PPT-Unit 5: Energy The Transfer of Energy between the Sun, Earth’s Surface and our Atmosphere

On Earth there are three methods of heat transfer Where does Earths energy come from The temperature measured at Earths central core 6000C is actually inferred to be hotter than the . Sunrise . from space over the South China Sea. An astronaut would see something like this; clearly defined bands of color through the atmosphere as the sun rises. High-peaking cumulus clouds, topping out in anvil-head cirrus can be seen as black shadows against the sunlit horizon. The brightness of the colors in the atmosphere in this photograph is due to the amount of dust in the atmosphere. More dust is found in near the equator. There are various sources for such upper level dust. Many dust storms in Africa and ash clouds from major volcanic eruptions are two reasons. .

HEAT ENERGY TRANSFER AND AIR TEMPERATURE As we have seen, Earth’s Weather and Climate are the results of the intricate interrelationships between the Earth and the Sun, and between the components of our Atmosphere and In fact, the atmosphere receives very low amount of heat energy from the sun as it receives most of its energy from the long wave terrestrial radiation.. Atmosphere receive energy from the sun and the earth in different ways. . c.. 70 km (. c.. 43 mi), characterized by a relatively constant composition of its component gases.
