Unit 6: Seasons & Moon Phases

Front

What are tides?

Back

Tides are the cycle of rising and falling ocean water that occurs due to the gravitational pull of the moon and the sun, repeating approximately every 12.5 hours.

Front

Why do we always see the same side of the moon from Earth?

Back

Because the moon rotates and revolves around the Earth at the same rate, making one complete turn on its axis in the same time it takes to orbit the Earth.

Front

What causes the seasons on Earth?

Back

The seasons are caused by Earth's tilted axis and its revolution around the sun, leading to varying angles of sunlight throughout the year.

Front

What is a Neap Tide?

Back

A Neap Tide occurs when the moon is in a position where its gravitational pull is perpendicular to that of the sun, resulting in lower high tides and higher low tides.

Front

What is a Spring Tide?

Back

A Spring Tide occurs when the sun, moon, and Earth are aligned, resulting in higher high tides and lower low tides.

Front

How long does it take for tides to cycle?

Back

Tides cycle approximately every 12.5 hours.

Front

What happens to the northern hemisphere when it is tilted away from the sun?

Back

When the northern hemisphere is tilted away from the sun, it experiences winter, not summer.

Front

What is the role of Earth's rotation in the day-night cycle?

Back

Earth's rotation on its axis causes different parts of the planet to receive sunlight, creating day and night.

Front

What is the difference between rotation and revolution?

Back

Rotation is the spinning of Earth on its axis, while revolution is the movement of Earth around the sun.

Front

What is the significance of the moon's phases?

Back

The moon's phases are the different appearances of the moon as seen from Earth, caused by the changing positions of the moon, Earth, and sun.
