Which diagrams above best illustrate the positions of the Earth, Moon, and Sun during a neap tide?
New moon
During which moon phase can a solar eclipse occur?
Spring tides
tides have the largest difference in water level between high and low tides
Neap tides
tides have the smallest difference in water level between high and low tides

50%--however we can't always see it.
What percentage of the Moon is always reflecting sunlight in space?
2 high tides and two low tides (usually)
Most locations experience this many high and low tides each day.
New and Full Moon produces these tides.
During which two moon phases of the moon do spring tides occur?
Light from the Sun is blocked.
From Earth what is being blocked during a total solar eclipse?
The sunlight reflecting from the Moon to the Earth.
From Earth what is being blocked during a total lunar eclipse?
Moon's orbit is tilted, so we don't see these every month.
Why don't we see solar and lunar eclipses every month?
Becoming larger, growing.
What does waxing mean?
Becoming smaller, diminishing.
What does waning mean?
1st Quarter and 3rd or Last Quarter produce these tides.
During which two moon phases do neap tides occur?
Per month, two of each type are produced.
Spring tides and neap tides occur how many times each, per month?
Spring tides
Which tides occur when the sun, moon, and Earth are aligned?
You have to wait about 6 hours after one to see the other.
About how long would you have to wait to see a high tide after a low tide?
Solar eclipse
Name the eclipse type.
Lunar eclipse
Name the eclipse type.
The Earth
During a solar eclipse, what does the Moon cast a shadow on?
The Moon
During a lunar eclipse, what is in Earth's shadow?
Moon's gravity
What has the greatest influence on Earth's tides?
About a month
You saw a full moon on June 11, how long will you have to wait to see a full moon again?
12 hours
About how long would you have to wait to see another high tide once one has occurred?
Low tide
If you were in between Earth's tidal bulges, what tide would you experience?
High tide
If you were in the ocean on the opposite side of Earth from the moon, what tide would you experience?
High tide
If you were in Earth's tidal bulge, what tide would you experience?
Penumbra (less dark shadow)
Which shadow would you have to be standing in to see a partial solar eclipse or partial lunar eclipse?
Umbra (darkest shadow)
Which shadow would you have to be standing in to see a total solar eclipse?
Tide, definition.
The term used to describe the rise and fall of ocean water levels.
Neap Tide, definition
What tides occur when the Sun, Earth, and Moon are at right angles to each other?
Full moon
