Title: Earth and Phases of the Moon


1
EARTH, MOON SUN
  • Write Everything in BLUE

2
Earths Rotation
  • The Earths axis is an imaginary line that runs
    through the center of the Earth
  • The Earth rotates on its axis making a complete
    circle in 24 hours
  • Rotation is what causes day and night
  • Earths tilted axis is what causes the seasons

3
Earths Revolution
  • Revolution is how the Earth revolves around the
    sun
  • One complete revolution takes 1 year
  • The tilt of the Earths axis means that for part
    of the year, the Northern Hemisphere is pointed
    towards the sun and the other part of the year it
    is tilted away from the sun

4
Solstice
  • Solstice occurs when the sun is directly overhead
    at noon at 23.5 N or 23.5 S latitude
  • June 21st the sun is overhead in the Northern
    Hemisphere so the daylight hours are the longest
  • December 21st - the sun rays are indirectly
    hitting the Northern Hemisphere so the daylight
    hours are the shortest

Winter Solstice
5
Equinox
  • Equinox occurs when the daylight hours and night
    hours are exactly the same
  • The sun is directly overhead at noon at the
    equator
  • Vernal equinox occurs on March 21 and marks the
    beginning of spring
  • Autumnal equinox occurs on September 23 and marks
    the beginning of fall

6
Phases of the Moon
  • The positions of the moon, Earth, and the sun
    causes the phases of the moon, tides, eclipses.
  • The moon revolves around the Earth in about 27
    days
  • We always see only the near side of the moon
  • The moon reflects the light of the sun
  • We see different shapes of the moon due to the
    positions of the moon, Sun Earth

7
Serpent Mound, Ohio
  • Each curve of the snake represents a direct
    alignment of the sunset or sunrise on the day of
    a solstice or equinox

8
Phases of the Moon
Draw Each of the Moons on the Following Slides!
9
Moon Phases
  • Full Moon we see the whole lighted area of the
    moon

10
Moon Phases
  • Waning Gibbous the moon will seem to get a
    little smaller

11
Moon Phases
  • Third or Last Quarter You can see half of the
    moons lighted side (the left side)

12
Moon Phases
  • Waning Crescent You see a very small portion of
    the moon resembling a crescent

13
Moon Phases
  • New Moon the sun lights the side of the moon
    that faces away from the Earth so we dont see
    anything

14
Moon Phases
  • Waxing Crescent You see more of the moon -the
    right side of the crescent

15
Moon Phases
  • First Quarter You see the right half of the
    lighted moon

16
Moon Phases
  • Waxing Gibbous the amount of the right side of
    the moon that we see continues to grow

18
Eclipses
  • An eclipse occurs when an object in space comes
    between the sun and another object

19
Solar Eclipse
  • A solar eclipse occurs when the new moon passes
    between the sun and Earth
  • umbra the darkest part of the moons shadow
    which results in a total solar eclipse
  • penumbra the larger part of the moons shadow
    which results in a partial eclipse

20
Lunar Eclipse
  • A lunar eclipse occurs when the Earth comes
    between a full moon and the sun

21
The Moon
  • The moon is ¼ the size of Earth
  • In 1609 Galileo made a telescope and was the
    first person to view a close-up of the moon
  • The dark spots on the moon are low dry areas
  • Craters on the moon are the result of meteor
    impacts

22
Mission to Space
  • The USSR Sputnik was the first satellite to
    orbit the Earth in 1957
  • Yuri Gagarin was the first person to orbit the
    Earth
  • In July 1969, Apollo 11 carried the first men to
    the moon
  • Neil Armstrong and Buzz Aldrin were the first men
    to step on the moon
