What is the chemical makeup of a rock called?

The chemical makeup of a rock is typically referred to as its mineral composition. Rocks are composed of minerals, which are naturally occurring inorganic compounds with a specific chemical formula and crystal structure. Minerals are the building blocks of rocks and determine their physical properties.


What is the composition of the Earth's atmosphere makeup?

The Earth's atmosphere is mainly composed of nitrogen (about 78) and oxygen (about 21), with trace amounts of other gases like argon, carbon dioxide, and water vapor.


What indicates the chemical makeup of a substance by showing how many of each kind of atoms is present in a molecule?

That would be called chemical analysis. If you just want to know what the compound is, that is a qualitative analysis, and if you want to know exactly how much of it you have, that is a quantitative analysis.


What is all of Earth's water makeup?

Earth's water makeup consists of approximately 97% saltwater, found in oceans and seas, and around 3% freshwater, found in glaciers, ice caps, rivers, lakes, groundwater, and in the atmosphere as water vapor. The majority of Earth's freshwater is stored in ice caps and glaciers.


How are mechanical weathering an chemical weathering different?

Mechanical weathering involves physical processes that break down rocks into smaller pieces, such as freeze-thaw cycles or root growth. Chemical weathering involves chemical reactions that alter the composition of rocks, like oxidation or dissolution. Overall, mechanical weathering physically breaks down rocks, while chemical weathering changes their chemical makeup.
