Solar System

What does the heliocentric model suggest?

• that planets move around the earth

• that the sun moves around the earth

• that everything in our solar system orbits the sun

• that the earth is in the center of the solar system

Which statement explains what the geocentric model of the solar system stated?

• The sun is the center of our solar system

• The earth is the center of our solar system

• The earth revolves around the sun

• The planets revolve around the sun

Which of the following observations does NOT provide evidence for the heliocentric model?

• planets move in elliptical orbits

• comets move in regular, elliptical orbits\

• venus shows phases, just like the moon

• earth's gravitational pull keeps its moon in orbit

Which would most likely happen to the motion of the planets without the force of gravity from the Sun?

• planets would continue to move in large ellipses

• planets would drift away from the sun into outer space

• planets would slow down and eventually stop moving

• planets would gradually make smaller and smaller ellipses

Asteroids A and B are 5 meters apart. Asteroids C and D are also 5 meters apart.Asteroids A and B are both 5 kilograms, and asteroids C and D are both 7 kilograms. Which set of asteroids will have a stronger/greater gravitational attraction?

• C and D, because gravitational attraction is greatest with increased mass

• A and B, because gravitational attraction is greatest with decreased mass

• A and B, because gravitational attraction is greatest with increased distance

• C and D, because gravitational attraction is greatest with increased distance

Which of the following best describes why scientists began to believe the heliocentric theory, instead of the geocentric theory?

• The geocentric theory was supported by additional evidence

• The geocentric theory proved that the Sun is the center of the universe

• the heliocentric theory was based on several well-established scientific laws

• the heliocentric theory was better supported by data explaining the motion of the planets and other bodies in the Solar System

How is energy transferred from the core of the Sun to its outer layers?

• energy radiates outward from the core as visible light

• energy is carried inward from the outer layers by convection

• energy is radiated out from the core first, then carried to the outer layers by convection

• energy is carried out from the core by convection first, then radiated to the outer layers

We want to create a computer model of the Sun's rotation. Which of the following designs would be most accurate?

• we should show the Sun rotating at the same rate as Earth

• we should show the Sun rotating more rapidly at its equator than at its poles

• we should show the Sun rotating and revolving in exactly the same period of time

• we should show the interior and exterior of the Sun rotating at the same rate of speed

Which statement describes sunspots?

• they have a bright white appearance

• they occur in the radiation zone of the Sun

• they occur in areas of extremely low magnetic fields

• they have lower temperatures than their surroundings

The Sun's magnetic field can sometimes get tangled up as the Sun rotates. These tangled magnetic fields lift extra energy to the surface in an explosive event that releases solar material into space. Which solar event is being explained?

• auroras

• flares

• prominences

• sunspots
