Solar Eclipses
The Moon moves between the Earth and the Sun and blocks the sunlight from hitting a small portion of the Earth’s surface. Solar eclipses occur at the New Moon phase.
Lunar Eclipses
The Earth blocks sunlight from hitting the Moon’s surface. Lunar eclipses occur at the Full Moon phase.
Draw the moon phase (on the paper)
New moon
All black
Draw the moon phase (on the paper)
Waxing cresent
Cresent on the right side of the moon
Draw the moon phase (on the paper)
First quarter
Half the moon is lit. right side is lit
Draw the moon phase (on the paper)
Waxing Gibbous
smaller, lummitated circle in the moon. Left side of the moon is not lumminated and in a cesent shape and the rest is lumminated.
Draw the moon phase (on the paper)
Full moon
Fully lumminated
Draw the moon phase (on the paper)
Waning Gibbous
Right side on the moon is not lumminated and in a cresent shape while the rest is lumminated
Draw the moon phase (on the paper)
Last quarter
Half of the moon is lit. left side is lit
Draw the moon phase (on the paper)
Waning crescent
Left side of the moon is in a cresecnt shape and the rest is not lumminated
How long does it take for the moon to complete one revlution around the earth
27.3 days
How long does it take the moon to complete a full cycle of itt phases
29.5
Why does it take 2 additional day for the moon to complete its phases
As the moon moves around the earth, the earth moves around the sun.
How long does it take to complete a cycle of the moons phases
1 month
Why does the same side of the moon always face the earth
the revolution and rotation are the same
Draw the pases of the moon in order
Answers on the paper
The moon revolves around the earth once every _____ days
27.3
The moon rotates on its axis once every _____ days
27.3
Waxing means that the illuminated portion gets _____- every night
Bigger
Waning means that the illuminated portion gets _____- every night
Smaller
When does a luner eclipse happen
When the earth passes between the Sun and Moon causing the moon to be blocked out by the shadow of the earth.
Luner eclipses only happen at what phase
Full moon phase
When does a solar eclipse happen
When the moon passes directly between the sun and earth causing the sun to be blocked
A solar eclipse only happens during what phase
New moon phase
Why dont eclipses happen once a month
Because the moons obit is slightly tilted
Define Penumbra
Area of partial eclipse
Define Umbra
Area of total eclipse
Why do tides occur
Because the gravitational pull of the moon and sun
How many high and low tides each day
2 high and low each day
Spring tides occur during what moon phase
New and full moon
When do spring tides occur
When the earth sun and moon are lined up causing higher then normal tides
When do Neap tides occur
When the moon acts on its own causing less severe high tides.
During what moon phase do Neap tides occur
First and last quarter
