Because of the Earths shape and the way the Earth is tilting towards the sun.
solar radiation throughout the year. As a result, air at the equator is heated, causing it to rise and creating low pressure. This warm air then moves towards the poles, where it cools, becomes denser, and sinks back towards the surface.
As air becomes warmer it becomes less dense (as long as the pressure remains constant)
Balloons float over a vent because the air coming out of the vent is warmer and less dense than the surrounding air. This creates a buoyant force that pushes the balloon upward, causing it to float.
Frontal wedging
the spin of the earth forces the water centrifugal force) to the equator in a bulge.. although it raises sea heights it does not make it more dense ...water cannot be compressed and made more dense
the air is warmer because the sun's rays hit the equater more directly and because it is warmer it becomes more dense
Air becomes more or less dense relative to its temperature. Cold air is denser than warm. Since the equatorial region is tropical, the air will be warmer and less dense.
El Nino waters are less dense because the waters are warmer and warm water is less dense than cool water. Also, it constantly rains over the ocean during the El Nino, and rain water is less dense than ocean water.
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.

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 air is pushed up
Warmer things are less dense, so as the molasses gets warmer, it becomes less dense or more "liquidy."
Because the molecules in cold air are more tightly packed together than warm air.
As air becomes warmer it becomes less dense (as long as the pressure remains constant)
yes
When dense,cold air meets less dense,warmer air, the warm air is pushed up
