What is the process that changes the characteristics of a rock?
The process that changes the characteristics of a rock is called metamorphism. This involves changes in temperature, pressure, and the presence of chemically active fluids, which can alter the mineral composition and texture of the rock. Metamorphism typically occurs deep within the Earth's crust.
What is the changes of the appearance structure and the composition of a rock?
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
When sedimentary rock is changed by heat or pressure it forms what?
When sedimentary rock is changed by heat and pressure, it forms metamorphic rock. This process is known as metamorphism, where the existing rock undergoes changes in mineral composition and texture without melting.
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.
What is a rock mineral?
It is a mineral or a number of minerals which are part of the composition of rock.
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.

The mineral composition of the oceanic crust is similar to the composition of what rock?
The mineral composition of the oceanic crust is similar to the composition of basalt rock. Basalt is a type of volcanic rock that contains minerals such as feldspar, pyroxene, and olivine, which are also commonly found in the oceanic crust.

What is the chemical make up or mineral content a rock is made of?
Each rock has a different composition.
What intrusive igneous rock has the same mineral composition as basalt?
Gabbro is an intrusive igneous rock that has the same mineral composition as basalt. Both rocks are composed primarily of plagioclase feldspar and pyroxene minerals.
What is the process in which a mineral changes composition during metamorphism's called?
recrystallization
What type of weathering changes the mineral composition of rocks?
Chemical weathering changes the mineral composition of rocks by altering the chemical composition of minerals through processes like hydration, oxidation, and dissolution. This can result in the breakdown of minerals and the formation of new minerals.

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.
