earth's surface that contains weathered rock particles and humus is bedrock. The loose weathered material on Earth's surface in which plates can grow is soil.
The stratosphere layer of the earth's atmosphere contains the ozone layer. This ozone layer protects against the harmful ultraviolet radiations of the earth.
An atmospheric layer that contains layer is stratosphere. It contains ozone layer.
The layer that contains gases in distinct layer is troposphere. It is closest to earth.
Stratosphere contains layer of ozone. It is called as ozone layer.
Stratosphere is the layer of atmosphere. It contains the ozone layer. Ozone is the blanket on earth.
