Tides

High tides occur during New Moon and Full Moon phases. Tides are caused by gravitational pull of the moon.

Eclipses

• Solar Eclipse: moon is between earth and sun (New Moon Phase)

• Lunar Eclipse: Earth is between moon and sun (Full Moon Phase)

Moon Phases

• Waxing: amount of lighted portion appears to be increasing

• Waning: amount of lighted portion appears to be decreasing

• Cycle lasts for approximately 30 days

Seasons

• Equinox: Spring and Fall

• Solstice: Summer and Winter

• 1 Revolution = 365 1/4 days = 1 year

• If Southern Hemisphere is tilted towards the sun, it will be summer in the south and winter in the north.

Rotation

• Earth is tilted 23.5 degrees on its axis

• 1 rotation =24 hours = 1 day

• rotates counter-clockwise

• Sun rises in the East, and sets in West.

• Equator: imaginary line around exact center of earth.
