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

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true
