Tides Flashcard

Front

What are tides?

Back

Tides are the regular rise and fall of sea levels caused by the gravitational forces exerted by the Moon and the Sun on Earth.

Front

What causes high and low tides?

Back

High tides occur when the gravitational pull of the Moon and the Sun is strongest, while low tides occur when their pull is weakest.

Front

What is a Spring Tide?

Back

A Spring Tide is 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 Neap Tide occurs when the Moon is at a right angle to the Earth and Sun, resulting in lower high tides and higher low 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 Moon in tides?

Back

The Moon has a significant influence on Earth's tides due to its gravitational pull, which is stronger than that of the Sun.

Front

What is the role of the Sun in tides?

Back

The Sun also affects tides, but its influence is less than that of the Moon. It contributes to the variation in tide heights.

Front

What is the time difference between two high tides?

Back

There is approximately 12 hours between one high tide and the next high tide.

Front

During which moon phases are tides the highest?

Back

Tides are highest during the New Moon and Full Moon phases.

Front

What happens to the gravitational pull during a Spring Tide?

Back

The gravitational pull on Earth becomes stronger during a Spring Tide due to the alignment of the Earth, Moon, and Sun.
