What is the type of weathering that involes a chemical change in some of the minerals in a rock?
Chemical weathering is the type of weathering that involves a chemical change in some of the minerals in a rock. This process breaks down the rock into smaller pieces by altering its mineral composition through chemical reactions with substances like water, oxygen, or acids.
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 is the breakdown of rocks and minerals into smaller particles without a change in composition called?
The breakdown of rocks and minerals into smaller particles without a change in composition is called physical weathering. This process occurs through various natural mechanisms, such as freeze-thaw cycles, abrasion, or the effects of temperature changes. Unlike chemical weathering, which alters the chemical structure of the materials, physical weathering maintains the original composition of the rocks and minerals.
Does chemical weathering change the chemicals in rocks?
Yes, chemical weathering alters the minerals and compounds in rocks by breaking them down through processes like dissolution and oxidation. These changes can result in the formation of new minerals and compounds as the original rock material is chemically transformed over time.
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.
How does weathering change a rock?
particles of its minerals are carried away
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.
The breakdown of rocks and minerals into smaller particles without a change in composition is called?
Physical weathering.
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.

Chemical weathering is the type of weathering that involves a chemical change in some of the minerals in a rock. This process breaks down the rock into smaller pieces by altering its mineral composition through chemical reactions with substances like water, oxygen, or acids.

No. Chemical weathering results in a change of the chemistry of the rock and the minerals therein.
What weathering alters the internal structures of minerals by removing or adding elements?
Chemical weathering alters the internal structures of minerals by removing or adding elements. This process involves the breakdown and decomposition of minerals through chemical reactions with water, gases, or other substances in the environment. Over time, it can change the composition and physical properties of minerals.
Which type of weathering causes the mineral composition of rock to change?
mechanical weathering

Unlike chemical weathering, which alters the chemical structure of the materials, physical weathering maintains the original composition of the rocks and 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.
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.
How does weathering change the appearance of rocks?
Exposure to sunlight can affect the color of some minerals that are present in rock. Because conditions of temperature and pressure change as a body of rock nears the surface, fracturing may occur and minerals which were formed in a different environment can undergo a chemical transformation into new minerals with a different appearance. Rain and groundwater can cause dissolution or oxidation of minerals in rock as well, altering their surface appearance. The main effect of weathering is in the size of a body of rock. They become smaller and typically more rounded.
