Understanding Earth's Geography and Movements

What event marks the beginning of everything in the universe?

• Formation of the Solar System

• The creation of Earth

• The Big Bang

• Formation of the Milky Way

How fast is Earth spinning at the equator?

• 13 times faster than a cheetah

• 830 kilometers per hour

• 120 kilometers per hour

• 1600 kilometers per hour

How does the Earth's speed at the equator compare to that of a cheetah?

• It's slower

• It varies depending on the time of day

• It's about the same

• It's faster

What causes Earth to wobble?

• The Moon's gravitational pull

• Human activities

• Melting ice from Antarctica and Greenland

• All of the above

What is precession?

• The cycle of the seasons

• The shift in the magnetic poles

• The wobble in Earth's rotation on its axis

• The change in Earth's orbit shape

What effect does human water use have on Earth's rotation?

• It has no effect

• It speeds it up

• It slows it down

• It causes the Earth to wobble

Why do we have leap years?

• To compensate for the extra quarter day in Earth's orbit

• To adjust for Earth's rotation speed

• To celebrate a special event

• To align the calendar with the lunar cycle

Why does the Earth have an elliptical orbit?

• Due to the gravitational pull of the Sun

• Because of the Moon's influence

• It's a result of the Big Bang

• All planets have elliptical orbits due to their formation process

What causes the seasons to change?

• Earth's distance from the Sun

• The tilt of Earth's axis

• The Moon's orbit around Earth

• Earth's rotation speed

What is the term used for incoming solar radiation?

• Insolation

• Photosynthesis

• Solar wind

• Solar flare
