EARTH SCIENCE FINAL PREP
Because the Big Bang only produced Helium, Hydrogen and a couple of trace elements
Where did the oceans most directly come from after the earth cooled down a lot?
It’s carbon dioxide atmosphere lets sunlight in, but doesn’t let the heat back out
What causes the pressure in a star that causes it to begin its burning reaction?
If very humid warm air hits very cold humid air, what kind of weather is most likely to occur?
Left to Right • Dust & Gas • Planetesimals • Proto-planets • Planet
What is the force that causes particles in space to keep forming larger and larger clumps until they finally become a planet?
Heat from the sun radiates away from Mercury because it has no atmosphere. • Heat from the sun can’t escape Venus’ atmosphere because it is made of carbon dioxide
Why were the gas giants able to capture hydrogen when the inner planets were unable to capture hydrogen?
Near the sun, hydrogen and helium are warm and move too fast fro a planet to capture them. • Out near the gas giants it is very cold and the molecules slow down enough to be captured by the planets gravity
The temperature of a star can be determined by it’s color. What is the correct order of star colors from the coolest to the hottest?
Red Cool • Yellow Warmer • White Hot • Blue REAL HOT
