I'll give you 20 points and brainlest answer
1. How is density affected when the temperature increases.
2. How is density affected when the depth increases.
3. How is density affected when the latitude increases.
4. How is density affected when the salinity increases.

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
