Earth Science - Moon Flashcard

Front

What is the Moon's position A in relation to Earth?

Back

Position A refers to a specific location in the Moon's orbit around Earth, affecting its visibility and phase as seen from Earth.

Front

What causes the phases of the Moon?

Back

The phases of the Moon are caused by the changing angles of sunlight hitting the Moon as it orbits Earth, resulting in different portions of the Moon being illuminated.

Front

What is a lunar eclipse?

Back

A lunar eclipse occurs when the Earth is positioned directly between the Sun and the Moon, causing the Earth's shadow to fall on 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 the lowest low tides that occur when the Sun, Moon, and Earth are aligned (during full and new moons).

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 (during the first and third quarters of the moon).

Front

How does the Moon's gravitational pull affect Earth?

Back

The Moon's gravitational pull causes tides in Earth's oceans, leading to the rise and fall of sea levels.

Front

What is the significance of the Moon's orbit?

Back

The Moon's orbit affects its phases, eclipses, and the timing of tides on Earth.

Front

What is the difference between a waxing and waning Moon?

Back

A waxing Moon is increasing in illumination (from new to full), while a waning Moon is decreasing in illumination (from full to new).

Front

What is the appearance of the Moon at position P?

Back

The appearance of the Moon at position P can be determined by its phase, which is influenced by its position relative to Earth and the Sun.
