Sun-Earth-Moon System

Front

What is the primary reason the Moon has a greater influence on Earth tides than the Sun?

Back

The Moon is closer to the Earth.

Front

What type of tide occurs when the Earth, Moon, and Sun are at right angles to each other?

Back

Neap tide.

Front

Why do solar eclipses not occur every month?

Back

The Moon's orbit is tilted relative to the Earth's orbit around the Sun.

Front

What is the main difference between spring tides and neap tides?

Back

Spring tides occur when the Earth, Moon, and Sun are aligned (during new or full moons), while neap tides occur when they are at right angles.

Front

What causes tides on Earth?

Back

Differences in the gravitational pull of the Moon and the Sun on different sides of the Earth.

Front

What is a spring tide?

Back

A tide that occurs when the Earth, Moon, and Sun are in a straight line, resulting in higher high tides and lower low tides.

Front

What is a neap tide?

Back

A tide that occurs when the Earth, Moon, and Sun form a right angle, resulting in lower high tides and higher low tides.

Front

How often do spring tides occur?

Back

Spring tides occur approximately every two weeks, during the new and full moons.

Front

How does the tilt of the Moon's orbit affect eclipses?

Back

The tilt of the Moon's orbit means that it usually passes above or below the Sun from Earth's perspective, preventing a solar eclipse from occurring every month.

Front

What is the gravitational effect of the Sun on Earth's tides compared to the Moon?

Back

The Sun's gravitational effect on tides is less than that of the Moon due to its greater distance from Earth.
