SOLAR SYSTEM

Detailed explanation-1: -Movement of air caused by temperature or pressure differences is wind. Where there are differences of pressure between two places, a pressure gradient exists, across which air moves: from the high pressure region to the low pressure region.

Detailed explanation-2: -Density is directly proportional to pressure and indirectly proportional to temperature. As pressure increases, with temperature constant, density increases. Conversely when temperature increases, with pressure constant, density decreases.

Detailed explanation-3: -Even with disruptions like weather fronts and storms, there is a consistent pattern to how air moves around our planet’s atmosphere. This pattern, called atmospheric circulation, is caused because the Sun heats the Earth more at the equator than at the poles. It’s also affected by the spin of the Earth.

Detailed explanation-4: -This change in pressure is caused by changes in air density, and air density is related to temperature. Warm air is less dense than cooler air because the gas molecules in warm air have a greater velocity and are farther apart than in cooler air.

Detailed explanation-5: -Wind is the movement of air, caused by the uneven heating of the Earth by the sun and the Earth’s own rotation.

Detailed explanation-6: -The air’s density depends on its temperature, its pressure and how much water vapor is in the air.

Detailed explanation-7: -At the surface, winds flow counterclockwise (cyclonically) around low pressure, and clockwise (anticyclonically) around high pressure.
