What initially triggers the collapse of a molecular cloud according to the Nebular Theory?

• A nearby supernova explosion

• Disrupted gravitational stability due to regions of different density

• Impact with another nebula

• Radiation pressure from nearby stars

What is the result of angular momentum in a collapsing molecular cloud?

• The cloud disperses into space

• The cloud remains static

• The cloud spins into a disk

• The cloud expands uniformly

According to the Nebular Theory, what are planetesimals?

• Small asteroids outside the solar system

• Clumps of matter in the protoplanetary disk

• Gases in the nebula

• Stars forming near the solar system

How do temperature gradients in the solar nebula influence the composition of planets?

• They have no significant effect

• They cause all planets to have similar compositions

• They result in different types of planets forming at varying distances from the Sun

• They prevent the formation of gas giants

What primarily differentiates Gas Giant planets like Jupiter and Saturn from Terrestrial planets like Earth?

• Gas Giants are closer to the Sun

• Gas Giants are primarily made of gases and ice

• Terrestrial planets are larger than Gas Giants

• Terrestrial planets have very little atmosphere

What is the Kuiper Belt?

• A region inside the orbit of Neptune rich in rocky planets

• A spherical region surrounding the solar system filled with gases

• A region of the solar system beyond the orbit of Neptune, believed to contain many comets, asteroids, and other small bodies made largely of ice

• The innermost region of the solar system containing the sun and terrestrial planets

Which event is theorized to have contributed to the formation of Earth's water?

• Jupiter losing water to the inner planets

• The formation of the Kuiper Belt

• The alignment of the Gas Giants

• Comets and planetesimals from the outer solar system hitting Earth during the Late Heavy Bombardment

What is the role of gravity in the formation of the solar system?

• Gravity repelled the initial particles, dispersing them across the solar system

• Gravity played no significant role in solar system formation

• Gravity is the driving force in the formation of the solar system

• Gravity only affected the formation of terrestrial planets

What does the Oort Cloud primarily consist of?

• Rocky debris from asteroid collisions

• Gaseous emissions from ancient supernovae

• Billions of comets and other icy bodies

• Planetary rings discarded by Gas Giants
