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 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

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

Which statement explains why Venus has a higher and more constant surface temperature than Earth?

• Venus has a smaller mass and smaller orbit than Earth

• Venus rotates more rapidly and is under higher gravitational force than Earth

• Venus has a thicker atmosphere and a lesser degree of tilt on its axis than Earth

• Venus is covered with clouds of sulfur dioxide and the clods reflect more light than the clouds on Earth

Which of the following is an accurate comparison of Earth and Neptune?

• Neptune has a more solid surface than Earth

• Neptune has a longer period of rotation than Earth

• Neptune has a longer period of revolution than Earth

• Neptune has a higher than average temperature than Earth
