Seasons

What are the four seasons?

• Spring, Summer, Autumn, Winter

• Day, Night, Morning, Evening

• Hot, Cold, Rainy, Windy

• January, February, March, April

What causes the four seasons on Earth?

• The distance from Earth to the Sun

• The rotation of Earth on its axis

• The tilt of Earth's axis

• The gravitational pull of the Moon

What defines 'one day' on Earth?

• The time it takes for Earth to orbit the Sun

• The time it takes for the Moon to orbit Earth

• The time it takes for Earth to rotate on its axis

• The time it takes for Earth to complete a full revolution

What defines 'one year' on Earth?

• The time it takes for Earth to orbit the Sun

• The time it takes for the Moon to orbit Earth

• The time it takes for Earth to rotate on its axis

Why is a globe tilted?

• To make it easier to hold

• To represent the Earth's axis

• To create a more realistic model

• To align with the Sun's position

What is a 'solstice' when does it occur?

• The longest/shortest day of the year, occurring in June or December

• The shortest day of the year, occurring in September or March

• The day when day and night are equal in length, occurring in March or September

• The day when the Sun is directly overhead at noon, occurring in March or September

What is an 'equinox' and when does it occur?

• The longest day of the year, occurring in June or December

• The shortest day of the year, occurring in June or December

• The day when day and night are equal in length, occurring in March or September

• The day when the Sun is directly overhead at noon, occurring in March or September

What is the astronomical significance of Earth's equator?

• It marks the division between the Northern and Southern Hemispheres

• It marks the division between the Tropics of Cancer and Capricorn

• It marks the division between the Arctic and Antarctic circles

• It marks the division between the Prime Meridian and the International Date Line

Do regions along the equator experience seasons? Why or why not?

• Yes, because of the tilt of Earth's axis

• Yes, because of the distance from Earth to the Sun

• No, because the equator is always at the same angle to the Sun

• No, because the equator is always in darkness

What is the astronomical significance of the Arctic and Antarctic circles?

• They mark the division between the Northern and Southern Hemispheres

• They mark the division between the Tropics of Cancer and Capricorn

• They are the points that are just able to see the Sun on the solstices (Arctic in Dec and Antarctic in June)

• They mark the division between the Prime Meridian and the International Date Line
