What does the Nebular Hypothesis suggest about the formation of the solar system?

• It was formed from a giant explosion.

• It was formed from a dense cloud of gas and dust.

• It was formed from a passing star.

• It was formed from a black hole.

Why do terrestrial planets form closer to the Sun, according to the Nebular Hypothesis?

• The Sun’s gravity is stronger closer to it.

• The heat from the Sun evaporated lighter elements, leaving behind heavier materials.

• There is more matter closer to the Sun.

• The Sun’s magnetic field is stronger closer to it.

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

What is the main evidence for the Nebular Hypothesis according to the text?

• The observation of star systems through microscopes

• The observation of similar processes happening elsewhere in the galaxy

• The observation of planets moving in their orbits

• The observation of galaxies through radio telescopes

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

What force acted on the massive nebula to collapse it and eventually form our sun?

• electrostatic force

• strong force

•  weak force

• gravity
