Document Summary

Being able to fry an egg on surface example, what does it mean. Temperature is the measure of the average speed of molecule movement in a substance (how quickly molecules are moving) Faster movement for higher temperatures and slower movement for lower temperatures. Kelvin: based on the concept that 0 degrees is set to an energy state in which there is no molecule movement. i. ii. Temperatures are warmer at the equator than near the poles i. Sphere: the equator has a higher density of energy i. ii. Sphere: the equator has a higher density of energy than higher latitudes. Earth is tilted: orbiting around sun, which gives us seasons, the amount of radiation changes in different times of year. On the equator, the difference of temperatures change over seasons is little. On the poles, the difference of temperatures change over seasons is big. Heat will transfer from faster moving molecules to slower moving molecules b.
