Describe the location and movement of the Kuiper Belt in relation to the rest of the solar system.

• It is located between Mars and Jupiter and moves in a circular orbit.

• It is located beyond Neptune and contains objects that move in elliptical orbits.

• It is located between Earth and Mars and moves in a spiral orbit.

• It is located within the asteroid belt and moves in a linear path.

Explain how gravity affects the motion of planets in the solar system.

• Gravity causes planets to move in straight lines away from the Sun.

• Gravity keeps planets in orbit around the Sun by pulling them towards it.

• Gravity has no effect on the motion of planets.

• Gravity causes planets to spin on their axes.

Analyze why Earth is able to support life, focusing on its proximity to the Sun.

• Earth is too far from the Sun, making it too cold for life.

• Earth is in the habitable zone, where temperatures allow liquid water to exist.

• Earth is too close to the Sun, making it too hot for life.

• Earth is in the asteroid belt, which provides necessary minerals for life.

Strategically plan a mission to study the Oort Cloud. What challenges would you need to consider?

• The Oort Cloud is too close to the Sun, causing extreme heat.

• The Oort Cloud is far from the Sun, requiring long travel times and communication delays.

• The Oort Cloud is within the asteroid belt, making navigation difficult.

• The Oort Cloud is located on Earth, making it easily accessible.

Evaluate the role of gravity in the formation of the asteroid belt.

• Gravity caused the asteroids to form a planet.

• Gravity prevented the asteroids from forming a planet, keeping them in a belt.

• Gravity has no effect on the asteroid belt.

• Gravity caused the asteroids to move away from the Sun.

Discuss the physical properties of terrestrial planets and how they differ from gas giants.

• Terrestrial planets are composed mostly of gases, while gas giants are rocky.

• Terrestrial planets have solid surfaces, while gas giants are composed mostly of gases.

• Terrestrial planets are larger than gas giants.

• Terrestrial planets have rings, while gas giants do not.

Analyze the importance of water presence on Earth for supporting life.

• Water is not necessary for life on Earth.

• Water is essential for chemical reactions that sustain life.

• Water is only important for cooling the planet.

• Water is only found in the atmosphere and has no role in life.

Describe the role of the Sun's gravity in the motion of comets within the solar system.

• The Sun's gravity repels comets, pushing them out of the solar system.

• The Sun's gravity attracts comets, causing them to orbit in elongated paths.

• The Sun's gravity has no effect on comets.

• The Sun's gravity causes comets to move in circular orbits.
