1. Chapter 1 Section 2 Atmospheric Heating

2. Radiation The sun’s energy comes to us as radiation Radiation is the transfer of energy in waves This energy drives the Earth’s weather and makes Earth habitable

3. Thermal Conduction The transfer of energy as heat through a material Heat always transfers from warm areas to cold areas The warmth of the Earth’s surface warms the lowest levels of the atmosphere

4. Convection The transfer of thermal energy by the circulation or movement of a liquid or gas Warm air rises and cooler air sinks to replace the rising air The process continually repeats and a circular pattern in the atmosphere forms This pattern is called a convection current

5. Greenhouse Effect The process where the Earth’s atmosphere holds in just enough heat to keep the planet warm Energy is allowed to enter and exit the atmosphere in balance

6. Global Warming Theory that pollution is making the atmosphere thicker Heat can no longer escape the atmosphere and the planet is becoming warmer A warmer Earth leads to negative effects on planet
