Dive into the interconnected world of Earth's energy sources, from the powerful Sun to the principles of heat and pressure. Learn how unequal heating creates weather patterns, understanding the link between temperature, humidity, density, and pressure. Discover the science behind why warm air rises, cold air sinks, and how these factors shape our climate and weather systems.

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!
