Spaceling — The Sun & Rocky Planets Asteroid Run

Hi!

I'm Spaceling.

Welcome to Asteroid Run!

Will you help me investigate the sun & rocky planets?

The Grumblies have mixed up our clues.

Let's check the evidence!

The Sun is the solar system's main source of light and heat.

Mercury, Venus, Earth and Mars are rocky inner planets.

Which group contains rocky inner planets?

  • A. Only Jupiter and Saturn
  • B. Only Uranus and Neptune
  • C. Mercury, Venus, Earth and Mars

The answer is C: Mercury, Venus, Earth and Mars

The Sun is the solar system's main source of light and heat.

Mercury, Venus, Earth and Mars are rocky inner planets.

That clue helps us make sense of this place.

These worlds differ in atmosphere, surface conditions and size.

Being rocky does not mean a planet has Earth's air

or liquid surface water.

Where does much solar-system light come from?

  • A. Asteroid shadows
  • B. The Sun
  • C. Planet rings

The answer is B: The Sun

The Sun is the solar system's main source of light and heat.

Mercury, Venus, Earth and Mars are rocky inner planets.

Hmm...

how does that connect to our first clue?

Our table marks Earth with oceans of liquid water

and Mars with a thin atmosphere and a colder surface.

Use those recorded differences rather than assuming all rocky planets

are Earth copies.

Which table entry distinguishes Earth here?

  • A. Oceans of liquid water
  • B. An identical atmosphere to Mars
  • C. The same oceans on both planets

The answer is A: Oceans of liquid water

Our table marks Earth with oceans of liquid water

and Mars with a thin atmosphere and a colder surface.

Use those recorded differences rather than assuming all rocky planets

are Earth copies.

Nice investigating!
