What is the type of weathering that involes a chemical change in some of the minerals in a rock?
Chemical weathering
Does mechanical weathering change a rocks chemicals?
No, not at all. Chemical weathering changes the molecular composition of minerals, but mechanical weathering only changes its shape or outward appearance.
Are chemical sedimentary rocks made of the same minerals?
No. Chemical weathering results in a change of the chemistry of the rock and the minerals therein.
What kind of weathering often affects rocks that are made of different minerals?
Diffrent weathering
What does the chemical weathering of feldspar produce?
clay minerals
What is the type of weathering that involes a chemical change in some of the minerals in a rock?
Chemical weathering
How does weathering change a rock?
particles of its minerals are carried away
What is it called when chemical reactions dissolve the minerals in rock or change them into different minerals?
It's called dissolution, a form of chemical weathering.
Why does the color of granite never change?
The colour of granite does in fact change. For example it will change during the weathering process where feldspar minerals will change to clay minerals such as kaolinite. If the degree of weathering is high this can significantly alter the colour of the granite.
Does mechanical weathering change a rocks chemicals?
No, not at all. Chemical weathering changes the molecular composition of minerals, but mechanical weathering only changes its shape or outward appearance.
Chemical weathering occurs when minerals in rocks are changed chemically. Which of these will most likely change the rate of chemical weathering on a rock?
rainfall and temperature
Are chemical sedimentary rocks made of the same minerals?
No. Chemical weathering results in a change of the chemistry of the rock and the minerals therein.
The breakdown of rocks and minerals into smaller particles without a change in composition is called?
Physical weathering.
What is the silicate mineral that originates as a product of chemical weathering?
Clay minerals are the product of chemical weathering of silicate minerals, such as feldspars. Clays are silicate minerals.
How do water and air help cause chemical weathering?
When minerals come into contact with air and water, some dissolve and others react and change into different minerals.
In terms of rock cycle why do minerals and rocks change over time?
They change because of exposure to weathering, erosion, heat, pressure, and melting.
A type of chemical weathering in which minerals react with dissolved oxygen in water is known as?
Physical weathering is a type of weathering in which minerals react with dissolved oxygen in water. This causes chemical changes to take place in the minerals.
