Lunar Eclipse
|
occurs when Earth is directly between the moon and the sun
Earth's shadow is blocking the moon
Can only occur during a full moon
|
|
Penumbra
|
The larger part of the moons shadow that is less dark than the umbra.
|
|
phases
|
the different shapes of the moon we see from Earth
|
|
Partial Lunar Eclipse
|
Occurs when the moon passes partly into the umbra of Earth's shadow
|
|
orbit
|
The Moon in the new moon phase is between the Earth and the Sun in its ______.
|
|
positions
|
phases are caused by changes in the relative _________ of the moon, Earth and the sun
|
|
sunlight
|
half the moon is always in ____________.
|
|
Lunar
|
the New Moon Marks the beginning of the ______ Cycle
|
|
Waning Gibbous
|
We see almost the entire left side of the lit Moon
|
|
Spring tide
|
Occurs twice a month when the Earth, moon and sun are positioned in a straight line
the sun's gravity adds to the moons pull causing the greatest difference between low and high tide
|
|
Total Solar Eclipse
|
Occurs when the sun is completely blocked by the moon
|
|
total
|
Only the people located in the umbra will see the ________solar eclipse.
|
|
First Quarter
|
We see the right half of the lit Moon
The Moon and Earth are now "side by side" in their orbits
|
|
high tide
|
gravity of the moon pulls on Earth's waters creating a bulge of water (called a tidal bulge) on the side of Earth closest to the moon
A tidal bulge also forms on the exact opposite side of Earth
When this occurs, both points on Earth experience it
|
|
How do tides occur?
|
From the differences in how much the moon's gravity pulls on different parts of Earth
|
|
Tides
|
The rise and fall of water ( approx. 12.5 hours)
|
|
partial
|
People located in the penumbra see only a _______ solar eclipse
|
|
Total Lunar Eclipse
|
occurs when the moon is completely in the umbra of Earth's shadow
|
|
neap tide
|
the moon and sun are at right angles and the sun's gravity works against the moons pull of Earth's waters causing the least difference between low and high tide
|
|
Waxing Gibbous
|
We see almost the entire right side of the lit Moon
|
|
Umbra
|
darkest part of the moon's shadow (cone-shaped)
|
|
Lunar eclipse order
|
Sun - Earth - Moon
|
|
two
|
There are __ high and ____ low tides in a 24 hour period
|
|
unsafe
|
This eclipse is ________ to look at because part of the sun is still visible
|
|
Earth
|
the phase we see depends on how much of the sunlit side of the moon faces __________
|
|
Partial Solar Eclipse
|
Occurs when part of the sun is still visible from Earth
|
|
New Moon
|
We can see NO portion of the Moon's surface that is lit.
We see only the dark side of the Moon.
|
|
Full Moon
|
We see the entire half of the Moon surface that is lit
The Moon is positioned behind the Earth and Sun
|
|
solar eclipse order
|
Sun - Moon - Earth
|
|
Last Quarter
|
We see the left half of the Moon lit
The Moon and Earth are now "side by side" in their orbits
|
|
Waxing Crescent
|
We see on the right side, a small sliver of the lit Moon
|
