Answers

1
Which is evidence supporting scientific explanation for heavy element formation?
supernova explosions that have been analyzed by scientists
traveling outside Earth shows stars look the same from space
samples of the matter in our Sun show what it's made of
tracing elements to see where they're from
2
How did technology help Hubble make his discovery?
His work was published in the most recent scientific journal
He used telescopes that collected accurate data from space
He used cell phone technology that was ahead of its time.
He was able to work on nights when the sky was clear
3
What does this story show about the development of scientific theory?
Scientists compete with one another and rarely cooperate
New technology can lead to new discoveries.
Scientific discoveries are rarely rewarded
Accidents almost always happen in science
4
Which of the following is supported by evidence from red-shifted starlight?
Objects in the universe are not moving.
Objects in space are moving toward each other.
Objects in space are moving away from each other.
Objects in space do not give off blue wavelengths.
5
What evidence does this star provide that supports the Big Bang theory?
it is moving towards other objects in the universe.
it is moving away from other objects in the universe.
It fuses hydrogen and helium in the core to give off energy.
it is giving off light and heat.
6
How would an astronomer explain the difference between the two spectra?
The element gives off light differently if it is far away
The star is moving away from us, lengthening the light waves
Light traveling through space is warped by the vacuum
The star is fusing a different kind of element than the sun
7
Which stars have the greatest red shift?
Stars nearest the Sun where light is more plentiful.
Stars closest to Earth where we can see them better.
Stars farthest from Earth with the greatest speed.
Stars in the nearest galaxy that are spi
8
Why do scientists accept the Big Bang theory?
it is a belief based on faith
it seems to make sense
they trust other scientists
evidence supports it
9
Which statement best describes how technology has helped us understand the solar system?
New technology allows scientists to travel to other planets.
New technology allows the laws of the universe to change
Technology makes scientists limit their observations.
Technology allows new types of data to be collected quickly.
10
Where did the heavy elements that make up Earth come from?
evaporating comets
super novas
other planets
colliding asteroids
11
How does light from stars support the Big Bang Theory? It shows that
most objects in space aremoving away from one another
the Big Bang happenedslowly over millions of years
the light from objects in space is “blue shifted”
the universe is collapsing again
12
Which of the following would be the best model of the “Big Bang” theory?
dropping a bag of oranges off of a tall building
launching a rocket engine
throwing a ball
lighting a firecracker
13
Which elements were formed in the big bang?
carbon, oxygen
chlorine, argon
hydrogen, helium
nitrogen, carbon dioxide
14
What has been happening to the matter in the universe since the Big Bang occurred?
Matter has been stable and unmoving ever since.
Matter is contracting and coming back together again.
Matter has moved from one end of the universe to another.
Matter has moved outward and collected into galaxies.
15
How does CosmicMicrowave Background Radiation support the Big Bang theory?
It is part of the theory that has never been explained.
It is radiation in space that got moved out of the way
It is energy left behind from the Big Bang explosion
It is light that has traveled to the edge of the universe.
16
How do meteorites that fall to Earth support the nebular theory?
They are the same shape as Earth and the planets.
The meteorites are the same age and composition as Earth
The meteorites are made from the different elements
Meteorites have evidence of erosional processes on planets
17
What does much of the evidence for the Big Bang theory depend on?
observations of the big bang occurring in other galaxies.
reading and understanding past discoveries
understanding the data gathered with technology
accepting ideas you cannot understand
18
How did the Big Bang start?
The universe appeared in its current location
Several galaxies collided and exploded.
From a tiny point of pure energy.
Light waves condensed in a single area and matter formed.
19
People once thought the Earth was the center of the universe. Why did they think this was true
they were not good at making observations
the sun and moon appear to go around Earth
the universe has changed since the early days
the planets were not visible to people then
20
How would the spectrum of the unknown element on the distant star be described?
redshifted
blue shifted
reflected
offset
21
Cultures can explain the origin of the universe.The scientific explanation is different because
All scientists agree on it and no further research is needed
Relies on evidence from starlight and other radiation
It cannot be changed unlike most other explanations
It is widely accepted through stories by all cultures.
22
Bright new stars observed in the remains of exploded star systems are made from what?
from the elements still remaining from the bigbang explosion
from the elements produced by the exploded stars
from the energy of the exploded stars that has become matter
