The gravitational collapse of the solar nebula according to the nebular theory was triggered by:

• a nearby supernova explosion

• the cooling of the nebula over time

• the collision of two nebulae

• the formation of the Sun's core

Which statement about planetary impact craters in the early formation of the solar system is BEST supported by this theory?

• All planets likely experienced few collisions that resulted in impact craters.

• All planets likely experienced many collisions that resulted in impact craters.

• The Jovian planets formed before others, which led to more collisions and impact craters.

• The terrestrial planets formed before others, which led to fewer collisions and impact craters.

Select the THREE features of the solar system that are explained by the nebular theory.

• The planets all orbit the Sun in different planes.

• The center of the solar system contains the most heat and the most mass.

• The Jovian planets are made of the same elements as the Sun.

• The planets and asteroids all orbit the Sun in the same plane.

• The planets all orbit the Sun in the same direction.

Which characteristics of the solar system are BEST explained by the shape and motion of the flattened, spinning disc that came from the solar nebula?

• The disc shape of the flattened solar nebula explains the spherical shape of the planets. The spinning motion of the disc explains why all of the planets orbit the Sun in the same direction as the Sun’s rotation.

• The disc shape of the flattened solar nebula explains the spherical shape of the planets. The spinning motion of the disc explains why all of the planets orbit the Sun in the opposing direction as the Sun’s rotation.

• The flattened shape of the spinning disc explains why all of the planets lie in the same plane. The spinning motion of the disc explains why all of the planets orbit the Sun in the same direction as the Sun’s rotation.

• The flattened shape of the spinning disc explains why all of the planets lie in the same plane. The spinning motion of the disc explains why all of the planets orbit the Sun in the opposing direction as the Sun’s rotation.

How does the amount of hydrogen gas in a star change over its lifetime?

• It increases because hydrogen atoms are formed in a red giant when helium fuses.

• It decreases because hydrogen atoms become fused together to form helium atoms.

• It fluctuates up and down because the star performs different types of nuclear fusion at different life stages.

• It stays the same because hydrogen atoms are gained from space to replace the atoms lost during nuclear fusion.
