Soil develops as rocks are broken down by physical weathering (such as wind and water erosion) and chemical weathering (such as acid rain and biological activity). Over time, organic matter accumulates from plant material and microbes, leading to the formation of soil horizons with distinct layers based on their composition. This process can take hundreds to thousands of years to create fertile soil capable of supporting plant life.

How does soil evolve?
Soil evolves over time through processes like weathering of rock, organic matter accumulation, and microbial activity. Factors such as climate, topography, parent material, organisms, and time influence the development of different soil types and properties. These processes create layers of soil with distinct characteristics and support various ecosystems.
What does all soil begin as?
All soil begins as rock that is broken down by weathering and biological activity over time.
Is soil or rock formed first?
All soils owe their existence to rock. Rock came first.
What is the relation between soil and rock?
Soil is formed from the weathering and breakdown of rocks over time. Rocks are the parent material of soil, and the composition of soil is influenced by the type of rock that has weathered to form it. Rocks provide minerals and organic matter that contribute to the formation and fertility of 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.

Does hot lava become rock or soil?
It cools to form igneous rock, which over time may be eroded down to become a component of the soil. The larger contributor to rich soil around volcanoes is the ash which settles after an eruption.
What is a gradual change in the members of a community over time is called?
A gradual change in the members of a community over time is known as succession. This process involves a series of predictable changes in the species composition and structure of a community as it evolves towards a stable state. Succession can be primary (starting from bare rock or soil) or secondary (following a disturbance).

When soil first forms over bare rockwhat is it made of?
When soil forms over bare rock, it is made up of weathered rock particles, organic matter from decaying plants and animals, and a mix of minerals and nutrients. Over time, soil formation processes such as weathering, erosion, and biological activity continue to enrich and develop the soil profile.
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 does the following sentence mean soil were once rock?
soil was first rock,which then later turned to soil by a factor that they where broken down to soil by rain
Why is bed rock called the parent of soil?
Bed rock is called the parent of soil because soil formation begins when bed rock is broken down by weathering . Weathering breaks the parent rock into smaller and smaller peices later on the weathered rock is broke down into soil particles. :-)
Where is this soil profile is solid rock being weathered into soil?
In the C horizon
