What causes wind?

a differences in air pressure

b decreases in air temperature

c the occurrence of the coriolis effect

d the even heating of earth’s atmosphere

A differences in air pressure

Explanation:

As we know that flow of fluid is always due to pressure gradient.

here we know that pressure difference will apply force on the fluid due to which it has tendency to flow.

The force due to pressure difference is given by

now fluid has always a tendency to flow from higher pressure region to lower pressure region due to this force of pressure difference.

So wind flow is always following the same law of pressure difference due to which wind flows from region of high pressure to low pressure

so correct answer will be

A differences in air pressure

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
