it isn't correct to say it rises or falls. A better way to ask the question is: "Why do hot things (like hot air) rise above cold things (like cold air)?"
To answer this question, it is important to understand what heat is.
Heat is energy. When we say something is hot, we really are saying it has a lot of stored
energy.What does this energy do?
Matter is made up of incredibly small pieces called atoms and molecules. Atoms and molecules are always moving.
The more energy these atoms and molecules have, the faster they move. The faster they mover, the more space they take up.
If something is hot, it weighs the same as if it were cold, but it just takes up more space.
This leads us to the concept of density. Because hat air takes up more space than cold air, hot air has a smaller density. Less dense hot air will "float" above the more dense cold air.

∙ 15y agoGenerally warmer substances, air for example, rises above cooler. The reason is that the heat causes expansion and the air becomes less dense. The cooler air then falls through the warmer layer, pushing it upward.
It is more correct to say that warm air is pushed upward, rather than saying warm air "rises".

∙ 14y agoThe sun provides us roughly 1375 watts per square foot of warmth. The atmosphere manages to capture about 10% of this radiation. This is done through what are referred to now as green house gases.
The most prevalent of these gases is water vapor. This gas collects roughly 80% to 90% of all warmth we trap on the planet.
Second on this list is CO2 (Carbon Dioxide) which collects about 6% of all warmth.
The other gases all make up the remaining few percentages of the warming effect.

Does sun give off more heat in the summer?
No, the sun does not give off more heat in the summer. It only seems hotter because the axis of the Earth, that you are on, is now pointed closer to the sun, where as in winter you are actually farther from the sun, since the axis is pointed in the other direction, and therefore you do not experience the same warmth as in summer.
What four things does the sun give us?
The sun gives us light, it makes our plants grow, it gives us warmth and it gives us energy.
The amount of light and warmth a planet from the sun depends on what factors?
The amount of light and warmth a planet receives depends on their distance from the sun and the atmosphere. If the atmosphere has high levels of Carbon Dioxide, the gases will trap more heat.
What is correct the sun rises from the east or the sun rises in the east?
The Sun rises IN the East.
Why does the temperature tend to drop when the sun goes down and rise when the sun rises?
Because when the sun drops, it is not directly focused on that part of the Earth, and the sun is our source of heat as well. So when the sun is focused somewhere else, so is the heat along with it
What happens to the sun's heat in the greenhouse effect?
The sun's heat (ultraviolet radiation) warms the surface of the earth.Heat rises (infrared radiation) rises from the warm earth.Much of this heat is captured by greenhouse gases which become warm.This warmth makes the surrounding atmosphere warm.It also warms the surface of the earth even further.
How does the sun give off heat?
The warmth you feel come from the Infrared rays.
What does evaporation depend on?
heat warmth the sun get it
What is source of warmth?
God created the sun to give us all warmth.
How do we know that heat can travel through space?
We can feel the warmth of the sun!

Does asteroid produce heat?
asteroids dont produce heat thay get some warmth off the sun
Where does the warmth come from that makes the air expand?
The sun provides heat to the Earth.
Why is the sun important to the sun?
The sun is important to the sun in many ways. First of all, the sun gives off warmth. Some of this warmth will go towards earth, causing the earth to heat up. The heat waves that do not go through the earth's atmosphere will bounce back and hit the sun. This helps give the sun warmth to itself, so it can continue to create more and more heat for the earth. Secondly, if the sun did not exist, then how could the sun see anything? The sun obviously needs light in order to see the earth, so it knows where to aim its heat waves at. If the sun could not see the earth, it would most likely spew its heat waves all across the galaxy, hitting other solar systems, causing them to burn to a crisp. Lastly, the sun needs a companion. Someone to give it encouragement when times are tough. Occasionally, the sun gets sick of creating heat, and simply wants to give up on what it was created for; heat, and warmth, and the major light source during the day, and reflecting its light off the moon's surface to give us our major light source during the night. In these terrible times or hardship, the sun is in dire need for someone or something to encourage it. Luckily, the sun has the sun to help it get through these tough times. We are very fortunate that the sun has something that gives it encouragement. It is possible that the sun may stop working, if it doesn't have something to encourage it every now and again.

What is heat trainsfer?
Heat transfer is when heat is transfered from one object to another,for example,the sun gives the Earth warmth and energy
