Moon Basics
This is the source of the moon's light.
The sun
The term for the Moon when the illuminated portion is "growing" or getting larger.
Waxing
True or False: The Moon's phases are caused by clouds covering it.
False
This force is the main cause of Earth's tides.
The gravitational pull of the moon and the sun.
This type of tide features the most extreme difference between high and low tide.
True or False: Half of the Moon is always lit by the Sun.
True
The term for the Moon when the illuminated portion is "shrinking" or getting smaller.
Waning
A common misconception is that the phases are caused by this object's shadow.
The Earth's shadow.
The number of high tides and low tides most shorelines experience each day.
Two of each.
Spring tides occur during these two Moon phases.
The New Moon and the full Moon.
The approximate time it takes the Moon to revolve around the Earth, about 29.5 days. This is about _______.
one month (or the lunar cycle)
This phase occurs when the Moon is between the Earth and the Sun, making it invisible from Earth.
New Moon
The actual cause of the Moon's phases.
The moon revolving around the Earth (and us seeing the lit side from different angles).
Besides gravity, these local factors can affect the height of tides.
The shape of the coastline and the depth of the water?
This type of tide features the least extreme difference between high and low tide.
A Neap Tide
This term describes sunlight reflecting off the Earth to faintly illuminate the dark part of the Moon.
earthshine
This phase occurs when the Earth is between the Sun and Moon, and we see the entire lit side.
Full Moon
These events happen when a shadow is cast on either the Earth or the Moon.
Eclipses
If the Moon were farther away, its gravity would be weaker, causing tides to be this.
Weaker or less extreme.
Neap tides occur during these two Moon phases.
First and Third Quarter
Does everyone see the same side of the moon? Yes or No
Yes
The correct order of the four main phases, starting with a New Moon.
New Moon -- First Quarter -- Full Moon -- Last Quarter
A person in China and a person in the United States see different phases of the Moon on the same night. Both are in the northern hemisphere.
False.
Both Moon phases and tides depend on the relative positions of these three celestial bodies.
The Sun, Earth and Moon.
Neap tides are less extreme because the Sun and Moon's gravitational pulls are working in this way.
Against each other (or at a right angle).
