1. The Moon has many craters and smooth areas called maria. Its gravity is 1/6 that of Earth, so it cannot retain water or atmosphere. 2. The same side of the Moon always faces Earth because it rotates at the same rate that it revolves around Earth. 3. It is widely accepted that the Moon was formed from debris left over after a large object collided with Earth when it was young. Rocks brought back from the Moon match Earth's composition.

1. Our loyal companion

2. 1. Pock marked with craters and maria
(mar’-ee-a for plural,) or mare (mar’-eyh,)
which are the smooth places.
Gravity 1/6 that of the earth: 9.8/6 =
1.7 m/s2. That is why no water or
atmosphere will stay there.

3. We always see the same side of the
moon because it rotates on its axis at
the same rate it revolves around the
earth.
Try the dime/quarter experiment.

4. 1. Fission: The moon was material
separated from the earth when
the earth was first forming.

5. 2. Capture: The moon was formed
in another part of the solar
system and captured by the
earth’s gravity.

6. Condensation: The moon was
formed near to and simultaneously
with the earth in the early solar
system.

7. None of
them!!

8. Mars size
celestial object
collided with the
Earth. This is well
tested with
evidence.
Rocks from the
moon have
been found on the
Artic continent. They have the same
composition as that of the earth.

9. Solid Iron inner core.
Semi-solid outer core.
Solid mantle.
Crust is thicker on the side facing away
from the earth.

10. maria: singular is mare
mascons: mass
concentrations beneath the
maria.

11. Craters: the pocks and
holes.
Coming out of these
are lines called rays.
Regolith:
The dust.

17. The Moon has quakes:
These are caused by the gravitational pull of
the Earth. Lunar astronauts used
seismographs on their visits to the Moon, and
found that small moonquakes occurred several
kilometres beneath the surface, causing
ruptures and cracks. Scientists think the Moon
has a molten core, just like Earth.

18. The Moon has only been walked on by 12
people; all American males:
The first man to set foot on the Moon in 1969
was Neil Armstrong on the Apollo 11 mission,
while the last man to walk on the Moon in 1972
was Gene Cernan on the Apollo 17 mission.
Since then the Moon has only be visited by
unmanned vehicles.

19. The Moon is the fifth largest natural satellite
in the Solar System:
At 3,475 km in diameter, the Moon is much
smaller than the major moons of Jupiter and
Saturn. Earth is about 80 times the volume
than the Moon, but both are about the same
age. A prevailing theory is that the Moon was
once part of the Earth, and was formed from a
chunk that broke away due to a huge object
colliding with Earth when it was relatively
young.

20. The Moon will be visited by man in the near
future:
NASA plans to return astronauts to the moon to
set up a permanent space station. Mankind
may once again walk on the moon in 2019, if
all goes according to plan.
