(Wind)
A sand dune will always move with the prevailing wind (downwind). It would not be able to move into the direction of the prevailing wind (upwind).
the earth
wind can move and carry away the tiny particles of soil, which carries
It can move away rock, etc.
Coriolis effect and difference in heat
Heat from the sun is the original cause of the wind, helped by the rotation of the earth. Energy from geothermal comes from the heat under the surface of the earth.
wind
No. Heat does move with the wind, but the wind is not mostly towards the poles, as this map demonstrates. The winds going towards the equator all bend to the West because of the Coriolis effect.
This wind is usually caused by convection currents and is usually strong enough to move entire sand dunes. Air is unstable when heated, and this instability in the air will cause the mixture of higher winds in the troposphere with winds in the lower atmosphere, producing strong surface winds.
Wind energy spins turbines producing electricity.
