Heat Transfer and Energy Budget

Why is the sun important in the formation of most energy sources on earth?

• Warms the earth

• creates wind

• creates the water cycle

• keeps the earth from freezing

What is infrared light?

• Invisible light detected as heat

• Invisible light that causes sunburns, skin cancer, and eye damage

• Light that we can see. ROYGBIV

What is ultraviolet (UV) light?

• Invisible light felt as heat

• Invisible light that causes sunburns, skin cancer, and eye damage

• Light we can see. ROYGBIV

What 3 types of radiation make up solar radiation?

• Radio waves, sound waves, and thermal radiation
• Gamma rays, X-rays, and microwaves
• Alpha particles, beta particles, and neutron radiation
• Ultraviolet (UV), visible light, and infrared (IR) radiation

Is the earth's surface heated equally?

• Yes

• No

What causes wind?

• Uneven heating of the Earth's surface

• Being close to the equator

• The water cycle

• Conduction

What causes the greenhouse effect?

• Excess carbon dioxide and other gases entering our atmosphere

• Excess carbon dioxide and other gases leaving our atmosphere

• Heat escaping the atmosphere

• Not enough carbon dioxide in the atmosphere

What is conduction?

• Heat transfer through space

• Heat transfer through touch

• Heat transfer through currents

What is convection?

• Heat transfer through space

• Heat transfer through touch

• Heat transfer through currents

What is radiation?

• Heat transfer through space

• Heat transfer through touch

• Heat transfer through currents
