The Big Bang
Rapid expansion of the Universe from a single point.
The Big Bang
What is the 7th planet from the sun?
Uranus
What is a red giant?
Very large star that has high luminosity and low surface temperature.
What is the solar system?
All the objects that are held by the sun's gravity.
What is a Meteor?
Small pieces of matter that enter the Earth's atmosphere.
What is at least one evidence of the Big Band? Describe it!
Redshift (Show that the universe expands Inferred and Ultraviolet)
Abundance of Elements ( About 12 billion years to get the elements and the amount we have)
Age of stars (The oldest star is about 12 billion years old)
Hubble's Law (Hubble found a way to calculate the expansion of the universe)
Cosmic background radiation (Energy left over from the Big Bang)
What planet has 2 moons?
Mars
When the temperature is high enough what does helium fuse into?
heavier elements
How many planets are in the solar system?
8
What is a Meteoroid?
Small pieces of matter before they enter the Earth's atmosphere.
Anything that occupies space and has mass.
Matter
Which planet is the largest?
Jupiter
What is the inner layer of a Red giant made most fusing?
Helium
What is the Geocentric theory?
That the earth was believed to be the center of the universe.
What are Meteorites
Small pieces of matter that survives the Earth's atmosphere and hits the ground (water/land)
What is the first thing that happened after the Big Bang?
Hot and Dense
What are the inner 4 planets called?
Rocky
What is the outer layer of a Red giant made most fusing?
Hydrogen
What is the Heliocentric theory?
That the Earth and all other planets revolved around the sun.
Is it possible for the same object to be all three? Why or why not.
Yes, because all small pieces of matter start of as Meteoroid, then a meteor fi they enter Earth's atmosphere, and then a Meteorite if it hits Earth (Land/Water)
Contains all matter and energy that exists now, that existed in the past, and that will exist in the future?
Universe
What are the outer 4 planets called?
Gas giants
What happens when all the hydrogen is used up?
The star's core collapses inward and the cores temperature increases.
Who found the evidence saying that the Heliocentric theory? What was the evidence?
Galileo. He saw moons orbiting Jupiter.
What is a shooting star (falling star) categorize as?
Meteoroid Meteor or Meteorite
Meteor
