Answer:
1. When temperature is increased, air molecules mover faster and bounce further apart, therefore, higher temperature result in lower air density.
2. When depth is increased, the density increases. Going deeper in depth causes pressure to increase.
3. Latitude does not have a direct effect on density.
4. Salinity Affects Density When salt is dissolved in fresh water, the density of the water increases because the mass of the water increases
