Warm Up, March 26, 2013

Fact: On earth we only ever see the same side of the moon. In other words, it is phase locked.

Question for you: Can/does the moon rotate? Or does it just revolve around earth? Explain your thinking.


It does rotate

It does rotate!

  • The moon’s rotation is the same length as its revolution around earth.

  • Try It!

  • Pick a partner. One of you act as the earth and one act as the moon.

12 4 the moon

12.4 The Moon

  • Galileo invented a telescope like the one below and was the first person to view the moon through it.

  • He was able to see details of the moon no one had seen before.


Earth s moon facts

Earth’s Moon Facts

  • Size: 3,476 km in diameter (about the same distance as going from LA to NY)

  • No atmosphere

  • No iron core, so no magnetic fields

  • Temperature range: -180°F to 300°F

  • No liquid water

  • Phase Locked: we always see the same side of the moon from earth

  • About 4.6 billion earth-years old or 4 600 000 000 years.

  • Largest moon relative to its planet in our solar system

  • One-sixth of earth’s gravity


The moon s surface

The Moon’s Surface

  • Maria – Latin for “seas”, these are the dark lowland areas, ancient people thought these were oceans.

  • Highlands – The lighter regions of the moon are the highlands


Craters

Craters

  • The moon has no atmosphere, or layer of gases around it to protect it from meteoroids.

  • Meteoroids are simply chunks of rock that are moving in space. (Because of Newton’s 1st Law, they keep moving until they hit something – like the moon)

  • Most craters are found in the highlands and not in maria.


Shooting stars on earth

Shooting Stars on Earth

  • When small meteoroids are on a collision course with earth, they usually burn up in our atmosphere.

  • We call them “shooting stars” although they are not “stars” at all.

  • It the meteoroid reaches earth’s surface, we call it a meteorite.
