Is sand macromolecule or network solid? Thank you

A macromolecule is a molecule with lots and lots of atoms. (i.e. protein, nucleic acid...)
A network solid is is a chemical compound where the atoms are "bonded by covalent bonds in a continuous network extending throughout the material."
A single grain of sand consists of, on average, ~50,000,000,000,000,000,000 atoms.
That's A LOT.
However, these atoms do bond in network covalent bonds.
But that means it's a covalent network solid.
The short answer is that sand is both a macromolecular substance as well as a covalent network solid, so I would go with it's macromolecular but you can interpret that the way you want.

Answer:

a one rotation of the planet on its axis

Explanation:

The two types of motion that planets undergo are;

1) rotation of the planet about its axis

2) revolution of the planet around the sun.

In every planet there are days as shown in the image attached to the question. However, the length of day in each planet is determined by the time required for the planet to complete one rotation on its axis.

It takes the earth 1 earth day (24 hours) to complete rotation on its axis.

The Big Five personality traits are extraversion (also often spelled extroversion), agreeableness, openness, conscientiousness, and neuroticism. Each trait represents a continuum. Individuals can fall anywhere on the continuum for each trait. The Big Five remain relatively stable throughout most of one's lifetime.
