Answer:
Scientists define density as the mass of a substance per unit volume. The word “per”
signals that thinking about density requires thinking about a relationship. It is the relation
between the mass (or weight) of one unit of a material and the volume of that one unit.
Density cannot be directly perceived or measured. It must be inferred from the
relationship of the mass and volume. However, it can be determined by calculation
which is how many schools teach it. To calculate density, you first measure the weight
and volume of an object precisely, then you divide the mass by the volume (i.e. d=m/v,
density equals mass divided by volume). So for example, the density of water is 1 gram
per cubic centimeter because a volume of 1 cubic centimeter of water has a mass of 1
gram. A substance which has a mass of greater than one gram per cubic centimeter
has a density greater than 1.0 gram per cubic centimeter; a substance which has a
mass of less than one gram per cubic centimeter has a density of less than 1.0 gram
per cubic centimeter.

Answer: Warm air rises, creating a low pressure zone; cool air sinks, creating a high pressure zone. Air that moves horizontally between high and low pressure zones makes wind. The greater the pressure difference between the pressure zones the faster the wind moves. Convection in the atmosphere creates the planet's weather.
