When moist air is forced upward when blown over mountains what happens low pressure areas over the ocean cause a pressure gradient that draws warm dry air outwards in a clockwise spiral from the high pressure center this dry airmass sweeps across the deserts of eastern toward the coast the winds are known as Santa Ana winds at higher altitudes the surface air is colder but higher in oxygen while the air at the bottom is warmer denser and higher in nutrients as the higher air warms it becomes denser and sinks forcing the air at the bottom to rise this is called turnover it piles up against the highest peaks of the mountains when enough pressure builds up it suddenly spills over the mountains acting much like a damn bursting causing torrential rain on the other side of the mountain this is called a temperature inversion it cools and loses its ability to hold water producing rain on the near side of the mountains the remaining dry air blows to the other side creating a rain shadow on the far side of the mountains

m the oceans when surface water moves away from the coast what happens it is steadily replaced by nutrient rich water moving up from the ocean bottom in a process called upwelling it evaporates causing a humid low pressure system causing a cyclone it cools and loses its ability to carry oxygen the anoxic water sinks along the continental shelf causing upwelling surface water is colder but higher in oxygen while the water at the bottom is warmer denser and higher in nutrients as the surface warms becomes denser and begins to sink displacing nutrient laden water at the bottom in a process called upwelling

Why are the tropics warm and the poles cold Choose the best answer the tilt of the earth makes the poles farther away from the Sun than the equator OO the curvature of the earth slopes away from the Sun towards the poles causing the sun to hit a lower less direct angles as heated air rises at the equator it cools and is less able to hold water producing rain as more air is heated along the equator the cooler ai above Earth s surface is pushed toward the poles the poles are tilted away from the Sun and thus receive a smaller amount of solar radiation per unit area
