- The pump found in the tropical oceans is responsible for the movement of air and the surface ocean over most of the globe. The energy source that drives this pump is solar radiation from the sun.
- The second pump is the deep ocean circulation which is also driven by the sun.
- The third pump is the heating of the earth's interior by radioactive decay and radiation of heat causes plate tectonics and continents to move. This long term pump has ceased in Mars.
- The winds and ocean currents redistribute the energy received from the Sun
- Air moves from high pressure areas to low pressure areas horizontally due to horizontal differences in pressure.
- As a parcel of air warms up it becomes more buoyant and the air rises. Warmer air has less density.
- Pressure differences among air masses are typically related to the distribution of surface temperatures
- The radiation reaching the Earth is spread over larger and larger areas as we move from the equator to the poles. You get......
