What is the FIRST event in the formation of the solar system?
About 4.5 billion years ago pieces of rock and ice accumulate more material until they grow into planets and moons.
About 4.6 billion years ago, a cloud of stellar dust or nebula exists within the Milky Way.
None of the above.
The planets of the solar system formed as
the center of the gas cloud cooled
planetesimals flattened into a rotating disk
planetesimals collided into one another
the sun absorbed extra gas and dust from the solar system
What force acted on the massive nebula to collapse it and eventually form our sun?
electrostatic force
nuclear fusion
the force from Star Wars
gravity
As the solar system continued to evolve, material in the disk collided with other material and grew into planetesimals, then protoplanets, and then planets. This process of growth by collision created a lot of heat, melting the early Earth. Growth by collision is called ___.
differentiation
accretion
adsorption
