Energy in the Earth’s Systems – How do external and internal sources of energy affect the Earth’s systems?
6.3 - Variations in the amount of the sun’s energy hitting the Earth’s surface affect daily and seasonal weather patterns.
· Local and regional weather are affected by the amount of solar energy these areas receive and by their proximity to a large body of water.

Introduction: Did you ever wonder why waterbeds have heaters? Have you ever wondered how a refrigerator works? Have you ever wondered how an engine works? How can birds stand in icy water without losing a lot of body heat? Why are sidewalks made in sections? Why do large bridges have expansion joints? How do heat pumps work? These questions and more will be answered in this unit.
