Transcript of The Boob

Why is the moon not
a planet?
The Moon
What is the moon?
What is a satellite?
How was the moon
Parts of the moon
What is a lunar eclipse?
How are the moon and earth's
tides related?
The moon is 1/91 the Earths mass. The moon is in a synchronous rotation with Earth
The moon consists of roughly 300,000 1km craters. The crust is estimated to be 50km thick.
There are approximately 3,000 man
made satellites orbiting around
the earth
Gravitational coupling between the moon and the bulge nearest the moon acts as a torque on the Earth's rotation, draining angular momentum and rotational kinetic energy from the Earths spin. Tide=the rise and fall of Sea levels caused by the combined effects of the gravitational forces exerted by the moon and the sun and the rotation of the Earth. Tide happens every 12 hours.

Moons are not planets for, they orbit planets. They are natural satellites which are held by a planets gravity.
As well, not all moons are the same. Some moons have volcanoes, others have atmospheres and others may even have water like our earth. But still, they are considered only moons for they also orbit planets.
Besides Earth, 5 other planets have moons in our solar system. Jupiter has at least 63 moons, Neptune has 8 and Uranus has 21.
Since the moon was created about 4.527 billion years before our time, we are still today un-sure on how exactly the moon was formed. The accepted theory was that an object, roughly the size of Mars is thought to have collided with the Earth when the earth was still forming (which is why we don't see much evidence of the impact here today).
The impact was so large, that material from the Earth's outer layers were sent hurtling into space. The material couldn't get far enough to escape Earth's gravity and it was kept
close by.

A satellite is an object that moves around a larger object. Earth is a satellite because it moves around the sun.
The moon is a satellite because
it moves around Earth. Earth
and the moon are called
"natural" satellites.
Before satellites, TV signals didn't go very far. TV signals only travel in straight lines. So they
would go off into
space instead of following
Earth's curve. Sometimes
they would be blocked
by mountains or
tall buildings.
Satellites fly high in the sky, so they can see large areas of Earth at one time. Satellites also have a clear view of space. That's because they fly above Earth's clouds and air.
Moon= the only natural satellite of Earth
Satellite= an object but into orbit by humans
Natural Satellite= a natural object that orbits another larger object.
Tide=rise and fall of Earths sea levels
Lunar Eclipse= an overshadowing of the moon that occurs when Earth lies directly between the moon and the sun during a full moon phase.
The moon is a differentiated body:
it has a geochemically distinct crust,
mantle and core. The structure of
the moon consists of the crust,
lunar maria, lunar terrae, craters,
mantle and the 3 levels of
the core.
Lunar Maria
Lunar Terrae
The moons largest crater is the largest crater in the solar system at 13km.
13 km
A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra or shadow.
This can occur only when the
Sun, Earth, and Moon are aligned exactly, or very.
Earth is the only planet with a single satellite revolving around it. The moon is the brightest
body in the solar system to us.
The moon has no atmosphere.
Moon: celestial bodies
that orbit a planet. Earth
has one moon. There
are 150 moons
in the solar
The moon reflects light. The
moon is the only natural satellite of the
Earth. The moon is the 5th largest satellite in the Solar System.
Alright, So where do we begin?
Still hot, the matter began to orbit about the Earth, colliding with itself and eventually coming together like putty. After billions of years, this large mass came to exist in the form that we are all familiar with today...
The Moon...
Also unlike solar eclipses, lunar eclipses are safe to view without any eye protection or special precautions, as they are no brighter
than the full moon itself
The type and length of an eclipse depend upon the Moon's location relative to its orbital nodes. Unlike a solar eclipse, which can only be viewed from a certain relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of the Earth. A lunar eclipse lasts for a few hours, whereas a total solar eclipse lasts for only a few minutes at any given place, due to the smaller size of the moon's shadow.
The tides of the Earth are mostly generated by the gradient in intensity of the Moon's gravitational pull from one side of the Earth to the other. Forms two bulges on the Earth. The Earth spins 27 times faster than the moon moves, rotating around the Earth once a day as it spins on its axis.
Good luck to you in jeopardy...
