Solar radiation (sunlight) can be emitted, reflected, or absorbed. Match each term to its definition.
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Absorb | arrow_right_alt | to produce or release light |
Emit | arrow_right_alt | to cast back light from a surface |
Reflect | arrow_right_alt | to take up without reflecting |
Part 1: On Greenhouse Effect Waves tab, set greenhouse gas concentration to NONE. Uncheck the CLOUD. Observe the sunlight and infrared energy waves.
What happens to sunlight Energy Waves?
What happens to the infrared Energy Waves?
What is the temperature in Celsius with no greenhouse gases?
Add a cloud by checking the CLOUD box. How does the activity of the sunlight and infrared energy change?
What is the temperature in Celsius with clouds?
Adding clouds the temperature.
Part 2: On Greenhouse Effect Waves tab, set greenhouse gas concentration to LOTS. Uncheck the CLOUD. Observe the sunlight and infrared energy waves.
What happens to sunlight Energy Waves?
What happens to infrared Energy Waves?
Adding greenhouse gases the temperature.
Part 3: Refresh the site and choose the Photons tab. Select the CALENDAR button, then select the ice age, 1750, and 2020 tabs and record the greenhouse gases and temperature for each period.
ppm = Parts per million
ppb = Parts per billion
Ice Age 1750 2020
