When the chemical composition of a rock changes, it undergoes a process called metamorphism. This can happen due to high pressure, temperature, or the presence of chemically active fluids, causing minerals in the rock to recrystallize into new forms. The original rock's minerals may be altered or new minerals may form, resulting in a different appearance and texture.

Is grinding salt a chemical or physical change?
physical
Can you put Chemical weathering in a sentence?
Chemical weathering is the breakdown of rocks caused by chemical reactions, leading to the alteration of the rock's composition and structure over time.
Is the rock cycle a chemical change or physical change?
The rock cycle involves both physical and chemical changes. Physical changes involve processes like weathering and erosion that break down rocks physically. Chemical changes occur when minerals in the rocks react with water or gases to form new minerals.
Chemical change for rocks?
chemical weathering can change a rock by the water freezing inside the roclk and the crease of the rock breaking by the frozen water inside of it.
Explain the difference between chemical and physical weathering?
Chemical weathering involves the breakdown of rocks through chemical reactions, such as oxidation or dissolution. Physical weathering, on the other hand, occurs when rocks are broken down into smaller pieces through physical processes like freezing and thawing, or abrasion. Chemical weathering changes the composition of the rock, while physical weathering only breaks the rock into smaller pieces.
What changes a rock's composition?
Chemical Changes
How are machanical and chemical weathering different?
Mechanical weathering is a process which physically changes the appearance of a rock or structure. Chemical weathering is a process which changes the chemical composition of a rock or structure.
What kind of weathering changes the composition of a rock?
Chemical weathering changes the composition of a rock by breaking down minerals through chemical reactions with water, oxygen, acids, or other substances. This process can alter the rock's mineral composition, leading to the formation of new minerals or the dissolution of certain minerals.
What Type of weathering that changes composition of material?
Chemical weathering changes the composition of materials through processes like oxidation, hydrolysis, and dissolution. These processes break down minerals into new substances, altering the chemical composition of the rock.
Does mechanical weathering change a rocks chemicals?
Mechanical weathering does not change a rock's chemical composition; it only breaks the rock into smaller pieces. Chemical weathering, on the other hand, alters a rock's chemical composition through processes like oxidation, hydrolysis, and dissolution.
What changes composition of rock?
I believe you are looking for the word "metamorphism".
What is weathering that does not alter the chemical composition of the rock called?
The type of weathering that does not alter the chemical composition of the rock is called physical weathering. The acid weathering usually alter the chemical composition of a rock.
What characteristics determines the chemical composition of an igneous rock?
An igneous rock is any crystalline or glassy rock that forms from cooling of a magma. Color and texture help determine the chemical composition of the rock.
How chemical weathering affect rock?
Chemical weathering affects rocks rain, wind or ice . Chemical weathering is the process that changes the composition ( the inside) of rocks on the earth surface.
Rocks that differ greatly from their parent rock have what characteristic?
A high metamorphic grade
When rocks go through the rock cycle do they experience physical and chemical changes?
Yes, rocks in the rock cycle can undergo both physical and chemical changes. Physical changes involve processes like weathering, erosion, and pressure, which can break down rocks into smaller pieces or change their shape without altering their composition. Chemical changes involve processes like melting, crystallization, and metamorphism, which can alter the mineral composition of rocks through reactions with fluids or heat and pressure.
What takes place when the composition of the rock changes?
it undergoes transformation into another rock.
