Changes in the appearance structure and composition of a rock can occur due to weathering, erosion, and metamorphism. Weathering can break down the rock into smaller pieces, while erosion can transport these pieces to new locations. Metamorphism can alter the mineral composition and structure of the rock through heat and pressure, resulting in the formation of new minerals and textures.

What changes a rock's composition?
Chemical Changes
Type of change that happens when you break a rock or freeze water?
Physical change: breaking a rock changes its physical appearance without altering its chemical composition. Freezing water involves a physical change where the water molecules rearrange to form a solid structure, without any change in the chemical composition of water.
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.
When a rock metamorphoses physically what often results?
When a rock metamorphoses physically, it typically undergoes changes in texture and mineral composition due to heat, pressure, or chemically active fluids. This process can lead to the formation of new minerals and the realignment of existing ones, resulting in a foliated or non-foliated structure. Common examples include the transformation of limestone into marble or shale into schist. These changes enhance the rock's durability and can significantly alter its appearance and properties.
What can extreme pressure and temperature do to a sedimentary rock?
Extreme pressure and temperature can alter a sedimentary rock by causing it to metamorphose into a new rock type known as metamorphic rock. This can lead to changes in mineral composition, texture, and structure of the original sedimentary rock.
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.
How do the properties of a rock change when the rock changes to metamorphic?
When rock changes into metamorphic rock, its appearance, texture, crystal structure, and mineral content change.
How do the properties of a rock change when the rock changes to a metamorphic?
When rock changes into metamorphic rock, its appearance, texture, crystal structure, and mineral content change.
What are the two changes of a rock of metamorphism?
When rock changes into metamorphic rock, its appearance, texture, crystal structure, and mineral content change.
How do the properties of rock change when the rock change to metamorphic?
When rock changes into metamorphic rock, its appearance, texture, crystal structure, and mineral content change.

What does rock composition mean?
Igneous rock composition basically means how the rock would look if you were to cut it in half. In the case of igneous rock, you would see the different layers of rocks that have melted with it.

What does metamorphosis rock mean?
Metamorphosis rock refers to a type of rock that has undergone significant changes in appearance, structure, or composition due to high pressure, temperature, or chemical processes within the Earth's crust. This transformation typically involves recrystallization of minerals, resulting in the formation of new rock types such as marble from limestone or schist from shale.
All changes in the original shape and or size of a rock body are called?
All changes in the original shape and size of a rock body are called deformation. This includes processes like folding, faulting, and shearing that can alter the appearance and structure of a rock.
What takes place when the composition of the rock changes?
it undergoes transformation into another rock.
