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.

Group the terms according to the subatomic particle they describe.
LiRa [457]

Answer:

This question is incomplete

Explanation:

This question is incomplete but the completed question can be seen in the document attached.

There are three main subatomic particles namely electrons, protons and neutrons. However, the question only discusses two of them; electrons (negatively charged) and protons (positively charged).

A. Found in all matter

Answer: They are <u>both</u> found in all matter since all matter are made up of atoms and all atoms have both protons and electrons (and even neutrons).

B. Negative charge

Answer: The subatomic particle with negative charge (as discovered by R.A Millikan) is the <u>electron</u>

C. Exists in the nucleus

The subatomic particles found in the nucleus are the <u>protons</u> and neutrons.

D. Attract opposite charges

They <u>both</u> (protons and electrons) attract opposite charges because they are of opposite charges and generally unlike charges attract.

E. Moves at extreme speed

Of the two subatomic particles mentioned, <u>electrons</u> move faster than protons because of there lighter mass when compared to the protons. However, the fastest subatomic particle is the neutrino.

F. Bound by strong force

The <u>protons</u> are bound by strong nuclear force which binds them to the nucleus of the atom.
