A science class has been researching early models of the solar system. Each model shows the positions of the planets in relation to the earth and sun. The students cannot agree on which model best represents the modern day understanding of the solar system. Which student has the BEST explanation?
Karissa stated the model 1 was the correct model, since the planets rotate around the Earth.
Jeff stated the model 2 was the correct model, since the planets revolve around the sun.
Jessie stated the model 1 was the correct model, since the planets rotate around sun.
Nicole stated the model 1 was the correct model, since the planets revolve around the Earth.
Many scientists accepted the model that all objects in the universe revolve around the Sun. What did they learn that made them change this model?
Stars do not revolve around the Sun.
Planets do not revolve around the Sun.
Comets do not revolve around the Sun.
Asteroids do not revolve around the Sun.

Science students are analyzing the planet data provided in the table below. What can they conclude based on the available information?
Earth’s mass is less than each of the inner planets.
Earth has a smaller diameter than each of the gas giants.
Earth’s size is larger than Mercury but smaller than Mars.
Earth is closer to the Sun than Venus but further than Jupiter.
What do the four outer planets have in common?
They are much larger than Earth and are solid.
They are about the same size as Earth and are solid.
They are much larger than Earth and do not have solid surfaces.
They are about the same size as Earth and do not have solid surfaces.
An astronomer has been collecting research on heavenly bodies in the solar system. Which of the following conclusions can he draw based on the information provided?
Table A describes characteristics of comets while Table B describes characteristics of asteroids.
Table A describes characteristics of asteroids while Table B describes characteristics of comets.
Table A describes characteristics of the inner planets while Table B describes characteristics of the outer planets.
Table A describes characteristics of the outer planets while Table B describes characteristics of the inner planets.
Venus has the highest surface temperature of all the planets in our solar system. Which is the best explanation for this?
Venus's atmosphere has thick clouds and carbon dioxide which causes more thermal radiation to be absorbed.
Venus is very close to the sun which causes causes a strong greenhouse effect.
Venus is very close to the sun which causes more thermal radiation to be absorbed.
Venus's atmosphere has thick clouds and carbon dioxide which causes a strong greenhouse effect.
The data table below compares features of several planets. Which of the following conclusions can you draw based on the information provided?
Planets closer to the Sun have slower orbital speeds because they are smaller.
Planets closer to the Sun have a longer period of rotation than period of revolution because of their elliptical orbits.
Planets further from the Sun have faster orbital speeds and shorter periods of revolution because of the Sun’s energy.
Planets further from the Sun have slower orbital speeds and longer periods of revolution because of the Sun’s gravity.
Which is true about the density of Jupiter compared to the density of Earth?
Jupiter is denser than Earth because it is made of gas.
Jupiter is denser than Earth because it is made of rock.
Jupiter is less dense than Earth because it is made of gas.
Jupiter is less dense than Earth because it is made of rock.
Scientists observe a planet in a distant galaxy. This planet appears to have similar features to Earth. Which feature would the scientists be most interested in, if they were looking for life on this planet?
thick atmosphere
liquid water
active volcanoes
long day length
Using a string, a ball, and a hollow tube for a handle, Julie makes a model as shown in the image to the right. Holding the center of the handle, she swings the ball in a circle to show how Earth orbits the sun. She knows that the orbit of Earth depends upon the gravitational pull. Which component of Julie’s model illustrates the effect of gravity?
ball
string
handle
direction of rotation
The model below illustrates that the Sun's gravity holds each planet in its orbit. Neptune is farther away from the Sun than is Earth. Students in an Earth science class were asked to revise the model to include an explanation of how the effect of the Sun's gravity on Neptune compares with the effect of the Sun's gravity on Earth. Four student’s explanations are presented below. Which student’s explanation is best?
Student 1: The Sun has less gravitational pull on Earth because it is closer.
Student 2: The Sun has less gravitational pull on Neptune because it is bigger.
Student 3: The Sun has the same gravitational pull on all planets that are in orbit.
Student 4: The Sun has less gravitational pull on Neptune because it is farther away.
Gravity and inertia keep the planets in orbit. What would happen if we did not have inertia?
The Earth would continue in a straight line out in space.
The Earth would stay still, in its current place.
The Earth would be pulled into the Sun.
The Earth would become part of the Oort Cloud.
The model below was created by a student in Earth science class to show gravity and inertia working together to create an orbit path. The model illustrates that the Sun is the largest object in the Solar System, and the planets and other objects in the Solar System all revolve around the sun. Which of the following best explains how this model would need to be revised if the sun did not exist?
The planets would start crashing into each other because the forward motion of inertia would pull them toward each other
The planets would start crashing into each other because without the sun gravity would pull all of the planets together
The planets would float off into space because the gravitational force of the sun would no longer be there.
The planets would float off into space because without the sun inertia would cease to exist and the planets would stop moving forward
Which question could you ask to determine if an object is a comet?
Is it composed of Iron and nickel?

Craters
Comets
Planetesimals
Meteoroids
