Exploring the Dynamics of Spaceship Earth

What shape does Earth's orbit around the Sun take?

• Circle

• Rectangle

• Ellipse

• Spiral

Why is it colder during January even though Earth is closest to the Sun?

• Increased distance from the Sun

• Earth's speed decreases

• Sun's light is less intense

• Axial tilt of Earth

How does Earth's axial tilt affect the seasons?

• It has no effect

• Increases Earth's speed

• Causes longer days in summer

• Changes Earth's orbit

What is the speed of Earth as it travels through space?

• 30,000 km/h

• 107,000 km/h

• 125,000 km/h

• 50,000 km/h

What effect does Earth's tilt have on the angle of sunlight in different hemispheres?

• Decreases sunlight in the north

• Increases heat in the tropics

• Spreads sunlight over a larger area in the north

• No effect

Which planet orbits just next to Earth?

• Mars

• Venus

• Saturn

• Jupiter

Why do we see Venus in the morning at certain times?

• It is behind the Sun

• It is above the Sun

• It is below the Sun

• It is to the right of the Sun

What is the primary difference between a planet and a star?

• Stars emit their own light

• All of the above

• Planets are smaller

• Planets are closer

How long would it take to reach Sirius if Earth left its orbit?

• 16 days

• 100 years

• 80,000 years

• 1,000 years

How long would it take to reach Venus at Earth's normal cruising speed?

• 80,000 years

• 16 days

• 30 days

• 1 year
