Seasons on Earth | Exit Quiz | Oak National Academy

The dashed blue line in the picture represents Earth's tilted {{}} of rotation.

• direction

• equator

• spin

• axis

Answer explanation

The dashed blue line in the picture represents Earth's tilted axis of rotation; the imaginary line around which the Earth is spinning.

In countries that have summers and winters, the seasons change because Earth’s tilted axis does not change ___ as Earth orbits the Sun.

Answer explanation

In countries that have summers and winters, the seasons change because Earth’s tilted axis does not change direction as Earth orbits the Sun.

Which statement about places at the equator is true?

• Places at the equator have warmer and colder seasons (summers and winters).

• Places at the equator stay close to being face-on to the Sun all year.

• The equator has summer in between when the northern and southern hemispheres do.

• The Sun's rays are always more spread out at the equator, than at Earth's poles.

Answer explanation

Places at the equator stay close to being face-on to the Sun all year, so places at the equator do not have warmer and colder seasons (summers and winters). The sun's rays are always less spread out at the equator than they are at Earth's poles.

Which month is represented in this image, and why? The pink lines are the paths of the UK and southern Chile as Earth spins. The yellow arrows are the Sun's rays.

• It is June because the nothern hemisphere has summer.

• It is June because the southern hemisphere has summer.

• It is December because the southern hemisphere is tilted away from the Sun.

• It is December because the southern hemisphere is tilted towards the Sun.

Answer explanation

In the picture, it is December because the northern hemisphere (UK) is tilted away from the Sun so has winter. The southern hemisphere is tilted towards the Sun so has summer.

Which of the statements help to explain seasons on Earth?

• Different places become more and less 'face on' to the Sun over a year.

• A place makes different angles to the Sun's rays over a year.

• Earth's tilt does not change direction as Earth orbits the Sun.

• The Sun's rays become more and less spread out over the ground over a year.

• Earth's tilt makes places closer and further from the Sun over a year.

Answer explanation

The seasons on Earth are explained by the different angles a place makes to the Sun's rays over a year, and these different angles are caused by Earth's tilt not changing direction as Earth orbits the Sun.
