Lunar Phases
This phase occurs when the Moon is directly between the Earth and the Sun, appearing dark from our perspective.
New Moon
When the Sun, Moon, and Earth align in a straight line, they create these exceptionally high and low tides.
Hint: It's named after a season
Spring Tides
This is the primary invisible force labeled in the diagram that "pulls" the ocean water.
Gravity
As the Moon moves from New to Full, we use this 6-letter word to describe the visible portion "growing."
W----g
Waxing
This is the name for the weaker, "moderate" tides that occur during the quarter moon phases.
N--- tides.
Neap Tides
While the Sun is much larger, this celestial body is the "boss" of the tides because it is much closer to Earth.
Moon
According to the diagram's labels, this phase is found at the bottom, directly opposite the "waning quarter."
Waxing Quarter
Looking at the Earth in the center of the diagram, this is the total number of high tide "bulges" shown at any one time.
Two
During a New Moon, the gravitational pull comes from the Moon and this other giant body.
Sun
It takes approximately this many days for the Moon to complete one full cycle through all its phases.
29.5 days (29 or 30 days acceptable)
This term describes the vertical difference in height between a high tide and the succeeding low tide.
Tidal R---e
Tidal Range
At a Neap Tide, the Sun and Moon are positioned at this specific angle relative to the Earth.
Right angle (90 degree angle acceptable)
Because of "Tidal Locking," the Earthlings only ever see this percentage of the Moon's surface.
50%
Seven days after a Spring Tide, the Moon will have moved into a position to cause this other type of tide.
Neap Tide
The "bulge" on the side of Earth away from the Moon is caused by this property of matter that resists changes in motion.
Inertia
