Solar System and Objects

What is the difference between the heliocentric model and the geocentric model of the solar system?

• In the heliocentric model the Sun is at the center of the solar system and in the geocentric model the Earth is at the center of the solar system.

• In the heliocentric model the Earth is at the center of the solar system and in the geocentric model the Sun is at the center of the solar system.

• In the heliocentric model there are 5 planets in our solar system and in the geocentric model there are 9 planets in our solar system.

• In the heliocentric model the planets rotate clockwise around the Sun and in the geocentric model the planets rotate counterclockwise around the Sun

Which set of characteristics are true of only the inner planets?

• Gaseous, large

• Cool, wet

• Cratered, liquid

• Terrestrial, small

• Wet, cratered

The biggest difference between the geocentric and heliocentric models of the solar system is how they describe the Sun or Earth in terms of which of the following?

• Their location and motion

• Their masses

• Their ages

• Their size and shape

• Their color and apparent magnitude

What is true of the planets that are furthest from the Sun?

• They are smaller

• The sun's gravitational pull is greater on those planets

• Their orbit is shorter

• Their temperature increases

• Their temperature decreases

The diagrams provided here show three different configurations of the relative positions and motions of the Earth and the Sun.

Choose the answer that correctly labels the diagram with heliocentric or geocentric.

• Model 1 = heliocentric; Model 2 = geocentric

• Model 2 = heliocentric, Model 3 = geocentric

• Model 1 = heliocentric, Model 3 = geocentric

• Model 1 = geocentric, Model 3 = heliocentric

• Model 1 = heliocentric, Model 3 = heliocentric

The inner planets in our solar system are small and terrestrial. Which set of characteristics is unique to the outer planets?

• Gaseous, liquid

• Terrestrial, small

• Cool, wet

• Rocky, small

• Rocky, large

Which of the following represents the biggest difference between the geocentric and heliocentric models of the solar system?

• The gravitational pull on objects in the solar system

• The amount of energy represented as radiation

• The absolute and apparent magnitude of the stars around the planets

• The history of the formation of the solar system

• The object the solar system is revolving around

What is true of the planets that orbit further from the Sun?

• The rockier the surface of the planet

• The thicker the planet's atmosphere

• The longer it takes to orbit the Sun

• The redder the planet appears

Mr. J Lamont is drawing a model of the solar system on the white board. If he is representing the heliocentric model of the solar system, which of the following should be in the center of his model?

• The Sun

• Mars

• Jupiter

• Earth

• The Moon

Ms. Collazo is drawing the geocentric model of our solar system which we now know is incorrect on her white board. What would be at the center of her model?

• The Sun

• The Moon

• The Earth

• Jupiter
