.   Temperatures on Mars reach as high as 20 °C and fall as low as -120 °C. That temperature is colder than any place on Earth. Temperatures on Earth vary, but they stay within a range of -89 °C to 58 °C. Which of these physical properties is responsible for the greater range of temperatures on Mars as compared to those on Earth?

a)

Mass

b)

Thin atmosphere

c)

Period of revolution

d)

Axial tilt

2.

The distance between objects along with the masses of the objects affect the gravitational force between the objects. Which statement is true according to Newton’s law of universal gravitation?

a)

When the masses of objects increase, gravitational force decreases

b)

When distance between objects increases, gravitational force decreases

c)

When distance between objects decreases, gravitational force decreases

d)

When the masses of objects decrease, the distance between objects decreases

3.

The surface of Mercury has many more craters than the surface of Earth has. Which of the following statements best explains why Mercury has many more craters than Earth has?

a)

Mercury has a thinner atmosphere than Earth has

b)

Mercury rotates faster than Earth does

c)

Mercury has a smaller mass than Earth does

d)

Mercury is closer to the Sun that Earth is

4.

What is a way that the properties of the gas giants could cause the number of moons that orbit each planet to differ greatly from the number of moons that orbit Earth?

a)

Gas giants are more massive than Earth and thus have greater gravitational forces, so they could attract more objects

b)

Gas giants are farther from the sun than Earth, so there are fewer objects in that part of space to attract into orbits

c)

Gas giants are less dense than Earth, so they contain less material that could form natural satellites

d)

Gas giants rotate more rapidly than Earth, so they eject more material that could form natural satellites

5.

Eric is creating a timeline of the formation of the solar system. Which flow chart best describes the formation of the solar system?

a)

Solar nebula – nuclear fusion – sun – planets – planetesimals – protoplanetary disk

b)

Protoplanetary disk – nuclear fusion – sun – solar nebula – planetesimals – planets

c)

Solar nebula - protoplanetary disk – nuclear fusion – planetesimals – planets – sun

d)

Solar nebula – protoplanetary disk – nuclear fusion – sun – planetesimals – planets

6.

The table below shows some physical properties of the gas giant planets. What can you conclude about the period of rotation of the gas giant planets?

a)

The smallest gas giant planet rotates the fastest

b)

The planet with the smallest gravity rotates the fastest

c)

The planet with the largest axial tilt rotates the fastest

d)

The largest gas giant planet rotates the fastest

7.

Teresa is studying the solar system. She learns that Jupiter has 18 named moons as well as many small unnamed ones, and that Earth has just one moon. Which of the following best explains why Jupiter has so many more moons than Earth?

a)

Jupiter has a thicker, denser atmosphere than Earth and it condenses rock particles to form moons

b)

Jupiter is much farther away from the Sun than Earth, so it attracts more moons

c)

Jupiter has a much greater mass, and therefore a greater gravitational pull, than Earth

d)

Jupiter is so much colder than Earth that clumps of ice form moons in its upper atmosphere more readily

8.

People sometimes talk about seeing shooting stars. What do they actually see?

a)

A meteor that burns up in the atmosphere close enough to see

b)

A meteoroid traveling through space

c)

A meteorite that burns up in the atmosphere close enough to see

d)

A comet that has come close enough to Earth’s atmosphere to be seen

9.

This diagram shows part of the Solar System. In addition to several planets, the diagram includes a band of small objects that orbit the sun.

 

Which objects are located in orbit between Mars and Jupiter?

a)

Comets

b)

Meteorites

c)

Kuiper Belt objects

d)

Asteroids

10.

Why does Aristarchus’ idea that the sun is much larger than Earth support the heliocentric theory of the Solar System?

a)

Small objects rotate around large objects

b)

Small objects revolve around large objects

c)

Large objects rotate around small objects

d)

Large objects revolve around small objects

11.

Why is the composition of the inner planets different from that of the outer planets?

a)

The inner planets formed from heavier elements. The lighter elements that were left over formed into larger outer planets

b)

The inner planets formed from lighter elements. The heavier elements that were left over formed into larger outer planets

c)

The outer planets formed from heavier elements. The lighter elements that were left over formed into larger inner planets

d)

The outer planets formed from lighter elements. The heavier elements that were left over formed into larger inner planets

12.

Many historical models of the solar system were geocentric. Which of these phrases describes a geocentric solar system?

a)

Circular, orbital path of travel

b)

Existing in a star system

c)

The sun as a reference point

d)

Earth as a reference point

13.

Which of the following best explains how modern astronomers view Galileo’s model of the solar system?

a)

Modern astronomers would suggest the Sun is not the exact center of the solar system, but would agree that the Sun is not revolving around the Earth

b)

Modern astronomers would disagree with Galileo’s entire model of the solar system

c)

Modern astronomers would suggest that Galileo was wrong about almost everything except the position of the Sun in the solar system

d)

Modern astronomers would disagree with Galileo’s idea that the planets revolve around the Sun, but would agree with his arrangement of the planets

14.

Hillary is studying Kepler’s law of planetary motion. She learns that each planet follows an elliptical orbit around the Sun, as shown in the diagram below. Which statement below best explains why the planets orbit the Sun?

a)

The forces between each of the planets keep them in orbit

b)

The planets are drawn into orbit by the magnetic force of the Sun

c)

The gravitational force of the Sun keeps the planets in orbit

d)

The constant velocity of each planet keeps it moving in orbit around the Sun

15.

a)

Astrology does not involve topics that are of any concern to most people
