Moon Phases/Ocean Tides Pin Wheel

Front

What causes ocean tides on Earth?

Back

The gravitational pull from the moon and the sun causes ocean tides on Earth.

Front

Why does the moon's gravitational pull have a greater effect on tides than the sun's?

Back

The moon is closer to the Earth than the sun, making its gravitational pull stronger on the oceans.

Front

What are the two types of tides?

Back

The two types of tides are high tides and low tides.

Front

What is a high tide?

Back

A high tide is when the water level in the ocean rises to its highest point.

Front

What is a low tide?

Back

A low tide is when the water level in the ocean falls to its lowest point.

Front

What is the role of the sun in ocean tides?

Back

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

Front

What is a tidal cycle?

Back

A tidal cycle is the regular rise and fall of sea levels caused by the gravitational forces of the moon and sun.

Front

How often do tides occur?

Back

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

Front

What is a spring tide?

Back

A spring tide is a tide that occurs when the sun, moon, and Earth are aligned, resulting in higher high tides and lower low tides.

Front

What is a neap tide?

Back

A neap tide is a tide that occurs when the sun and moon are at right angles to each other, resulting in lower high tides and higher low tides.
