Connections What these have in common?
The origin of all of our Energy on Earth • Is of course.. • Our Sun • Click When a gas is heated, it becomes less dense and rises. The colder gas sinks.
Uneven heating of Earth • Uneven heating causes high and low pressure. Winter Summer
Remember this principle • Always, always, always • Warm air less dense, cold air more dense • Warm air rises, cold air sinks
Poof • The warmer the air, the more water it holds • Why does hair do this when you go outside sometimes? • Humidity is the amount of water in the air.
Cold air=high density=high pressure • Hot air=low density=low pressure
Uneven heating of Earth • Uneven heating causes high and low pressure. Winter Summer
Uneven heating • Pressure differences make wind and create weather!
