Answer. The rock from which soil is derived is called parent rock.
Where is the parent rock?
The term is also used in the context of metamorphic rocks where again the parent rock refers to the original rock before metamorphism takes place. Parent rocks can be sedimentary igneous or metamorphic. In these cases parent rock may be referred to as the protolith. Parent rock is the main source of soil.

What is the parent rock of marble?
The presence of the foliated rock likely slate suggests that before this rock metamorphosed it was composed of limestone (the parent rock of marble) layered with small-grained sedimentary rocks like siltstone or shale.
What is the meaning of parent material?
Definition of parent material
: the disintegrated rock material usually unconsolidated and unchanged or only slightly changed that underlies and generally gives rise to the true soil by the natural process of soil development.
What is parent material class 10?
Parent Material:- is deposited by streams or is derived from in-situ weathering. At this point soil has many properties such as mineral composition color particle size and chemical elements. Black soil for example derives its colour from lava rock. 2.
What does the term Protolith mean?

Which horizon is parent rock and why?
Bedrock or Horizon C
Bedrock is also known as parent rock and lies just below the subsoil. It contains no organic matter and made up of stones and rocks so it is very hard. This layer represents a transition zone between the earth’s bedrock and horizon A and B.
In what two ways can the parent rock affect the metamorphic process?
The main factors that control metamorphic processes are:
The mineral composition of the parent rock. The temperature at which metamorphism takes place. The amount and type (direction) of pressure during metamorphism. The amount and type of fluid (mostly water) that is present during metamorphism.
What is meant by the statement every metamorphic rock has a parent rock?
8.1 What is meant by the statement “Every metamorphic rock has a parent rock”? metamorphic rocks are produced from preexisting igneous sedimentary or other metamorphic rocks. So every rock has a rock from which it was formed (parent rock).

What is Land Class 8?
What is classing weathering 7?
Answer: Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down a process called erosion transports the bits of rock and minerals away. Water acids salt plants animals and changes in temperature are all agents of weathering and erosion.
What is the importance of parent rock class 8?
The parent rock determines the colour texture the chemical properties permeability and the mineral content of the soil. At the same time climatic conditions like temperature and rainfall determine the rate of rock weathering and existence of humus in the soil.
What kinds of materials can be a parent rock?
