Earth is made up of many different materials. How do the different materials that make up the Earth affect the absorption of light waves and the heating of the Earth?

• Last week we observed how different materials absorb, reflect and transmit light.
• Many materials absorb light from the sun which can be understood through observing changes in the temperature of the material.

Today’s goal: Explain how light waves
interact with matter, especially Earth materials, and how light energy from the sun heats the Earth.
