ESS Unit 3: Creation of Solar System Test

What does the 'nebula' refer to in the formation of the solar system?

• A cloud of hot gas and dust
• An explosion of a nearby supernova
• A spinning disc of gas and dust
• All of the above

What are 'planetesimals'?

• Large planets that formed early on
• Clumps of gas and dust that formed larger objects
• Orbits of the planets around the sun
• Shock waves from the supernova

What are 'protoplanets'?

• Smaller objects that collided to form larger planets
• Circular trajectories of planets around the sun
• Early stages of a planet's formation
• All of the above

What two factors did the position of the planets affect?

• Size and composition of the planets
• Length of the planets' rotations and revolutions
• Density and atmospheric composition of the planets
• All of the above

What happened to the outer planets because they were beyond the 'freeze line'?

• They became much larger and made of gas
• They remained smaller and more rocky in composition
• They had shorter orbital periods around the sun
• They developed thicker atmospheres

What happened at the end of planetary accretion?

• The planets reached their final positions in the solar system
• All the remaining material was swept up into the planets
• The process largely ceased due to lack of material
• All of the above

What are 'asteroids'?

• Balls of frozen gas that orbit the sun
• Small rocky bodies that orbit the sun
• Streaks of light that enter Earth's atmosphere
• Large gaseous planets in the outer solar system

What are 'comets'?

• Small rocky bodies that orbit the sun
• Cosmic snowballs of frozen gases, rock, and dust
• Streaks of light that enter Earth's atmosphere
• Moons that orbit the planets

What are 'meteors'?

• Small bodies of matter that enter Earth's atmosphere
• Moons that orbit the planets
• Asteroids that collide with each other
• Celestial objects that orbit the sun

Where is the 'asteroid belt' located?

• Between Mars and Jupiter
• Beyond the orbit of Neptune
• Surrounding the sun in the center of the solar system
• Within the orbit of Mercury
