Exam Review 3

Front

What is a New Moon?

Back

A New Moon is the phase of the moon when it is not visible from Earth because it is positioned between the Earth and the Sun.

Front

What causes tides on Earth?

Back

Tides are caused by the gravitational pull of the moon and the sun on Earth's oceans.

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.

Front

What is a low tide?

Back

A low tide is the point at which the water level is at its lowest, occurring between high tides.

Front

What are Spring Tides?

Back

Spring Tides occur during the new moon and full moon phases when the gravitational forces of the moon and sun align, resulting in higher high tides and lower low tides.

Front

What are Neap Tides?

Back

Neap Tides occur during the first and third quarters of the moon when the gravitational forces of the moon and sun are perpendicular, resulting in lower high tides and higher low tides.

Front

How often do tides occur?

Back

Tides generally occur twice a day, alternating between high and low tides.

Front

What is the average time between high and low tides?

Back

The average time between high and low tides is about 6 hours.

Front

What is the tidal bulge?

Back

The tidal bulge is the area of water that is raised due to the gravitational pull of the moon, resulting in high tide.

Front

What happens to the water on the side of Earth opposite the moon?

Back

There is also a tidal bulge on the side of Earth opposite the moon, resulting in a second high tide.
