Tides. What are they: Tides are daily changes in level of ocean surface. Discovered by Sir Isaac Newton. Causes: Gravitational pull of the moon and sun.

Origin  Several theories  Gravity, same formation material, Earth’s residual material  Most popular – impact/collision theory ** billions of years.

Lunar Atmosphere Atmospheric Pressure: 3 × 10 −15 atm ( times smaller than the Earth’s) ~Nearly a Vacuum~ Sources of atmosphere come from Sputtering: bombardment of solar winds ions that release atoms of Sodium and Potassium Outgassing: Argon – 40, Polonium – 210, and Radon released during radioactive decay in the crust and mantle Capture: of Helium – 4 from the solar wind

What time does the moon at a particular phase rise and set?

Lets do the Moon Dance: A kinesthetic approach to learning the times that the phases of the moon rise, set and are highest in the sky. Rules – Your right hand is the sun – Your left hand is the Moon – To your left is East – To your right is West – The angle between the SUN – EARTH – MOON system must stay constant for a given lunar phase.
