-The manage found in the tropical oceans is responsible for the movement of atmosphere and the come ocean over most of the globe. The vigour source that drives this pump is solar radiation from the sun.-The second pump is the deep ocean circulation which is also impelled by the sun.-The third pump is the heating of the earths inside by radioactive decay and radiation of heat causes plate plate tectonic theory 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 billet pressure argonas to low pressure areas horizontally due to horizontal differences in pressure.-As a nerve pathway of air warms up it becomes more buoyant and the air rises. Warmer air has less density.-Pressure differences among air masses are typically think 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 more thinly per unit area at the equator than at high latitudes. -The incoming solar radiation varies with latitude and seasons, whereas the asidegoing terrestrial radiation depends on the temperature at the surface and atmosphere. -Primary causes for temperature distribution on earth are because its warmer at the equator and colder at higher latitudes.-The solar radiation cloaked at the surface varies with cloud cover and atmospheric absorption. -Heated air rises at the equator causing air to move towards the equator. This converging air makes up the intertropical convergence zone. -Rising air cools which causes it to loose its water in the urinate of rain. -Areas of rising air cause low pressures. -The warmer stratosphere acts as a barrier to the rising warm air causing it to spread out and diverge. As the air diverges it becomes more and more cooler and it sinks at 30 degrees N/S of the equator (Hadley Cell)-Most of the earths deserts are located at about 3 0 degrees N/S of the equator. fall air causes an area of high pressure at this 30 degrees N/S-Hadley Cell the convergence occurring in the tropics and divergence nigh 30 degrees N/S of it is called the Hadley Cell.-The Hadley Cell and the ITCZ are not constant around the globe. -The equatorward-moving cold air meets the warm air moving poleward from the semitropics producing a zone of steep temperature gradients called the polar front zone at approximately 60 degrees N/S latitude.
