Matter is defined as a substance made up of particles that has weight and can occupy space. There are three main states of matter which include:

Solid: They have their particles vibrate in their fixed positions.
Liquid: The particles are generally slightly further apart than in a solids; and
Gas: particles are widely spaced and tend to be only slightly attracted to each other.
The windsurfer, his board, and his surroundings is made up of particles that are tightly packed together and vibrate in their fixed positions.

Therefore, the components that make up the windsurfer, his board, and his surroundings is matter.

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
