Energy in Earth’s Atmosphere

Conduction: (solid)

• the transfer of thermal energy through direct

• the transfer of thermal energy through electromagnetic waves

• the transfer of thermal energy through the movement of a liquid or gas.

Convection

• the transfer of thermal energy through direct

• the transfer of thermal energy through electromagnetic waves

• the transfer of thermal energy through the movement of a liquid or gas.

Radiation

• the transfer of thermal energy through direct

• the transfer of thermal energy through electromagnetic waves

• the transfer of thermal energy through the movement of a liquid or gas.

B

• Conduction

Electromagnetic waves consist of:

• Magnetic field only.

• Electric field only.

• Both a and b

What explains the energy budget on Earth?

• Earth's surface reflects less energy than the atmosphere

• The atmosphere absorbs more energy than Earth's surface

• Earth's surface absorbs and re-emits equal amounts of energy

Natural process that warms the Earth's surface:

• 
• 
• 

The greenhouse effect supports life on Earth. It is caused when energy from the sun is:

• Reflected by the atmosphere

• Reflected from Earth

• Trapped by the atmosphere
