2.  Regolith is the dry crusty rocky surface that
covers the crust it is composed of lots of
different elements. There are dark areas of the
moon which are basaltic lavas. There is no
atmosphere and there are impact craters. There
are also many mountain ranges on the moon

3.  The thickness of the crust ranges from 60 to
100 km. There have been many additions to the
surface of the crust. The most voluminous
addition to the moon are formations called
mare basalts. These mare basalts were formed
3.9 billion years ago. Most people think of the
crust as the first layer, but actually it is the
second. The rocks on the moon are similar to
rocky surface on earth except they are richer in
Titanium and Aluminum

4.  The rigid mantle : This rocky layer is not hot
enough to flow. This hard shell is about 620
miles (1,000 km) thick. This is the third part of
the moon. The moon gets less compact as it
goes farther towards the core because it also
gets hotter and the flow of elements usually
increases as temperature rises.

5.  This Is The fourth layer of the moon since it is
getting closer to the core, this is the part of the
mantle that has been heated up and is non
rigid. This is the last layer to go until we get to
the first part of the core.

7.  The magnetic field of the moon is not even
close to the enormous magnetic field of earth.
The moon’s magnetic field is actually only one
tenth millionth of earth’s magnetic field. In
fact, if you were to bring a compass on to the
moon the magnetic field would be so weak it
wouldn’t even work. Because there is no
atmosphere on the moon, you wouldn’t need a
compass for if you were skilled, you could find
your way using the stars.

10.  Mercury- 0 moons
 Venus- 0 moons
 Earth- 1 moons
 Mars- 2 moons
 Jupiter-63 moons
 Saturn -62 moons
 Uranus- 27 moons
 Neptune- 13 moons
 Pluto-3 moons

11.  Io is primarily composed of silicate rock
surrounding a molten iron or iron sulfide core.
Most of Io's surface is characterized by extensive
plains coated with sulfur and sulfur dioxide frost.
 Europa and are Io somewhat similar in bulk
composition to the land planets primarily
composed of silicate rock. Unlike
Io, however, Europa has a thin outer layer of ice.
Europa has a layered internal structure perhaps
with a small metallic core.

12.  Ganymede Is fully distinguished, consisting of
an iron sulfide–iron core, silicate mantle and an
outer ice mantle. This moon actually has a
magnetic field.
 Callisto may have a small silicate core and
possibly a subsurface ocean of liquid water at
depths greater than 100 km. The surface of
Callisto is heavily cratered and extremely old.

13.  Mercury Does not have any moons

14.  Venus does not have any moons

15.  Phobos- might contain a substantial reservoir
of ice. Spectral observations indicate that the
surface regolith layer lacks hydration, but ice
below the regolith is not ruled out.
 Deimos- is highly non-spherical with
dimensions of 15 × 12.2 × 10.4 km. Deimos is
composed of rock rich in carbonaceous
material. The regolith is very pou.rous

16.  Titan- Titan is so large it affects the orbit of
other moons. This Is the second largest moon in
the solar system. Its atmosphere is nitrogen
rich, with traces of methane.
 Lapetus- One side of Lapetus is white as snow
as the other side, black as velvet.
 Mimas- Mimas has a giant crater, this I s
because long ago there was a great impact to
the moon nearly blowing it apart.

17.  Phoebe- This moon orbits in the opposite
direction as the other moons. There have been
other moons found to orbit this way.

18.  Naiad- is brokenly shaped and probably has
not been modified by any internal geological
processes after its formation. It is likely that it is
a rubble pile re-made from fragments of
Neptune's original satellites, which were
smashed up by agitations.
 Thalassa- Like Naiad, Thalassa is strangely
shaped and has been smashed.
