The Moon

-Formed by debris from Earth when it was hit by Mars sized planet

-Lunar highlands

-Crater filled


-Fewer craters

-Was thought to be ocean in the past


-Phases of the moon



-Causes tides because of gravitational pull

-We only see one side

-It rotates around the Earth in 29.5 days


-Has a 23.5 degree tilt

-When a hemisphere is tilted towards the Sun, it is summer because is receives more direct rays

-When a hemisphere is tilted away from the Sun, it is winter because it receives less direct rays

-It revolves around the Sun in 365 days


Solar Eclipse

-Occurs when the Sun, Moon, and Earth are in a straight line

-The Moon blocks the Sun's light, and the small shadow falls onto Earth

-Occurs infrequently because the Moon does not revolve around the Earth on the same plane as the Earth orbits the sun

Lunar Eclipse

-Occurs when the Sun, Earth and Moon are in a straight line

-The Earth blocks the Sun's light, and a shadow falls on the Moon
