Which type of air front is always forced up?
warmer, less dense air
Which rock is made up of less dense minerals like quartz and feldspar?
Granite
Is warm air less dense than cold air and moist air is more dense than dry air?
Warm air is less dense then cold air. But moist air is actually less dense than dry air because water vapor has a lower molecular weight than the oxygen and nitrogen that make up most of the atmosphere.
Can you describe the density changes between the two substances that a lava lamp contains?
The light at the bottom heats up the oil, therefore expanding it and making it less dense. The less dense oil then floats to the top, where the cooler, more dense, oil floats to the bottom.
What can speed up light?
Travelling through a medium that is optically less dense. Vacuum is best.
How does air change the higher up in the atmosphere you go?
It becomes less dense.
Does the body density change in water?
No the density is like a solid like thing,humans,and places.
Why is it harder to breathe the higher you go up in the air?
There's less air. The air is less dense so you are getting less oxygen.
How is the earth like a density column?
Earth is like a density column, because the inner core is the most dense, and it gets less and less dense as you go up top to the crust.
How does air help to make a hot air balloon work?
Air has a certain density. A hot air balloon heats air inside the balloon which causes it to become less dense. This is because the hotter something is, the more space it takes up. Less dense things float on top of more dense things (think of oil on water). You get enough less dense hot air, and the balloon will float up on top of the cold, dense air.
A light was speeds up as it moves from a more dense to a less dense medium?
yes it will !
When dense cold air meets less dense warmer air the air is pushed?
When dense,cold air meets less dense,warmer air, the warm air is pushed up
When dense cold air meets less dense warmer air the warm is pushed?
When dense,cold air meets less dense,warmer air, the warm air is pushed up
When dense cold air meets less dense warm air the air is pushed?
When dense,cold air meets less dense,warmer air, the warm air is pushed up
What effects the layering of earths atmosphere?
the density and temperature of the layers. The farther you go up, the less dense each layer is.
Why does the density of the atmosphere decrease with height?
The Earth's atmosphere declines with altitude.
Why won't a cork stay in place at a bottom of a pool?
it is less dense that the water so it is boyuant and will go up to the surface
