Unit 6 : Inner and Outer Planets

Which of the following factors is most responsible for the difference in surface temperature between Earth and Venus?

• Earth's atmosphere contains more oxygen.

• Venus is closer to the Sun.

• Earth's surface is covered with water, which absorbs heat.

• Venus has a thicker atmosphere with more carbon dioxide.

What is the main reason Mars is much colder than Earth?

• Mars is farther from the Sun than Earth.

• Mars has a thinner atmosphere that cannot trap heat effectively

• Mars rotates faster, giving it shorter days and nights.

• Mars has a surface covered in ice.

Gravitational pull on a planet depends on its mass and size. For example, Jupiter has a much stronger gravitational pull than Earth because it is significantly more massive. Which of the following comparisons about gravitational pull is correct?

• Mars has a stronger gravitational pull than Earth because it is closer to the Sun.

• Mercury has a weaker gravitational pull than Earth because it is less massive

• Neptune's gravitational pull is weaker than Earth's because it is farther from the Sun.

• Venus has a stronger gravitational pull than Jupiter because it is closer to Earth in size.

Gravitational pull varies from planet to planet depending on their mass and size. Which of the following statements correctly explains a planet's gravitational pull?

• Jupiter has the strongest gravitational pull in the solar system because it is the most massive planet.

• Mars has a stronger gravitational pull than Earth because it has a larger diameter.

• The Moon has a stronger gravitational pull than Mercury because it is closer to the Earth.

• Saturn has a weaker gravitational pull than Venus because it is made mostly of gas.

The planets in our solar system take different amounts of time to complete one revolution around the Sun. Which of the following statements correctly compares the revolution periods of Earth and Mars?

• Mars has a shorter period of revolution than Earth because it is closer to the Sun.

• Mars has a longer period of revolution than Earth because it is farther from the Sun.

• Mars has a shorter period of revolution than Earth due to its larger size.

• Mars has a shorter period of revolution than Earth because it rotates faster.

The time it takes for a planet to complete one revolution around the Sun is called its orbital period. Which of the following statements correctly compares the orbital periods of Earth and Jupiter?

• Jupiter has a shorter orbital period than Earth because it is closer to the Sun.

• Jupiter has a longer orbital period than Earth because it is farther from the Sun.

• Jupiter has a shorter orbital period than Earth because it has a larger mass.

• Jupiter has the same orbital period as Earth because it has more moons.

Earth is the only planet in the solar system known to support life. Which of the following factors is most responsible for making Earth capable of sustaining life?

• Earth has a thick atmosphere made primarily of hydrogen.

• Earth has a strong magnetic field that prevents all forms of radiation from reaching the surface.

• Earth is located at just the right distance from the Sun to maintain liquid water.

• Earth rotates on its axis in a way that prevents extreme temperatures between day and night.

Earth's atmosphere plays a vital role in sustaining life. Which of the following is the most important function of Earth's atmosphere for supporting life?

• The atmosphere blocks harmful radiation from the Sun, preventing damage to living organisms.

• The atmosphere is composed mostly of carbon dioxide, which helps plants grow.

• The atmosphere contains high levels of methane, which warms the planet.

• The atmosphere allows all sunlight to reach the surface, ensuring constant warmth.

Which of the following statements best describes the relationship between a planet's distance from the Sun and its orbital speed?

• Planets closer to the Sun travel slower in their orbits compared to planets farther from the Sun.

• Planets farther from the Sun travel faster in their orbits than planets closer to the Sun.

• Planets closer to the Sun travel faster in their orbits compared to planets farther from the Sun

• The orbital speed of a planet does not depend on its distance from the Sun.

Which graph best represents the relationship between a planet's average distance from the Sun and the time it takes for the planet to revolve around the Sun?

• A straight line with a positive slope.

• A curve where the orbital period increases as the distance from the Sun increases.

• A curve where the orbital period decreases as the distance from the Sun increases

• A straight line with a negative slope.
