Quick Facts

• Size -- 2,140 miles in diameter, about 27the
  size of earth
• Comprised of -- mostly volcanic rock, a powdery
  dust
• Distance from Earth -- 240,250 miles from Earth

4
Quick Facts (cont.)

• Gravity moons gravity is 17 of the Earth's
  gravity (a 100 pound person would weigh only 17
  pounds on the Moon)
• Atmospheric conditions no atmosphere

5
Missions to the Moon

• Lunar exploration began 1959
• U.S. missions such as Ranger, Surveyor and Lunar
  Orbiter photographed the lunar surface preparing
  for astronauts to land there
• On July 20, 1969, Neil Armstrong walked on the
  surface of the moon during the Apollo 11

6
Missions to the Moon (cont.)

• Missions Apollo 12-17 focused on collection of
  rock samples for analysis
• 1994 a NASA spacecraft discovered possible water
  (ice) on the moon

7
Theories of Origin

• Impact Theory Earth collided with a large
  object (the size of Mars or larger) sending
  pieces of the earth into space, which eventually
  became the moon (most widely accepted)
• Coaccretion theory the Moon formed in Earth's
  orbit along with all the other planets in the
  Solar System

8
Theories of Origin (cont.)

• Fission theory In early days of the solar
  system, the earth was spinning so fast that a
  piece of the earth flew off and remained in the
  earths orbit
• Capture theory the moon was formed elsewhere in
  the solar system and was captured by the earth,
  perhaps by gravity
• What do you think??

Lunar PhasesWhy does the moon change shape in
the sky?We do not see all of the daytime side of
the moon, because the moon revolves around the
earth.

• Moon Phases demonstration from the Internet

10
Identify Phases

• New Moon the new moon is not visible because the
  shadow of the moon faces the earth

11
Phases cont..

• Waxing Crescent shaped like a thumbnail

12
Phases cont..

• 1st Quarter (first moon) half moon

13
Phases cont..

• Waxing Gibbous almost full

14
Phases cont..

• Full Moon the entire side of the moon facing the
  earth is illuminated

15
Phases cont..

• Waning Gibbous is getting smaller

16
Phases cont..

• 3rd Quarter (Last moon) half moon

17
Phases cont..

• Waning Crescent looks like a thumbnail

18
ECLIPSE!

• Solar Eclipse the moon pass directly between the
  earth and the sun

19
ECLIPSE!

• Lunar Eclipse the earth passes directly between
  the moon and the sun

20
Tides, Tides, Tides

• The oceans swell due to the gravitational pull of
  the moon on the earth

21
Tides, Tides, Tides

• Sometimes the difference in high and low tide is
  very dramatic!
