Tides Practice

Front

What causes a Spring Tide?

Back

A Spring Tide occurs when the sun, moon, and Earth are nearly in a line, causing the gravitational pull to be stronger and resulting in higher high tides and lower low tides.

Front

Why does the Moon have a greater influence on Earth tides than the Sun?

Back

The Moon has a greater influence on Earth tides than the Sun because it is closer to the Earth.

Front

What is the difference between Spring Tides and Neap Tides?

Back

Spring Tides occur when the Earth, sun, and moon are in line (during new or full moons), while Neap Tides occur when the sun and moon are at right angles to each other (during the first and third quarter phases).

Front

What happens during a Neap Tide?

Back

During a Neap Tide, the gravitational pull of the sun and moon are at right angles, resulting in lower high tides and higher low tides.

Front

What is a High Tide?

Back

A High Tide is the point at which the water level is at its highest due to the gravitational pull of the moon and sun.

Front

What is a Low Tide?

Back

A Low Tide is the point at which the water level is at its lowest due to the gravitational pull of the moon and sun.

Front

What is the tidal range?

Back

The tidal range is the difference in height between the high tide and the low tide.

Front

What is the effect of the Moon's gravity on Earth?

Back

The Moon's gravity pulls on the Earth's water, causing the water to bulge out, which creates tides.

Front

How often do tides occur?

Back

Tides typically occur twice a day, with two high tides and two low tides.

Front

What is the role of the Sun in tides?

Back

The Sun also exerts a gravitational pull on Earth’s water, but its effect is less than that of the Moon due to its greater distance.
