heat transfer, density, air pressure,electromagnetic spectrum

How does the density of air change as air is heated of cooled? The density changes by decreasing if it is warm and increasing if it is cooled.
How are density and air pressure related? They are related because the both do with the amount of air.
What 2 things can change the density and pressure of air? The two things that can affect the density and presure are temprature and altitude.
How does heating and cooling affect the movement of air? It affects it becuase when it is warm the air moves quicker and it is less dense, and when the air cools it becomes more dense and it will move slower.
how does land and water heat and cool? Water will heat up slower and cool slower. Soil will heat up faster and cool faster.
When a surface is hot how does the air aroung it change? The air around it uses condustion and heats up, then heats up the other air using convection.
if you are at the beach during the day what will be hotter? sand or water? If you are at the beach durng the day the sand will be warmer then the water.
What is albedo? The amount of light reflected.
