Why is the air at the tropics always warmer then the air at the poles?

That part of the globe consistently gets the most direct exposure to the sun. We can be very grateful for this. If it were not for our beautiful moon, the earth's movement would be less stable, and the poles would wander (in geological time) to the degree that they would sometimes point toward, or nearly toward, the sun. Some argue that without the moon, conditions on earth would not have allowed for the support of life.

What is warmer cotton or wool?
Wool is generally warmer than cotton, due to the air spaces in wool.
Would you expect high or low air pressure at the poles?
you would expect it to have high pressure
Why is the air temperature near the ceiling of a room tends to be warmer than near th floor?
The hot air is lighter than the cool air so it floats to the ceiling.:)
Can you draw a diagram of a hadley cell?
Yes, warm, moist air rises at the equator and causes cool, dry downdrafts at the tropics (30°N/S).
Define air mass?
A warm air mass that forms in the tropics, and has low air pressure.- UNKNOWN WRITER- This definition is completely correct you can even look in a science book if you don't believe me it will say the exact samething-<3-bye-
When air moves away from the tropics and toward the poles it becomes?
cool and dry
When the air moves away from the tropics and towards the poles it becomes?
cool and dry
When air moves away from the tropics and toward the poles it becomes .?
cool and dry
What are the pressure conditions of the air above poles?
Generally the poles are cold places, receiving Sunlight at a low angle or no Sun at all. This means the air above the poles tends to be cooler than the rest of the planet. Cold air is dense so the pressure of the air at the poles tends to be higher than the rest of the planet. Thus air (cold air) tends to flow away from the polar regions along the Earth's surface to be replaced by light warmer air flowing into the poles at a higher level (this air then cools). There is therefore a general flow of warm air north and south towards the poles from the equator and a flow of cold air from the poles towards the equator. This flow of air spreads out the heat from the Sun, warming the poles and cooling the tropics. In detail this overall flow is restricted by the thickness of Earth's atmosphere and several flow cells form to complete the chain causing Earth's climatic zones.
Why are water and air at the equator warmer than water and air at the poles?
Since the equator is the closest point to the sun on earth,that means the heat from the sun heats up the air and water there more than at the poles
Why is the troposphere thinner at the poles?
As air gets colder it contracts. While the total amount of air is about the same in any column of the troposphere, at the cold poles that column takes up less space, resulting in a shorter distance to the top of the troposphere.
Which type of air front is always forced up?
warmer, less dense air
Water vapor rises because it is?
Vaporized water rises because it is 100 degrees Celsius or warmer and is therefore warmer than the surrounding air and warmer air always rises above colder air.
Where do large scale weather systems develop and why are they important?
Large scale weather systems that transport surface cold air toward the tropics and surface warm air toward the poles.
Along a front which type of air is always forced upward?
Warm air :d
What role does the suns energy has in creating wind?
All the energy on earth comes from the sun , including wind energy . The sun warms the tropics more than the polar regions, so air rises in the tropics and sinks near the poles. This causes a constant current of air in a loop, from the poles towards the equator close to the ground and the other direction higher up. :) hope this helps!
Why does Britain's weather vary so much?
We have a maritime climate. Where the warm wet air from the tropics meets up with the cold dry air from the poles, you get a series of frontal systems that cross the Atlantic from South West to North East. Ireland gets the brunt of it, but these affect the whole of the UK. That's why the weather's always changing and why our countryside is always green.
