All soils come from a parent rock. The parent rock is broken down due to weathering, will eventually after many years will become a fine crumbly soil. Different parent rocks produce different soils.

Soil is the uppermost layer on the Earth's surface that consists of weathered rock, organic matter, air, and water, supporting plant growth. Parent rock, on the other hand, is the underlying bedrock from which the soil is derived through weathering and erosion processes. Soil is the product of weathering and decomposition of parent rock over time.

Which best explains the relationship between parent rock and soil composition?
Soil composition is directly influenced by the parent rock from which it is formed. The mineral content and structure of the parent rock determine the composition of the soil through weathering and erosion processes. Therefore, the parent rock plays a crucial role in shaping the characteristics of the soil that will develop from it.
How does parent rock affect soil?
Parent rock influences soil formation by determining the mineral composition and physical characteristics of the soil. Weathering of the parent rock releases minerals that become part of the soil composition, while the size and structure of the parent rock can impact soil texture and drainage. Different parent rocks result in soils with varying nutrient levels and pH levels.
Which soil horizon contains parent rock?
The C horizon typically contains parent rock material, which is the unweathered rock from which the soil has developed.
Is the parent rock the largest component of soil?
No, the parent rock is not the largest component of soil. Soil is composed of a mixture of mineral particles, organic matter, water, and air. The parent rock contributes to the mineral content of the soil through its weathering and breakdown processes.
When is the parent rock the same as bedrock?
When the soil above it formed from the bedrock below.

What is the soil that remains above its parent rock?
residual soil

When the soil above it formed from the bedrock below.
Why is bed rock called the parent of soil?
Bedrock is considered the parent material of soil because it is the underlying, unweathered rock that is slowly broken down over time by physical, chemical, and biological processes to form soil. Soil formation starts with the weathering of bedrock, making it the source material for soil development.
What is the role of the parent rock in the creation of a soil?
The parent rock influences the mineral composition and structure of the soil through weathering processes. Different types of parent rock lead to the formation of different soil types, such as sand, silt, or clay. It also determines the fertility and nutrient content of the soil.
Soil that remains above its parent rock?
Residual soil is soil that remains above its parent rock, formed by the weathering and erosion of the rock over time. This soil is typically rich in minerals and nutrients that have been released from the parent material through weathering processes. Residual soil often retains similarities in composition and structure to the underlying rock.
How does rock affect soil?
Soil comes from parent rock. Due to weathering the action of plant roots etc the parent rock is broken up and over many years gets incorporated into the soil. So the composition of the parent rock will affect the soil that develops over it. The soil could be lacking in certain minerals due to the parent rock. The soil could be acidic or basic due to the parent rock. But there is more to soil composition than just the parent rock.
What best explains the relationship between parent rock and soil composition?
The parent rock largely determines the mineral content of the soil through weathering processes. Rocks high in minerals like quartz will yield sandy soils, while those with more clay minerals will form clayey soils. The composition of the parent rock influences the fertility and nutrient content of the resulting soil.
When soil remains on top of its parent rock it called?
When soil remains on top of its parent rock, it is called residual soil. This type of soil forms directly from the weathering of the underlying rock, without being transported to a new location.
