Self-Check: Solar System Formation

What does the Solar Nebular Theory propose about the formation of the solar system?

• It indicates that planets were formed from the fission of a star.

• It states that planets formed from collisions of large bodies.

• It suggests that the solar system formed from a rotating cloud of gas and dust.

• It claims that the solar system was created by a supernova explosion.

Which of the following is a flaw of the Solar Nebular Theory?

• It overlooks the role of gravity in planet formation.

• It fails to describe the formation of protoplanets.

• It does not account for the angular momentum distribution.

• It cannot explain the presence of comets.

According to the Protoplanet Theory, how did the Sun and planets form?

• They formed from the same cloud of gas and dust.

• They were created from the remnants of a supernova.

• They originated from collisions of existing planets.

• They were formed by the gravitational collapse of a single star.

What is the main evidence supporting the Planetesimal Theory?

• The discovery of exoplanets.

• The presence of protoplanetary disks.

• The existence of black holes.

• The alignment of planets in the solar system.

What does Laplace's Nebular Theory suggest about the solar system's formation?

• It developed from the collision of multiple stars.

• It formed from a static cloud of gas.

• It originated from a rotating nebula that collapsed.

• It was created by a series of supernovae.

What is a characteristic of a protostar?

• It is fully formed and shines brightly.

• It is dimmer due to nuclear fusion.

• It is brighter than other stars.

• It is composed entirely of ice.

How do terrestrial planets form according to the theories discussed?

• By the fission of larger planets.

• From the gravitational collapse of gas clouds.

• By the collision and accumulation of planetesimals.

• Through the process of nuclear fusion.

What role does gravity play in the formation of the solar system?

• It causes planets to collide and break apart.

• It draws together gas and dust to form celestial bodies.

• It has no significant impact on formation.

• It prevents the formation of moons.

What is the significance of the frost line in the solar system's formation?

• It indicates where comets are formed.

• It separates rocky planets from gas giants.

• It marks the boundary of the solar nebula.

• It determines the size of the Sun.

What is the primary process by which protoplanets form?

• Fission of larger bodies.

• Accretion of planetesimals.

• Condensation of gases.

• Nuclear fusion.
