Order of Stages
A stable solar system is this stage in the nebular hypothesis.
Stage 6
This main event is the descriptor for stage 1 of the nebular hypothesis.
A nebula collapses inward.
A cloud of gas and dust.
Nebula
These components are what the solar system is formed from.
Gas and dust
Proto-
Protostar formation is this stage in the nebular hypothesis.
Stage 3
The main events in stage 5 of the nebular hypothesis.
Protoplanets pull in debris and grow inside. Moons form from the leftover debris.
The beginnings of a star.
Protostar
True or false: the Nebular Hypothesis is the only acceptable theory of the origins of the solar system.
False
A term describing the curved motion of one celestial (space) body around star or larger body.
Orbit
Nebula formation is this stage in the nebular hypothesis.
Stage 1
The main events in stage 4 of the nebular hypothesis.
Extra material forms a rotating disk around the protostar and the extra material begins to form tiny planets.
The beginnings of a planet.
Protoplanet
This is the event that triggers the start of the solar system's formation.
A nearby supernova explosion
The shape of the planets' orbits around the sun.
Elliptical (oval shaped)
Collapse and rotation is this stage in the nebular hypothesis.
Stage 2
The main events in stage 4 of the nebular hypothesis.
Gravity pulls the nebula inward while the cloud flattens and spins, increasing speed.
The force, dependent on mass, that one body exerts on another.
Gravity
The nebular hypothesis describes this.
The stages of formation from a nebula to a solar system
The galaxy our solar system is found in.
The Milky Way
Planetary disk and formation of the moon and planets are these two stages in the nebular hypothesis.
Stages 4 and 5
The main events in stage 3 of the nebular hypothesis.
Gas and dust gather at the center to create a protostar. Temperature and pressure rise in the process. Nuclear fusion begins.
A star that is exploding at the end of its life.
Supernova
The force that causes the nebula to continue to pull in towards itself.
Gravity
The main events of stage 6 of the nebular hypothesis.
