Unit 2 Chap 4 - Test - Moon and Lunar Phases

Front

What are the phases of the Moon?

Back

The phases of the Moon are the different appearances of the Moon as seen from Earth, which include New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, and Waning Crescent.

Front

How long does it take for the Moon to orbit the Earth?

Back

It takes approximately 27 days for the Moon to complete one orbit around the Earth.

Front

What is a New Moon?

Back

A New Moon is a phase of the Moon when it is completely dark and not visible from Earth.

Front

Why do we see different phases of the Moon?

Back

We see different phases of the Moon because of the changing positions of the Moon, Earth, and Sun, which affect how much of the Moon's surface is illuminated by the Sun.

Front

What is the Full Moon phase?

Back

The Full Moon phase occurs when the entire face of the Moon is illuminated by the Sun, making it fully visible from Earth.

Front

How often does a full cycle of lunar phases occur?

Back

A full cycle of lunar phases occurs approximately once a month.

Front

What is the significance of the Moon's rotational period?

Back

The Moon's rotational period is significant because it is the same as its orbital period around Earth, which is why we always see the same side of the Moon.

Front

What is a Waxing Crescent Moon?

Back

A Waxing Crescent Moon is the phase that occurs after the New Moon, where a small sliver of the Moon becomes visible and gradually increases in size.

Front

What is a Waning Gibbous Moon?

Back

A Waning Gibbous Moon is the phase that occurs after a Full Moon, where the visible portion of the Moon decreases.

Front

What causes the Moon to appear to change shape?

Back

The Moon appears to change shape due to the varying angles of sunlight hitting its surface as it orbits Earth.
