6-4 How is Earth's surface heated?
SWBAT: Describe how energy from the Sun warms Earth’s surface.
radiant energy- energy given off by the Sun that can travel through empty space
radiation - transfer of energy through empty space
• The Sun gives off radiant energy that travels through space by radiation.
• When light energy from the Sun is absorbed by matter, it is changed into heat energy.
• Earth’s surface changes light energy from the Sun into heat energy.
• Only a small part of the Sun’s energy reaches Earth’s surface; the rest is absorbed by the atmosphere or reflected back into space.
