Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, such as the Earth and objects on it.

What causes ocean tides?

Back

Ocean tides are caused by the gravitational pull of the moon and the sun on Earth's ocean waters.

What is a tidal range?

Back

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

What is a strong gravitational pull?

Back

A strong gravitational pull occurs when the gravitational force is significant, leading to larger tidal ranges.

Front

What is a weak gravitational pull?

Back

A weak gravitational pull occurs when the gravitational force is less significant, leading to smaller tidal ranges.

Front

During which moon phases do the largest tidal ranges occur?

Back

The largest tidal ranges occur during the new moon and full moon phases.

What is the role of the moon in ocean tides?

Back

The moon's gravitational pull is the primary force that causes ocean tides on Earth.

What is the role of the sun in ocean tides?

Back

The sun also exerts a gravitational pull on Earth's oceans, but its effect is less than that of the moon.

Front

How does the position of the moon affect tides?

Back

The position of the moon relative to the Earth affects the strength of its gravitational pull, influencing the height of tides.
