Third Quarter

First Quarter

1/2 of the side of the Moon Facing Earth is Lighted.

What is Phases?

A Different Shapes of the Moon you see from Earth are called Phases.

When the Moon's Shadow Hits Earth or Earth's Shadow Hits the Moon, What Occurs?

A Eclipse Occurs.

What is a Spring Tide?

A Tide with the Greatest Different Between Consecutive Low and High Tides.

What is a Neap Tide?

A Tide with the least Difference Between Consecutive Low and High Tides.

Full Moon

All of the Moon Facing Earth is Lighted.

Waning Gibbous Moon

As the Moon continues the second half of its revolution, the amount of lighted area that's seen decreases. In this phase, on the left side of the Moon is seen, but more than the Third Quarter Moon.

Waxing Crescent Moon

As the Moon revolves around the Earth, a silver of light on the right side of the Moon is seen, forming a crescent. As the amount of illuminated area increases, this is termed "Waxing".

The study of the Moon, Stars, and other objects in Space is called ________.

Astronomy

Each 24-hours Cycle of Day and Night is called a(n) ________.

Day

Why does Earth have Season?

Earth have season because its axis is tilted as it revolve around the sun.

What is the Arrangement of Earth, Moon, and Sun during a Lunar Eclipse?

Earth is Directly Between the Moon and Sun.

What cause Day and Night?

Earth rotation causes day and night.

Why is an extra day added to February every four years?

Earths orbit around the sun takes 365 and 1/4 days.

Each of the two days of the year when neither Hemisphere is Tilted Toward or Away from the sun is called a(n) ________.

Equinox

(True Or False) Earth is closest to the sun when it is summer in the Northern Hemisphere.

False

(True Or False) In December, the shortest Daytime is in the Southern Hemisphere.

False

(True Or False) The Autumnal Equinox Falls on September 22 to mark the Beginning of Fall in both Hemisphere.

False

(True or False) People in Earth's Umbra see a Total Lunar Eclipse.

False

(True or False) People in the Penumbra see a Total Solar Eclipse.

False

(True or False) People in the Umbra see only a Partial Solar Eclipse.

False

(True or False) The Hemisphere that is tilted away from the sun has more daylight that the other Hemispheres.

False

(True or False) The Moon Rotates slowly on its Axis once every 27.3 Days.

False

(True or False) The Moon revolves around the Earth once a Year.

False

A Low Tide Occurs at the Point on Earth Farthest from the Moon.

False

Every Location on Earth has Two High Tides per Month.

False

What Force Pulls the Moon and Earth Toward each other?

Gravity

What does the Phase of the Moon you see Depends on?

It Depends on how much of the Sunlit Side of the Moon Faces Earth.

How often does the Moon goes through an Entire Set of Phases?

It goes through a Whole set of Planets each time it Revolves around Earth about every 29.3 Days.

Why is it warmer near the Equator than near the Poles?

It is warmer because sunlight lit Earth surface more directly and is spread out at the equator.

What Percentage of the Dark side of the Moon do you see during the First and Third Quarter?

It's About a Half.

Waxing Gibbous Moon

More than a quarter of the Moon is illuminated, but less than a Full Moon. "Waxing" means increasing or growing larger. Gibbous means more than half, but less than full, or bulging.

The Darkest Part of the Moon's Shadow is called the _________.

New Moon.

The Largest part of the Shadow, Less Dark than the Umbra, is called a __________.

Penumbra.

What are the Two Types of Eclipse?

Solar, and Lunar Eclipses.

Each of the two day of the year when the Noon Sun is farthest North or South of the equator is called a(n) ________.

Solstice

Last (Third) Quarter Moon

Sometimes this is referred to as the Third Quarter Moon. After about three weeks from the beginning of the cycle, the Moon is about three quarters through its revolution, and the left hand of the circle is illuminated.

Calender

System of Organizing time that Defines the Beginning, Length, and Divisions of a Year.

What causes a Solar Eclipse?

The Moon Passes Directly Between Earth and the Sun, Blocking Sunlight from Reaching Earth.

New Moon

The Moon appears dark, because the lighted side is away from the Earth. The Moon is aligned with the Earth and Sun.

Waning Crescent Moon

The Moon is close to completing its revolution, and only a silver of light is visible on the left side of the Moon. There will soon be a New Moon, and the cycle will start over again.

Is the Near Side (Facing Earth) Always the Dark Side?

The Near Side is not always the Dark Side. The Near Side is the Dark Side during a New Moon. The Far Side is the Dark Side during a Full Moon.

Equinox

The Noon Sun is directly Overhead at the Equator at this Time.

Solstice

The Sun is Farthest North or South of the Equator at this Time.

What is Axis?

The imaginary line that passes through Earth's center and the North and South poles.

What is Revolution?

The movement of one object around object.

What is Orbit?

The path of an object as it revolves around another object in space.

New Moon

The side of the moon facing Earth is Dark.

What is Rotation?

The spinning motion of Earth on its axis.

Why do Tides Occur?

They Occur mainly because of difference in how much the Moon's Gravity Pulls on Different parts of the Earth.

What causes the Phases of the Moon, Eclipses, and Tides?

They are all Caused by the Relative Positions of the Moon.

First Quarter Moon

This image occurs when the Moon is about a quarter of the way in its revolution around the Earth. Although it looks like half of the Moon is illuminated, we see half of the half that is facing Earth. This is called the first quarter phase.

The Rise and Fall of Ocean Water are called ________.

Tides

(True Or False) An Equinox Occurs on the same Days at the same Time in both Hemisphere.

True

(True Or False) In June, there are fewer hours of Daylight and less direct Sunlight in the Southern Hemisphere.

True

(True Or False) When it is summer in the Northern Hemisphere it is winter in the Southern Hemisphere.

True

(True Or False) When the Northern Hemisphere has summer, the Southern Hemisphere is Tilted Away from the sun.

True

(True or False) A "Day" and a "Year" on the Moon are the same Length.

True

(True or False) A Lunar Eclipse Always Occurs at a Full Moon.

True

(True or False) A Partial Lunar Eclipse Occurs when the Moon Passes Partly into the Umbra of Earth's Shadow.

True

(True or False) During a Lunar Eclipse, Earth Blocks Sunlight from Reaching the Moon.

True

(True or False) During a Total Solar Eclipse, part of the Sun Remains Visible.

True

(True or False) During a Total Solar Eclipse, the Sky Grows Dark.

True

(True or False) The Point on Earth that is Closest to the Moon has a High Tides.

True

(True or False) The same Side of the Moon always Faces Earth.

True

The Point on Earth Farthest from the Moon has a High Tide.

True

Full Moon

When the Moon is halfway through its orbit, the half that faces the Sun is totally illuminated. This occurs two weeks after a New Moon. The Sun, Earth, and Moon are in a line. If they are perfectly aligned, there is a lunar eclipse.
