Properties of the Jovian Planets
Compared with terrestrial planet, the giant planets, or Jovian planets are: 1. Bigger in
size, 2. More massive, and 3. Have a lower average density. (Jupiter, Saturn, Uranus,
Jovian planets also have rings
1. Stellar occultation occurs when planet eclipses a star in the sky. The star disappears
behind the planet and then re-appears a short while later. Since we know the relative
speeds of earth and the giant planets we can calculate the size of the eclipsin
Potassium is a solid (metal) at room temp. it is very common in all types of rocks
Argon is a gas at room temp, it is not supposed to be found in rocks, because rocks
solidify when they are hot
Potassium-40 is a rare isotope of potas

Tectonics happen when parts of a planetary lithosphere (also called plates) are moving
in different directions
