Unit 9 Intro (solar system formation)

What solar system models places the Sun at the center? 

• Geocentric Model
• Heliocentric Model
• Ptolemy Model
• Artistotle Model

Where did the materials used to create planets in our solar system come from? 

• clumps of rocky material between the stars

• they came from a cloud of gas that also created our sun

• they flung out of our young sun

• gas cloud in the orion nebula

Because of temperature in the protoplanetary disk...

• Rocks, metals and ices froze in the inner region only
• Rocks and metals froze in both regions and ice only in outer region
• Rocks and metals froze in the inner region and ice in outer region
• Rocks and metals froze in both regions and hydrogen gas froze only in outer region

The order of the formation of the solar system: 
Solar nebula - protostellar disk- nuclear fusion - sun - planetesimals - planets

• True
• False

Which object will hit the ground first? A 300 kg ball or a 30 kg ball. 

• The 30 kg ball
• The 300 kg ball
• Both hit at the same time
• It only works on the moon
