Presentation transcript:

Chapter 19: Earth’s Atmosphere

3 methods of energy transfer Radiation (EMR) Conduction (BY TOUCH) Convection (MOVEMENT OF GAS OR LIQUID) 3 methods of energy transfer

Greenhouse effect – “good” & natural global warming “bad”

Latitude vs solar energy

Earth’s orbit affects angle of sun’s rays

How does the atmosphere circulate? Fluids move from high to low pressure Equator moves faster than poles Warm air rises, cold air sinks Earth rotates How does the atmosphere circulate?

Coriolis Effect: curving of moving object’s path b/c of rotation

Coriolis Effect in action

Global winds: set up by Coriolis effect & convection

Jet streams

Local winds caused by uneven heating

Valley breeze – warm air moves up mt. breeze – cold air moves down
