1. The Moon

2. I. Features
a.Craters- billions! Lunar Regolith- moon dust
b.Rays- meteors, comets, asteroids hit the moon forming streaks- can be a thousand miles long!
c.Maria- Dark “seas”, make up 30% of surface- lava that solidified from moon’s crust.
d.Highlands- Look light colored from earth, mountains that are left by giant craters.
e.Rilles- Long, narrow valleys.

II. Moon Phases
a.The moon rotates on its axis 
and revolves around the 
earth. It takes about a month (27 days) for the moon to rotate and revolve around the Earth.
b. We see the phases of the 
moon because of sunlight 
reflecting off the moon as 
the moon revolves around the 
Earth.

7. III. Moon Stats
a. Distance to earth- average about 240,000 
miles away
(but is moving further away from earth!)
About 4cm higher each year in orbit)
b.  Age- About 4.6 billion years
c. Revolution Period around earth- about 
27 days and it takes about 27.5 days for 
one rotation (one day on the moon!)
d. Temperature 2600 F lunar day to -2800F lunar night
e.  Atmosphere- very little
f. Gravity- 1/6 of Earth’s.
g. Magnetic field- very little

10. IV. Eclipses
a. Solar- when the Moon passes between the Sun and the Earth. (during New Moon) A shadow, or penumbra is cast on the Earth making it appear dark.
Next TOTAL SOLAR ECLIPSE that will be visible in the Unites States is April 8, 2024.
b. Lunar- when the Earth passes between the sun and full moon casting Earth's shadow on the moon.
The next lunar eclipse in North America is May 26, 2021!

11. Why We Have Eclipses:
The moon does not revolve in a flat plane around 
the Earth; but with a slight incline at about 5.9⁰

17. V. Tides a. Tides are the periodic rise and fall of the ocean waters.
b. They are caused by the gravitational pulls of the Moon and Sun, as well as the rotation of the Earth.
c. There are normally 2 high and 2 low tides a day, about every 6.25 hours apart.
d. Spring Tides- high tide is really high, low tide is really low! NOTHING to do with the season of spring!
e. Neap Tides—tides are not as extreme

24. How Tides Affect Ocean Life
*Tides affect marine life by creating different niches where certain organisms can live.
*For example, because of the waves and exposure to air, only certain animals can live where tides go in and out. Tidal currents also bring nutrients to certain areas, encouraging animals to live there
