How does convection happen in a room?
Warm air flows toward the ceiling and cool toward the floor. (expansion with heat results in lower density)
How is a density current related to upwelling?
Density currents are warm water rising up, while upwelling is cool water rising. So they're opposites.
If you cut a peice of glass into 4 pieces what would happen to its density?
Nothing would happen to its density.
What will happen if density of ball bearing is less than density of given oil?
answer
What happen when an object whose density is equal to the density of water is dropped in water?
It would sink until it was completely covered with water and then neither go farther down nor up.
When did Warm Up happen?
Warm Up happened in 2000.
When liquid is warm its density?
Its density decreases.
When liquid water is warm its density?
Its density decreases.
How does convection happen?
Liquids and gasses tend to expand when heated, this lowers the density, thus warm "air" rises and cool air falls.

What is the difference in density between warm and cold air?
The density between cold and warm air is, cold air is heavier than warm air.
Do air on the surface of earth warms the density of the air?
I don't know what you mean by "warm the density of the air" but if you mean heat up the air in general, I guess not if it is directly a few inches below the surface, because the earth's core doesn't warm it, and the sun can't warm it.
How is a density current related to upwelling?
Density currents are warm water rising up, while upwelling is cool water rising. So they're opposites.
What will happen to the density of gas if the mass of gas doubles and the volume of the gas is cut in half?
Density would go up 4 times
What will happen to the density of a gas if the mass of gas double and the volume of the gas is cut in half?
Density would go up 4 times
What will happen to the fur thickness of a population of rabbits over time living in a very warm climate?
When a population of rabbits lives in a very warm climate its fur will decrease in density over time, becoming thinner and lighter.
Is the density in warm air high or low?
As temperature increases, density decreases.
