- 1. Multiple Choice
According to the Big Bang Theory, which graph best represents the relationship between time and the size of the universe from the beginning of the universe to the present?Size decreasing as time increasesSize and time both increasingSize does not change as time increasesSize increases, then decreases as time increases - 2. Multiple ChoiceWhich of the following is evidence of the Big Bang Theory?Cavemen heard a loud bang at the beginning of time.The universe isn't movingThe universe is expandingThe universe is getting smaller
- 3. Multiple ChoiceWhich of the following is NOT evidence of the Big Bang Theory?Abundance of Hydrogen and HeliumCMBR everywhereStars that are blue shiftedthe universe is getting bigger
- 4. Multiple ChoiceWhat is the CMBRThe shape of the universeThe first primordial elementsRed shifted galaxiesLeftover heat from the Big Bang
- 5. Multiple ChoiceWhat shape do scientists think the universe is?SphereTriangularSaddle ShapedFlat
- 6. Multiple ChoiceWhat is the percentage of Hydrogen in the Universe?0.10%8%91.90%100%
- 7. Multiple ChoiceWhich of the following statements best summarizes the presence of matter in the universe?There are more metal elements in the universe than nonmetals.All elements exist in an equal amount throughout the universe.There are more heavy elements than light elements.There are more light elements than heavy elements.
- 8. Multiple ChoiceHow did the discovery of Cosmic Microwave Background Radiation support the Big Bang Theory?It suggests that Hydrogen and Helium were the first elements to form.It confirms the age of the Earth to be around 5 billion years old.It supports the idea that the universe used to be hotter.It demonstrates that the universe continues to expand.
- 9. Multiple ChoiceWhich statement best describes the age of our solar system and universe?Our solar system and the universe are estimated to be 5 billion years old.Our solar system and the universe are estimated to be 10 billion years old.Our solar system is at least twice as old as the universe.The universe is roughly 13.7 billion years old.
- 10. Multiple ChoiceWhich of the following is NOT true about the Big Bang Theory?It is the scientific explanation of how life began on Earth and evolved over time.It is the scientific explanation for the origin of the universe.It states that the universe expanded from a single point and is still expanding today.It states that the universe used to be much hotter and smaller.
- 11. Multiple ChoiceWhat can we conclude from the observation that nearly all galaxies are moving away from us?Massive black holes are drawing galaxies away from Earth.The Sun and Earth are located at the center of the universe.Everything in the universe is moving the same direction.The once-smaller universe is expanding in all directions.
- 12. Multiple ChoiceWhich of the following best describes the expansion of the universe?As space expands, matter spreads out to fill up the empty space.Expansion involves the spreading of matter into infinite and empty space.As space expands the empty space between matter increases.As space expands, matter continually is created to fill that space.
- 13. Multiple ChoiceWhich of the following is the best description of the Big Bang Theory?The Big Bang Theory is the prevailing model about the universe’s origin and is supported by observations of the universe’s expansion.The Big Bang Theory is just one of the ideas about the universe’s origin, many of which are equally respected by the scientific community.The Big Bang Theory states that pre-existing matter was compacted into a hot and dense form and suddenly exploded into infinite, empty space.The Big Bang Theory is the scientific explanation of how the Sun, Earth, and the rest of the Solar System were formed at the beginning of time.
- 14. Multiple ChoiceWhich of the following is not strong evidence supporting the Big Bang Theory?Presence of cosmic microwave background radiation.The frequency of the light from distant galaxies is shifted slightly towards the redThe estimated age of the Earth matches the estimated age of the universe.Abundance of Hydrogen and Helium in the universe.
- 15. Multiple ChoiceAs part of the modern theory of the origins of the elements, it is hypothesized that before the formation of the stars, most of the matter in the universe consisted of what atoms?hydrogen and heliumnitrogen and carbonsilicon and lithiumuranium and radium
- 16. Multiple ChoiceWhy do red-shifted light spectrums from neighboring galaxies indicate the universe is expanding?Red light has the shortest wavelength on the visible light spectrumRed light has the longest wavelength on the visible light spectrumRed light has both long and short wavelengths on the visible light spectrumRed light has neither long, not short wavelengths on the visible light spectrum
- 17. Multiple ChoiceAt what temperature, following the Big Bang, was it cool enough for atoms to form?3000K3K10^10K10^28K
- 18. Multiple ChoiceThe temperature of the CMBR today is approximately....3000K3K10^10K10^28K
- 19. Multiple ChoiceWhy is the abundance of H/He throughout galaxies an important piece of evidence supporting the Big Bang?H/He were two of the first elements to form following the Big Bang.H/He are highly reactive generating hot spots.H/He are high mass elements formed from supernovae.All the above
- 20. Multiple ChoiceWhat do the color changes on the CMBR map represent?Density & Temperature ChangesLight & Distance ChangesBoth Density & Temperature and Light & Distance ChangesNeither Density & Temperature and Light & Distance Changes
