planetesemals
the Sun
According to the big bang theory, which statement is accurate about how the universe came to be?
Atoms such as hydrogen were destroyed.
Stars and galaxies formed.
It gradually warmed.
It expanded slowly.
Which statement accurately describes the inner planets?
Uranus is one of the inner planets.
The inner planets formed when the solar system cooled.
The inner planets are also called terrestrial planets.
The inner planets are larger than the outer planets.
A student came late to class and started her notes midway through the lecture. These are the notes she copied:
–Small, rocky object
–Not round, irregular shapes
–Several meters to kilometers
–Make up a belt between Mars and Jupiter
What should she title her notes?
Comets
Asteroids
Meteors
Meteoroids
Jeremy is late to science class and misses the very beginning of notes for the day. These are Jeremy's notes:
–Round objects that orbit the Sun
–Not large enough to have enough gravitational pull to clear the path of their orbit
–4 known in the Kuiper Belt (Eris, Haumea, Makemake, and Pluto)
–1 in the asteroid belt (Ceres)
Jeremy later copied the title of the notes from a friend. What title did Jeremy most likely copy?
Comets
The Kuiper Belt
Asteroids
Dwarf Planets
Which two scientists’ theories supported the general consensus of the people and religious teachings of the time?
Aristotle and Ptolemy
Ptolemy and Copernicus
Aristarchus and Aristotle
Galileo and Aristarchus
Which statement best describes the primary difference between scientific investigation and technological design?
Scientific investigation is more time consuming than technological design.
Technological design is more expensive than scientific investigation.
Technological design involves background research, and scientific investigation does not require research.
Scientific investigation involves experiments, and technological design involves products.
In which layer of the sun do sunspots occur?
Core
Corona
Photosphere
Convection Zone
What can be observed only by observing its effects on gravity?
solar nebula
gas and dust
planetesemals
dark matter
What will a medium-mass star become at the very end of its life cycle?
a red giant
a black hole
a white dwarf
a neutron star
Why was Copernicus’s heliocentric model not believed until Galileo and Kepler provided more evidence?
The model had the moon orbiting Earth.
The model was against religious teachings of the time.
The model could not explain retrograde motion.
The model did not include all eight planets in the solar system.
Look at the image of the solar system. W, X, Y, and Z represent (unnamed) objects in the solar system. Which one represents a gaseous giant?
W
X
Y
Z
Which statement accurately describes a light-year?
It is the shape of a galaxy.
It is the distance that light travels in a year.
It is a yearly measurement of light given off by stars.
It is the amount of time it takes light to travel one million kilometers.
Tanner has found a table of the atmospheric layers of the Sun. However, he can’t make out the names of the layers in the chart.
What are the names of the Sun's layers described in columns A, B, and C?
A: Corona; B: Photosphere; C: Chromosphere
A: Core; B: Chromosphere; C: Photosphere
A: Chromosphere; B: Corona; C: Core
A: Photosphere; B: Chromosphere; C: Corona
Which process describes how the sun produces fuel for itself?
the big bang theory
nuclear fusion
solar flares
heliocentric model
What happens first?
Most of the gas was pulled toward the center.
The solar nebula flattened into a rotating disk.
The solar nebula spun faster and faster.
It became hot and dense, and formed the Sun

(a) is the largest planet, revolves slowly around the Sun, has rings, 53 moons, and is known for its Great Red Spot
(a) rotates the opposite direction of the other planets, has a faster revolution than rotation, and is known as "Earth's twin"
(a) is blue in color due to the methane it contained in its atmosphere, has thin flat rings, and has a tilted axis.
(a) is the only planet with liquid water on the surface and an oxygen-rich surface.
(a) has no moons, is mostly dense iron at the center, has major temperature ranges, and has the shortest orbit around the sun.
(a) is the farthest terrestrial planet and is red in color due to high volumes of iron oxide on the surface.
(a) has the largest and most visible rings, a thick atmosphere of hydrogen and helium, has 62 moons.
(a) is one of the two "ice giants", is blue in color, gaseous, and has 14 moons.

What is the difference in a planet's ROTATION and its REVOLUTION?
Rotation is the path around the sun and revolution is the spin on its axis
Revolution is the path around the sun and rotation is the spin on its axis
Rotation is the path around the earth and revolution is the spin on the sun's axis
Revolution is the path around the earth and rotation is the spin on the sun's axis
