2/11/25 Understanding Day and Night Quiz

What is the imaginary line around which Earth spins called?

• Equator

• Axis

• Orbit

• Meridian

How long does it take for Earth to complete one full rotation on its axis?

• 12 hours

• 24 hours

• 48 hours

• 365 days

What causes the cycle of day and night on Earth?

• The Moon's phases

• Earth's rotation

• The Sun's brightness changes

• Earth's revolution around the Sun

Why don't we feel Earth's rotation?

• Because it is too slow.

• Because Earth's gravity keeps us on the ground & our size compared to the size of the Earth.

• Because the Sun's gravity counteracts it.

• Because the atmosphere blocks it.

Explain why one side of Earth experiences daytime while the other side experiences nighttime.

• Because the Sun moves around Earth

• Because Earth rotates, causing one side to face the Sun

• Because the Moon blocks sunlight on one side

• Because Earth's orbit changes daily

How does the Moon affect Earth, according to the passage?

• It causes day and night

• It affects the tides and provides reflected sunlight at night

• It changes Earth's rotation speed

• It controls Earth's orbit

What reasoning can you provide to explain why we don't feel Earth's rotation despite its high speed?

• The rotation is too slow to notice

• Earth's gravity and smooth rotation prevent us from feeling it

• The atmosphere absorbs the motion

• The Sun's gravity counteracts the motion

The Earth's axis is tilted at 23.5 degrees. Predict what might happen to Earth's day and night cycle if its axis were tilted at 35 degrees.

• Days and nights would be equal everywhere

• There would be more much longer differences in day and night lengths

• The cycle would stop completely

• The Sun would rise in the west

How does Earth's rotation contribute to the concept of time zones?

• It doesn't; time zones are based on the Moon

• Earth's rotation causes different parts of the world to experience day and night at different times

• Time zones are based on Earth's orbit around the Sun

• Time zones are determined by the Sun's brightness

Evaluate the statement: "The Sun's movement across the sky is due to Earth's rotation." Is this statement true or false? Justify your answer.

• True, because Earth's rotation makes the Sun appear to move

• False, because the Sun actually moves around Earth

• True, because the Sun's brightness changes

• False, because the Moon causes the Sun to move
