Sand is a granular material composed of finely divided rockand mineral particles. It is defined by size, being finer than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass.[1]
The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastalsettings is silica (silicon dioxide, or SiO2), usually in the form of quartz. The second most common type of sand is calcium carbonate, for example, aragonite, which has mostly been created, over the past half billion years, by various forms of life, like coral and shellfish. For example, it is the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years like the Caribbean.
Sand is a non-renewable resource over human timescales, and sand suitable for making concrete is in high demand.[2] Desert sand, although plentiful, is not suitable for concrete, and 50 billion tons of beach sand and fossil sand is needed each year for construction.

Answer:
so baicihly your not allowed to do this at test time boy
Explanation:
no because Separation of oxygenated and deoxygenated blood in the heart of three types of animals. The three-chambered frog heart mixes oxygenated and deoxygenated blood in the ventricle. Therefore, the body never receives fully oxygen-rich blood.
These three (3) chemical reactions include Hydrolysis, Carbonation, and Oxidation.
• Hydrolysis is a chemical reaction caused by the water in which water responds with the rock and changes the size and chemical arrangement of the minerals that reduces opposition to weathering.
• Carbonation is an involvement of water with carbon dioxide to create carbonic acid. It appears when the rock minerals respond with fragile carbonic acid made when water associates with carbon dioxide in the air that deeds on the rock by breaching and disbanding the mineral substances.
• Oxidation is recognized as rusting, a procedure whereby the rock minerals misplace one or more ions or atoms in the occurrence of oxygen. Once minerals in the rock rust it will develop less opposition to weathering. The oxygen associates with other constituents via oxidation method given that rise to ion or atom lose.
Answer:
The first three are the correct choices. The last is wrong
