Geostrophic winds blows parallel to the isobars. That is because the Coriolis force and pressure gradient force ( PGF ) are in balance. But near the surface the friction can act to change the direction of the wind and to slow it down. Coriolis force decreases at the surface and PGF stays the same. The difference in terrain conditions affects how much friction is exerted. Hills and forests force the wind to change direction more than flat areas. Answer: Friction reduces the speed so Coriolis is weakened.
<h2>
Answer: Pressure</h2>
<u>Pressure</u> is the force
exerted by a gas, a liquid or a solid on a surface (or area)
.
Its unit according to the International System of Units is Pascal
which is equal to
and its formula is:
Answer:

Explanation:
Given that


Emissivity of surfaces(∈) = 1
We know that heat transfer between two surfaces due to radiation ,when both surfaces are black bodies

So now by putting the values



So rate of heat transfer per unit area

Its called static friction.
