Moon Review - Earth Science

Front

What causes the Moon to show phases when viewed from Earth?

Back

The relative positions of the Sun, Earth, and Moon cause the Moon to show different phases as it orbits Earth.

How does the Moon appear to an observer in New York when it is at position A?

Back

The Moon appears as a crescent or gibbous, depending on its position relative to the Earth and Sun.

Front

What arrangement of the Sun, Moon, and Earth results in the highest high tides and lowest low tides?

Back

When the Sun, Moon, and Earth are aligned (during full moons and new moons), it results in spring tides, which are the highest high tides and lowest low tides.

Front

Which Moon position produces the highest high tides and lowest low tides?

Back

The position where the Moon is closest to being aligned with the Sun and Earth.

Front

At which positions of the Moon is an eclipse of the Sun or Moon possible?

Back

Eclipses can occur when the Moon is at positions 1 and 5, where it aligns with the Earth and Sun.

Front

What is a lunar eclipse?

Back

A lunar eclipse occurs when the Earth passes between the Sun and the Moon, causing the Earth's shadow to cover the Moon.

Front

What is a solar eclipse?

Back

A solar eclipse occurs when the Moon passes between the Earth and the Sun, blocking the Sun's light from reaching Earth.

Front

What are spring tides?

Back

Spring tides are the highest high tides and lowest low tides that occur when the Sun, Moon, and Earth are aligned.

Front

What are neap tides?

Back

Neap tides are the lower high tides and higher low tides that occur when the Sun and Moon are at right angles relative to Earth.

Front

How does the distance of the Moon from Earth affect tides?

Back

The closer the Moon is to Earth, the stronger its gravitational pull, resulting in higher tides.
