2. What makes a planet habitable?
What criteria do astronomers use to gauge if an newly discovered exoplanet is habitable?

3. Why is insolation so important?

4. INSOLATION! Insolation Break down the word! In – incoming sol – solar
ation- radiation
INSOLATION!

5. Interaction of Insolation with the Environment
Insolation interacts with the environment in three main ways:
Absorption
Reflection
Scattering

6. The Interaction of Earth’s Atmosphere with Insolation

7. The Greenhouse Effect
Insolation penetrates Earth’s atmosphere and gets absorbed by Earth’s surface
The Earth re-radiates energy in the form of infrared, long wavelength radiation.
Greenhouse gases (H2O(v), CO2, CH4) absorb some of the outgoing radiation.
