What causes the unequal temperature in air?

Answer 1

The primary effect of heating a gas is lowering the density of the gas, making it lighter. Uneven heating of gas creates local density gradients, which will drive bulk movement of the gas via natural convection to get rid of the local density gradients.

Answer 2

Unequal heating causes different wind patterns and changes the weather and climate a lot. Water has the highest specific heat of all substances
The unequal heating of the air causes the pressure variances.

Answer 3

All materials conduct heat at varying rates. Thermal insulators tend to be very slow conductors, while materials like copper and water easily conduct heat. However, since no signal (including the transfer of heat) can travel infinitely fast, it is impossible to uniformly heat any material with a localised source of heat. The only way to uniformly heat a material would be to uniformly raise the temperature at all points at once. But even this is not practical for materials of significant thickness because it would take time for heat to conduct into the centre of the material. The faster you try to raise the temperature, the worse is localisation. Slowly raising the temperature will allow near-thermal equilibrium.

Answer 4

During daytime, air over the land is warmer than air over oceans. The warm air rises, causing air pressure over the land to decrease. The cooler air over the sea rushes toward the land where air pressure is lower; this is known as sea breeze.

During night, since land loses heat rapidly, air over the land is cooler than that over the sea. The air over the sea rises as air from the land rushes toward the sea where air pressure is lower; this is known as land breeze.

Answer 5

One cause could be that land is under some air and water is under other air; when the sun rises, the land heats up faster and the air above it is warmed.

Answer 6

a convection current!!
