Rocks change in composition when reacting with our surroundings due to processes such as weathering, erosion, and chemical reactions. These processes can be driven by factors like temperature, pressure, and the presence of water or acids, which facilitate the breakdown of minerals and the alteration of their chemical structure. For example, when rocks are exposed to acidic rainwater, minerals can dissolve, leading to changes in their overall composition. Additionally, biological activity, such as the growth of plants and microorganisms, can also contribute to these compositional changes.

What kind of weathering causes mineral composition of rock to change?
Chemical weathering
Is reacting a physical change or chemical change?
Reacting can involve both physical changes and chemical changes. Physical changes involve alterations in the physical state of a substance without changing its chemical composition, while chemical changes involve the formation of new substances with different chemical compositions.
Is oxidizing a physical or chemical change?
Oxidizing is a chemical change, as it involves a substance reacting with oxygen to form new compounds with different properties. In contrast, physical changes do not alter the chemical composition of a substance.
Is reacting with vinegar a physical or chemical property?
Reacting with vinegar is a chemical property because it involves a chemical change where new substances are formed. The reaction between vinegar (acetic acid) and another substance causes a chemical reaction that alters the composition of the original substances.
How do reagent strips change color?
Reagent strips change color by reacting with specific substances present in the sample being tested. This reaction causes a chemical change, resulting in a visible color change on the strip. The intensity of the color change can indicate the concentration of the target substance in the sample.

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 process causes the mineral composition of the rock to change?
The process is called metamorphism, the alteration of chemical composition or structure due to heat and/or pressure.
Is reacting with vinegar a physical or chemical property?
Reacting with vinegar is a chemical property because it involves a chemical change where new substances are formed. The reaction between vinegar (acetic acid) and another substance causes a chemical reaction that alters the composition of the original substances.
Is a piece of ice melting and reacting with sodium a physical or chemical change?
The melting of ice is a physical change, as it changes from solid to liquid without altering its chemical composition. However, when the melted ice reacts with sodium to form a new compound, it is a chemical change because the chemical composition of the substances involved is altered.
Is melting gold a chemical change?
No, melting always is physical.As to the previous answer: reacting gold with an acid is not melting but oxidation.
How can you causes physicals change?
Physical changes are changes affecting the form of a chemical substance, but not its chemical composition.
