How can unequal heating in the atmosphere cause wind?

Answer 1

AnswerMost differences in air pressure are caused by unequal heating of the atmosphere. As you learned in the previous section, convection currents from when an area of Earth's surface is heated by sun's rays. Air over the heated surface expands and becomes less dense. As the air gets less dens, it's a pressure decreases. If a nearby are is not heated as much, the air above is the less heated area will be cooler and denser. The cool and dense air has a higher pressure so it flows underneath the less dense air. This process causes warm air to rise.

Answer 2

It causes air movements in the troposphere: Near the equator, where the sun's irradiation heats the strongest, air moves upwards (causing low pressure and tropical rainfalls there), then away from the equator northwards and southwards, then comes down again (causing high pressure and dry climate in latitudes such as in the Sahara desert), and then moves back towards the equator from the high pressure latitudes towards the equatorial low pressure latitudes, causing winds from north to south in the north of the equator and winds from south to north in the south of the equator on the earth's surface. There are further analogous planetary air rolls towards the north and the south: at the poles cold air sinks downwards, and there is an upward air movement around 60° latitude. All of these wind patterns shift in position along with the seasonal change of the sun's position.

Answer 3

Uneven heating of a region can cause a pressure differential, as hot air is less dense than cold air. This can result in pressure fronts you commonly see referred to as high and low. This can push air in various directions and cause different weather conditions.

Answer 4

Wind is caused by unequal heating of the atmosphere by the sun. Most differences in air pressure are caused by unequal heating of the atmosphere. As you learned in the previous section, convection currents from when an area of Earth's surface is heated by sun's rays. Air over the heated surface expands and becomes less dense. As the air gets less dens, it's a pressure decreases. If a nearby are is not heated as much, the air above is the less heated area will be cooler and denser. The cool and dense air has a higher pressure so it flows underneath the less dense air.

Answer 5

Unequal heating in the atmosphere causes temperature variations which in turn lead to differences in air pressure. This pressure difference sets air in motion, resulting in wind as air moves from high to low pressure areas to equalize the pressure gradient.

Answer 6

The unequal temperatures create currents of rising warm air, and descending cold. All of which creates flowing currents of air that are the winds.

Answer 7

because it is cooling
