Astronomy Review AKS 5a-5e

Which question would BEST explain why scientists now use Model 2 to describe Earth’s position in the solar system?

• Did new evidence change our understanding of the position of the Earth and sun?

• Did the position of the Earth and sun change over time in the solar system?

• Did new planets form and change the relative position of the sun and Earth?

• Did the sun’s position change over time in the solar system?

Use the information and models to answer the following questions. A student is creating a model of the Milky Way and the position of our solar system within the galaxy. Which model, if answered, will best help you predict how the model of the Milky Way will look in the future?

• A. How will the Milky Way expand and get larger as a result of the Big Bang?

• B. How will the Milky Way contract and get smaller as a result of the Big Bang?

• C. How will the Milky Way continue to move outward as a result of the Big Bang?

• D. How will the Milky Way change shape and composition as a result of the Big Bang?

Use the information and table provided to determine which of the following conclusions can be drawn about the planets.

• Earth’s mass is less than each of the inner planets.

• Earth has a higher density than each of the gas giants.

• Earth’s size is larger than Mercury but smaller than Mars.

• Earth is closer in distance from the Sun than Venus but further than Jupiter.

Students are observing the planets in our solar system and planetary motion. Based on the data in the table, which of the following explains the relationship between the distance of the planet from the Sun and its planetary motion around the sun?

• The planets with the greatest distance from the sun experience a longer time of revolution and shorter days of rotation.

• The planets with the greatest distance from the sun experience a longer time of revolution and longer days of rotation.

• The planets with the least distance from the sun experience a longer time of revolution and shorter days of rotation.

• The planets with the least distance from the sun experience a shorter time of revolution and shortest days of rotation.

Which of the following conclusions can they draw based on the information available?

• The outer planets have a greater density and smaller diameter than the inner planets.

• The outer planets are closer to the sun and have a larger mass than the inner planets.

• The inner planets are closer to the sun and have a larger diameter than the outer planets.

Using a string, a ball, and a hollow tube for a handle, a student makes a model as shown below. 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 the student's model illustrates the effect of gravity?

• the ball

• the string

• the handle

• the rotation direction

Use the model to answer the following question: What would MOST LIKELY happen if the sun's gravitational pull no longer existed?

• The planets would float off into space because without the sun inertia would no longer exist, and the planets would stop moving forward.

• 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.

A student is observing an image of an object that could be a comet, meteoroid or asteroid. Which of the following questions would BEST confirm that the object is a comet?

• How big is the object?

• Where is the object found?

• Does the object contain ice?

• Does the object contain metals?

Considering the effects of gravity in our solar system, which model best explains the orbital paths of comets as they travel through the solar system?

• A. A model where comets follow a strict circular orbit around the sun.

• B. A model where comets follow a highly elliptical orbit around the sun.

• C. A model where comets do not orbit the sun but move randomly.

• D. A model where comets orbit the Earth instead of the sun.
