Answers
1
How would the spectrum of the unknown element on the distant star be described?
blue shifted
offset
redshifted
reflected
2
What evidence does this star provide that supports the Big Bang theory?
it is giving off light and heat.
it is moving away from other objects in the universe.
it is moving towards other objects in the universe.
It fuses hydrogen and helium in the core to give off energy.
3
A small star with a short lifespan will produce what types of elements?
elements that are found on small planets
elements that are mostly gases
elements with smaller atomic weights
elements that have large atomic weights
4
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
It is widely accepted through stories by all cultures.
It cannot be changed unlike most other explanations
Relies on evidence from starlight and other radiation
5
What happens to the atoms of a star each time it goes through a life stage?
more atoms are formed
the atoms change places
the weight of atoms decreases
the atoms become heavier
6
What will the fusion of two helium atoms produce?
a berillium (Be) atom
a boron (B) atom
a lithium atom
a carbon (C ) atom
7
Which stars have the greatest red shift?
Stars in the nearest galaxy that are spinning
Stars closest to Earth where we can see them better.
Stars farthest from Earth with the greatest speed.
Stars nearest the Sun where light is more plentiful.
8
What evidence supports the nebular theory of solar system formation?
geologic evidence from the outer planets,Jupiter and Neptune
Measurements of the speed and brightness of distant stars.
direct observation ofcollapsing stars and matter around them
recent formation of new planets inside our solar system
9
How do stars produce larger and heavier atoms during their lifespan?
The atoms are attracted to each other electrically
The atoms bond together in chemical reactions.
The atoms fuse as the star goes through its life stages.
The atoms expand because they get hotter.
10
How did the inner planets gain matter?
When heat in their cores expanded them.
As atoms in the crusts unde rwent nuclear fusion.
Through the accretion or accumlation of matter from space
From the collision of one planet with another
11
How would the lightof the star be described by the observer at X?
red shifted
faster
shape shifter
brighter
12
What does much of the evidence for the Big Bang theory depend on?
reading and understanding past discoveries
observations of the big bang occurring in other galaxies.
understanding the data gathered with technology
accepting ideas you cannot understand
13
How does CosmicMicrowave Background Radiation support the Big Bang theory?
It is light that has traveled to the edge of the universe.
It is energy left behind from the Big Bang explosion
It is radiation in space that got moved out of the way
It is part of the theory that has never been explained.
14
Which is evidence supporting scientific explanation for heavy element formation?
tracing elements to see where they're from
samples of the matter in our Sun show what it's made of
traveling outside Earth shows stars look the same from space
supernova explosions that have been analyzed by scientists
15
Which factor allowed the inner terrestrial planets to be formed from denser, rockier material?
Higher temperatures
Greater speed
Less available matter
More gravity
16
People once thought the Earth was the center of the universe. Why did they think this was true
the planets were not visible to people then
they were not good at making observations
the sun and moon appear to go around Earth
the universe has changed since the early days
17
Which elements were formed in the big bang?
chlorine, argon
carbon, oxygen
nitrogen, carbon dioxide
hydrogen, helium
18
Which statement best describes how technology has helped us understand the solar system?
New technology allows the laws of the universe to change
Technology allows new types of data to be collected quickly.
New technology allows scientists to travel to other planets.
Technology makes scientists limit their observations.
19
Why do scientists accept the Big Bang theory?
it seems to make sense
they trust other scientists
evidence supports it
it is a belief based on faith
20
How do meteorites that fall to Earth support the nebular theory?
They are the same shape as Earth and the planets.
Meteorites have evidence of erosional processes on planets
The meteorites are made from the different elements
The meteorites are the same age and composition as Earth
21
Which of the following would be the best model of the “Big Bang” theory?
launching a rocket engine
dropping a bag of oranges off of a tall building
throwing a ball
lighting a firecracker
22
How did technology help Hubble make his discovery?
He was able to work on nights when the sky was clear
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.
23
How does the nebular theory describe the
formation
of the solar system?
A giant asteroid collision
A cloud of spinning dust and gas
A star exploded
Chunks of matter from the big bang were blasted into space
24
How would an astronomer explain the difference between the two spectra?
The star is moving away from us, lengthening the light waves
Light traveling through space is warped by the vacuum
The element gives off light differently if it is far away
The star is fusing a different kind of element than the sun
25
Bright new stars observed in the remains of exploded star systems are made from what?
from the elements produced by the exploded stars
from the energy of the exploded stars that has become matter
from the elements still remaining from the bigbang explosion
from empty space
26
How did the Big Bang start?
From a tiny point of pure energy.
Light waves condensed in a single area and matter formed.
Several galaxies collided and exploded.
The universe appeared in its current location
27
What has been happening to the matter in the universe since the Big Bang occurred?
Matter is contracting and coming back together again.
Matter has moved outward and collected into galaxies.
Matter has moved from one end of the universe to another.
Matter has been stable and unmoving ever since.
28
What does a star produce when it undergoes a “nova” or “supernova” explosion?
Huge quantities of hydrogen
Extremely small, energetic particles
All the heavier atoms found in the universe
Mostly uranium and other radioactive elements
29
Where did the heavy elements that make up Earth come from?
colliding asteroids
evaporating comets
super novas
other planets
30
What does this story show about the development of scientific theory?
New technology can lead to new discoveries.
Scientific discoveries are rarely rewarded
Scientists compete with one another and rarely cooperate
Accidents almost always happen in science
31
All the elements found on Earth were
formed
where?
in the Sun
in the gas cloud that formed Earth
in Earth’s core
in ancient stars
32
What will the fusion of two hydrogen (H) atoms produce?
one lithium (Li) atom
one helium atom
one half of a helium (He)atom
two helium atoms
33
How does light from stars support the Big Bang Theory? It shows that
the light from objects in space is “blue shifted”
the universe is collapsing again
most objects in space are moving away from one another
the Big Bang happened slowly over millions of years
34
Galileo went to jail for publishing evidence that supported the Heliocentric theory. Why?
Scientists have often been sent to jail for new ideas.
Did not follow the correct steps to have his work approved
His ideas opposed the cultural and religious practices.
It appeared he had illegally stolen the work of others.
35
Which of the following is supported by evidence from red-shifted starlight?
Objects in space are moving toward each other.
Objects in the universe are not moving.
Objects in space are moving away from each other.
Objects in space do not give off blue wavelengths.
