Solar System Flashcards
nebular hypothesis was proposed by who
Emmanuel Swedenborg
solar system emerged from a giant cloud of molecular gas and dust
collapse
an event upset the balance between the cloud’s internal heat and gravity
collapse
it caused the cloud to compress and collapse in on itself
collapse
rotated to conservation of momentum
spinning
size decreased due to conservation of momentum, thus spinning faster
spinning
began to assume a flat disk shape with a bulge at the center
flattening
matter aggregated towards the center of the disk, turning very dense and hot
flattening
in the cooler spaces far from the center, molecules began to condense into solid or liquid droplets
condensation and accretion
gave birth to the sun
condensation and accretion
that blew away the cloud’s leftover materials that didn’t form planets
condensation and accretion
the solar system was formed through five stages
nebular hypothesis
how the solar system originated from a close encounter or collision between the sun and another heavenly object
encounter hypothesis
materials formed a cloud of debris that was ____ in the middle portion and ___ at the end
thick - thin
began to orbit around the sun and eventually formed into planets
sun star encounter
succession of bolts was torn from the sun by the gravity of the passing star
planetesimal hypothesis
blots from the far side of the star went to where
nearer distances
bolts from the near side of the star went to where
farther distances
these bolts grew larger by gathering the
planetesimals, smaller, scattered bodies
incorporated components of nebular hypothesis
protoplanet hypothesis
_____ in the rotation of the nebula raised the whirlpools of gas in the _____
non uniformity - rotating mass
whirlpools of gas condensed into protoplanets
protoplanet hypothesis
did not explain adequately the chemical and physical differences of the planets
protoplanet hypothesis
he proved that the differences in chemical and physical composition because of temperature
