What causes day and night on Earth?

• The Earth's revolution around the Sun

• The Earth's rotation on its axis

Answer explanation

Day and night on Earth are caused by the Earth's rotation on its axis. As the Earth spins, different parts face the Sun, creating daylight, while the opposite side experiences night.

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

• 12 hours

• 24 hours

Answer explanation

The Earth takes 24 hours to complete one full rotation on its axis, which defines the length of a day. Therefore, the correct answer is 24 hours.

Which direction does the Earth rotate?

• From east to west

• From west to east

Answer explanation

The Earth rotates from west to east, which is why the sun appears to rise in the east and set in the west. This eastward rotation is the correct answer.

What is the main reason the Sun appears to move across the sky during the day?

• The Earth is rotating on its axis

• The Moon is blocking the Sun

Answer explanation

The Sun appears to move across the sky because the Earth is rotating on its axis. This rotation causes different parts of the Earth to face the Sun at different times, creating the illusion of the Sun's movement.

What is the term for the path the Sun appears to take across the sky?

• Orbit

• Ecliptic

Answer explanation

The term for the path the Sun appears to take across the sky is the 'Ecliptic'. This is the apparent path of the Sun against the background stars, as observed from Earth.

Why do we see different stars in the sky at different times of the year?

• The Earth's revolution around the Sun

• The Moon's phases

Answer explanation

We see different stars at different times of the year because of the Earth's revolution around the Sun. As the Earth orbits, our night sky changes, revealing different constellations and stars throughout the seasons.

What causes the apparent movement of the Moon across the sky?

• The Moon's rotation on its axis

• The Earth's rotation on its axis

Answer explanation

The apparent movement of the Moon across the sky is primarily due to the Earth's rotation on its axis. As the Earth spins, it creates the illusion that the Moon is moving, while the Moon itself is relatively stationary in its orbit.

How long does it take for the Moon to orbit the Earth?

• 24 hours

• 29.5 days

Answer explanation

The Moon takes approximately 29.5 days to complete one orbit around the Earth. This period is known as a lunar month, which is significantly longer than 24 hours.

What is the term for the imaginary line that the Earth rotates around?

• Axis

• Meridian

Answer explanation

The term for the imaginary line that the Earth rotates around is called the 'Axis'. The meridian refers to lines of longitude, which are not related to the rotation of the Earth.

Which of the following is true about the stars' movement in the night sky?

• Stars move because the Earth is stationary

• Stars move because the Earth rotates

Answer explanation

Stars appear to move across the night sky due to the rotation of the Earth on its axis. As the Earth spins, different stars come into view, creating the illusion of movement.
