Sun / Moon / Earth (SOL 4.6)

Front

Why does the Earth have seasons?

Back

Earth's axis is tilted as it moves around the Sun.

Answer explanation

The Earth has seasons because its axis is tilted as it orbits the Sun. This tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to seasonal changes.

Front

What season is the Northern Hemisphere in at position 4?

Back

winter

Answer explanation

At position 4, the Northern Hemisphere is in winter. This is because winter typically spans from December to February, and position 4 corresponds to the winter season.

Front

What season is the Southern Hemisphere in at position 1?

Back

fall

Answer explanation

In the Southern Hemisphere, seasons are opposite to those in the Northern Hemisphere. When it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere. Therefore, at position 1, the Southern Hemisphere is in fall.

Front

What is the difference between revolution and rotation of the Earth and the Moon?

Back

The Earth rotates about its axis and the Moon revolves around the Earth.

Answer explanation

The correct choice states that the Earth rotates about its axis, which means it spins on its own, while the Moon revolves around the Earth, indicating its orbit around our planet.

Front

Day and night are caused by the _____________ of the Earth.

Back

rotation

Answer explanation

Day and night occur due to the rotation of the Earth on its axis. As the Earth rotates, different parts face the Sun, creating day, while the opposite side experiences night.

Front

As the Earth travels around the Sun, this tilt causes different areas of the Earth’s surface to get different amounts of daylight at different times of the year. The angle of the Sun’s rays to the surface also causes areas to have more or less of the Sun’s energy. This causes the ________.

Back

seasons

Answer explanation

The tilt of the Earth affects how much sunlight different areas receive throughout the year, leading to variations in temperature and daylight. This variation is what causes the seasons.

Front

Arnav observes the Moon seems to change shape from day to day in a cycle that lasts about a month as it goes through: revolutions, phases, rotations, eclipses

Back

phases

Answer explanation

The moon appears to change shape due to its phases, which are the different illuminated portions visible from Earth as it orbits. This cycle lasts about a month, making 'phases' the correct answer.

Front

Mia is stargazing and notices that she can't see the Moon at all. Which Moon phase is she observing?

Back

new moon

Answer explanation

The new moon phase occurs when the moon is positioned between the Earth and the Sun, making it invisible from Earth. Therefore, during a new moon, you can't see the moon at all.

Front

Name this Moon phase.

Back

1st quarter moon

Answer explanation

The 1st quarter moon occurs when half of the moon is illuminated and visible from Earth. This phase is characterized by a right half being lit, distinguishing it from the new moon, last quarter, and waning gibbous phases.

Front

What is this Moon phase?

Back

full moon

Answer explanation

The full moon occurs when the moon is on the opposite side of the Earth from the sun, fully illuminating its surface. This phase is characterized by a bright, round appearance, distinguishing it from the other phases.
