Rocks are broken down into smaller pieces by physical weathering processes like wind and water erosion. Over time, organic matter from plants and animals accumulates on the rock fragments, breaking them down further. The combination of rock fragments and organic matter eventually forms topsoil through the process of weathering and decomposition.

Does subsoil contain more organic matter than topsoil or parent rock?
yes
What is stratum below topsoil?
Below the topsoil is the subsoil layer. This layer typically contains less organic matter and nutrients compared to topsoil. It often consists of weathered rock, clay, and minerals that are broken down from the topsoil layer above.
Three layers of the soil with picture?
The three layers of soil are topsoil, subsoil, and bedrock. The topsoil is the uppermost layer containing organic matter and nutrients for plant growth. Subsoil lies beneath the topsoil and consists of partially weathered rock and minerals. Bedrock is the bottommost layer, made up of solid rock that extends deep into the ground.
What layer or layers of soil includes rock particles mixed with dark products of decay?
The layer that includes rock particles mixed with dark products of decay is the topsoil layer. Topsoil is the uppermost layer of soil that is rich in organic matter and supports plant growth. It is a combination of mineral particles, organic matter, and nutrients that are essential for plant development.
What is the lowest level of rock which is usually the original source of topsoil?
The lowest level of rock that is usually the original source of topsoil is bedrock. Bedrock is the solid rock layer located beneath the soil layers and is the parent material from which soil is formed through weathering and erosion processes.
Can sedimentary rock be changed into igneous rock?
If it is forced back into the molten layers of the Earth, then yes, it will become igneous rock.
Rock horizons in order?
A - Topsoil B - Subsoil C - Weathered Rock Bedrock
Can an igneous rock be changed into a metamorphic rock?
Yes. Among some of the more common changes, granite can become gneiss and basalt can become greenstone.
Is it possible for a sedimentary rock to be changed to become a new sedimentary rock?
Yes, sedimentary rocks can undergo processes such as compaction, cementation, and recrystallization to become a new sedimentary rock. These processes can alter the original sedimentary rock's texture, composition, and appearance without undergoing metamorphism.
Does subsoil contain more organic matter than topsoil or parent rock?
yes
What type of rocks can be changed into metamorphic rocks?
Any type of rock can become metamorphic.
Did topsoil always been present upon planet Earth?
No, topsoil takes thousands of years to accumulate. When Earth was very young, it was mostly rocks and lava. After the atmosphere settled in, and erosion of rock began, and organisms showed up, topsoil began to accumulate over the rock.
What is stratum below topsoil?
Below the topsoil is the subsoil layer. This layer typically contains less organic matter and nutrients compared to topsoil. It often consists of weathered rock, clay, and minerals that are broken down from the topsoil layer above.
What rocks change into metamorphic rocks?
Any type of rock can become metamorphic.
Three layers of the soil with picture?
The three layers of soil are topsoil, subsoil, and bedrock. The topsoil is the uppermost layer containing organic matter and nutrients for plant growth. Subsoil lies beneath the topsoil and consists of partially weathered rock and minerals. Bedrock is the bottommost layer, made up of solid rock that extends deep into the ground.
Is there a sentence with the word rock cycle?
Igneous rock can weather and become sedimentary rock . Metamorphic rock can be melted in a volcano and become igneous rock. Igneous rock and sedimentary rock can be heated and pressurized to form metamorphic rock.
Does topsoil become richer as dead plants decay?
yes
