Which layer of soil contains the most fertile soil?
The topsoil layer contains the most fertile soil. It is the upper layer of soil that is rich in organic matter, nutrients, and microorganisms, making it ideal for plant growth.
What is the layer of soil?
The layer of soil is called the topsoil, which is the uppermost layer of soil that contains most of the organic matter and nutrients that plants need to grow. It is typically the darkest and richest layer of soil, where most plant roots are found.
Which change would most likely cause soil layer to increase in thickness?
Increased deposition of sediment over time would most likely cause a soil layer to increase in thickness. This can happen through processes like erosion, weathering, and the accumulation of organic matter, which contribute to the gradual build-up of soil over time.
What is the layer of soil that contains the most humus and smaller rock?
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.
Which layer of soil is the oldest?
Umm... let's see. The top layer is top-soil. The middle layer is sub-soil. The bottom layer is parent rock.... I think you've got the answer...... ;-) you're welcome!
Which of the layers is most likely to contain pests?
the surface layer and top soil
What is the name for a horizontal layer of soil?
There are four layers and the four layers are top layer called the organic layer, Upper soil layer, middle soil layer, and the last one is lowest layer.
What layer of soil is most likely to contain living organisms?
The top layer, known as the topsoil, is most likely to contain living organisms such as bacteria, fungi, worms, and other microorganisms due to its high levels of organic matter and nutrients. These organisms play a vital role in soil health and nutrient cycling.
Which 2 layers of the soil are least likely to contain humus?
The layer of soil that has little or no humus in it is the subsoil. The top layer of the soil has the most humus in it because the dead leaves fall from the plant and go back into the soil. Water and sun also help give the plant humus.

Why is it harmful to waste the top layer of soil?
The top layer of soil is the most fertile layer. It is the best for growing crops.
What is the soil layer with the most parent material?
Top soil

Which layer of soil is least likely to be penetrated by plant roots?
The parent rock layer is least likely to be penetrated by plant roots due to its hard and compact nature. Roots typically grow in the upper layers of soil where there is more organic matter and nutrients available for plant growth.
