What is more resistant to weathering metamorphic or igneous rock?
Metamorphic rocks are generally more resistant to weathering compared to igneous rocks. This is because metamorphic rocks have undergone changes in their mineral structure and texture due to intense heat and pressure, making them more compact and less porous, which helps them resist weathering processes like erosion and chemical breakdown.
Which type of weathering causes the mineral composition of rocks to change?
Chemical weathering is the type of weathering that causes the mineral composition of rocks to change. This process occurs when minerals in rocks react with elements in the environment, causing a chemical reaction that alters the rock's mineral composition over time.
What common mineral is resistant to both physical and chemical weathering?
Quartz is a common mineral that is resistant to both physical and chemical weathering. Its hardness and lack of cleavage make it more durable under mechanical forces, while its chemical composition is less reactive to chemical weathering processes.
What type of weathering that does not change the mineral composition of a rock?
Physical weathering, such as frost wedging or root wedging, does not alter the mineral composition of a rock. These processes break down rocks into smaller pieces without changing their chemical makeup.
What causes physical weathering but not chemical weathering?
Physical weathering is caused by mechanical forces such as temperature changes, frost wedging, and abrasion, while chemical weathering involves the breakdown of rock through chemical reactions like oxidation and hydrolysis. Physical weathering does not change the chemical composition of the rock, whereas chemical weathering alters the mineral structure.
Minerals resistant to chemical weathering?
Quartz is a mineral that is highly resistant to chemical weathering. Marble is a mineral that is more susceptible to chemical weathering.
What is a colourless mineral from igneous rocks used in glass making?
Quartz is a colorless mineral found in igneous rocks that is commonly used in glass making. It is valued for its hardness and resistance to chemical weathering, making it an ideal ingredient for a variety of glass products.
What is more resistant to weathering metamorphic or igneous rock?
Metamorphic rocks are generally more resistant to weathering compared to igneous rocks. This is because metamorphic rocks have undergone changes in their mineral structure and texture due to intense heat and pressure, making them more compact and less porous, which helps them resist weathering processes like erosion and chemical breakdown.
What kind of weathering causes mineral composition of rocks to change?
Chemical weathering

Why is igneous rock so resistant to weathering and erosion?
Igneous rocks are resistant to weathering and erosion because they are formed from cooled magma or lava, which solidifies quickly and has a crystalline structure, making it harder for external forces to break down. Additionally, they generally lack internal pores or weaknesses that would make them more susceptible to weathering. Lastly, the mineral composition of igneous rocks often consists of minerals that are chemically stable and less prone to chemical weathering.
Which type of weathering causes the mineral composition of rocks to change?
Chemical weathering is the type of weathering that causes the mineral composition of rocks to change. This process occurs when minerals in rocks react with elements in the environment, causing a chemical reaction that alters the rock's mineral composition over time.
What common mineral is resistant to both physical and chemical weathering?
Quartz is a common mineral that is resistant to both physical and chemical weathering. Its hardness and lack of cleavage make it more durable under mechanical forces, while its chemical composition is less reactive to chemical weathering processes.
What mineral forms from the chemical weathering of feldspar?
The clay mineral Kaolinite - Al2Si2O5(OH)4.
What is the principal difference between weathering and chemical weathering?
The principal difference between weathering and chemical weathering is that weathering involves physical processes that break down rocks into smaller pieces without changing their chemical composition, while chemical weathering involves chemical reactions that alter the mineral composition of rocks.
What type of weathering that does not change the mineral composition of a rock?
Physical weathering, such as frost wedging or root wedging, does not alter the mineral composition of a rock. These processes break down rocks into smaller pieces without changing their chemical makeup.
