Phases, Eclipses, and Tides

When are tides highest?
a.during the moon's first quarter phase
b.when the sun, Earth, and the moon are nearly in a line
c.during the moon's third quarter phase
d.when the moon is at a right angle to the sun

B. when the sun, Earth, and the moon are nearly in a line

Tides are caused by the force of gravity from the sun and moon acting on Earth.
TRUE OR FALSE

TRUE

A tide with the least distance between low and high tides is called a neap tide.
TRUE OR FALSE

TRUE

The darkest part of the moon's shadow is called the penumbra.
TRUE OR FALSE

FALSE

During a total lunar eclipse, the moon is in Earth's
a.corona.
b.penumbra.
c.umbra.
d.orbit.

C. umbra

For a solar eclipse to occur,
a.the sun must be directly between Earth and the moon.
b.the moon must be directly between Earth and the sun.
c.the moon must be directly behind Earth.
d.Earth must be directly between the sun and the moon.

B. the moon must be directly between Earth and the sun.

Based upon what you have learned about the position of the earth, sun, and moon during a lunar eclipse, during which phase of the moon can a lunar eclipse occur?
a.new moon
b.first quarter
c.waxing gibbous
d.full moon

D. full moon

A lunar eclipse can occur during a full moon.
TRUE OR FALSE

TRUE

The phase of the moon you see depends on
a.where you are on Earth's surface.
b.how much of the sunlit side of the moon faces Earth.
c.how much of the moon's surface is lit by the sun.
d.whether or not an eclipse is occurring.

B. how much of the sunlit side of the moon faces Earth

A total solar eclipse is visible from
a.all over Earth.
b.only within the moon's umbra.
c.only within the moon's penumbra.
d.only the dark side of Earth.

B. only within the moons umbra

Phases

One of the different apparent shapes of the moon as seen from Earth.

Eclipse

The partial or total blocking of one object in space by another.

Solar eclipse

The blocking of sunlight to Earth that occurs when the moon is directly between the sun and Earth.

umbra

The darkest part of a shadow

Penumbra

The part of the shadow surrounding the darkest part

lunar eclipse

The blocking of sunlight to the moon that occurs when Earth is directly between the sun and the moon

Tide

The periodic rise and fall of the water level in the ocean and other large bodies of water

Spring Tide

A tide with the greatest difference between high and low tide that occurs when the sun and moon are aligned with Earth and the new moon and full moon.

Neap Tide

A tide with the least difference between low and high tide that occurs when the sun and moon pull at right angles to each other at the first and third quarters of the moon.

Because the moon rotates once for each revolution around Earth,
a.you see some phases more than others.
b.a different side of the moon faces Earth each day.
c.you never see the far side of the moon from Earth.
d.the far side of the moon is visible only during the full moon phase.

C. you never see the far side of the moon from Earth

The phases of the moon depend on how much of the lighted side of the moon can be seen from Earth.
