2. HYPOTHESIS of how the moon was formed
The condensation hypothesis suggest the moon was formed in a cloud
of gas and debris just like the planets
The capture hypothesis suggests the moon was an asteroid that was
captured by the earths gravitational mass
The fission hypothesis states the moon broke off as a chunk of the
earth while the planet was spinning fiercely
The large impact hypothesis states that a mass the size of mars
crashed into earth nearly destroying the planet and sending a
massive cloud of debris into orbit. this debris over time came
together to form what is now known as our moon.
3. The beginning of the moon
When the moon was created 3.8-4.5 billion years ago, it was
pummeled with asteroids and the low areas filled with oozing molten
lava
Over a period of 750 million years the molten lava cooled to form
areas that are black like ash known as the maria.
4. Craters and Maria on the moon
The moon is littered with craters and large low lying flat
lands.
5. The Highlands
the cratered areas are called the highlands and the dark low areas
are called the maria.
6. Geology of the moon
The dark gray areas of the moon that we see from earth are known as
the lunar lowlands.
The lighter colored mountains are known as the lunar
highlands.
The moon looks bright against the stars in the night sky, but it
only reflects 6 percent of the light that hits it.
The craters on the moon were created by impacts. Most were created
when the solar system was young.
The hilly regions of the moon are covered with a rock called
anorthosite. This rock is a light colored rock which is made up of
calcium and aluminum.
7. The Motions of the Moon
The moon moves eastward in the sky, toward the background
stars.
Each night if you were to watch the moon, its about 13 degrees east
from the spot it was the night before.
The moon takes about one month to completely orbit around the
earth.
8. Moon Phases
The moon always keeps the same side facing the earth, and you never
see the far side.
Sun illuminating on different parts of the side of the moon
produces the different phases of the moon.
The orbital period of the moon around the earth is not the same as
the length of a moon phase cycle.
The phases of the moon are New Moon, Waxing Crescent, First
Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter
Moon, and Waning Crescent.

11. Your Weight on the moon
The moon is 1/4 the size of Earth, so the moon's gravity is much
less than the earth's gravity, 83.3% less.
If you weigh 150lbs on Earth you would only weigh 24.9lbs on the
moon. Or 1/6th of your weight of that on the Earth.
12. Gravity field of the moon
The gravitational acceleration on the surface of the moon is 1.63
m/s2 or about 16.7% that on Earth's surface.
The major characteristic of the Moon's gravitational field is the
presence of mascons, which are large positive gravity anomalies
associated with some of the giant impact basins.

15. Life On The Moon
No life currently exists on the moon that we know of, and no life
used to exist that we know of
Water is the basis of life that we know and the moon lacks the
abundant amount needed to support life
In 2009 water on the moon was found in such small increments that
the earths driest deserts have more water
In 2010 an estimated 600 million tones of frozen layers meters
thick of ice were found in the north pole of the moon
