Answers
1
The most extreme high and low tides are called:
Diurnal Tides
Gravitational Tides
Spring Tides
Neap Tides
2
Which of the following differences between the inner and outer planets is true?
Inner are very dense, outer have low densities.
Inner have many moons, outer have very few moons.
Inner rotate slowly, outer rotate quickly.
Inner are gas, outer are terrestrial.
3
The name given to a region in space surrounding a star where its gravity is dominant is:
solar system
star cluster
asteroid belt
galaxy
4
Which of the following stars is the smallest?
Neutron Star
White Dwarf
Super Giant
Giant
5
What is the primary evidence that supports the Big Bang Theory?
Data collected from the universe's beginning.
The universe is expanding.
The universe is staying the same and not changing.
We've observed similar occurrences in parallel universes.
6
How do we know that black holes exist?
We can see the tear in space-time that black holes create.
We can see them directly with high powered telescopes.
We have sent probes into black holes to collect data.
We can see their gravitational influence on other objects.
7
Why does the moon stay in orbit?
The moon's inertia balances gravity pulling on the moon.
There's no gravity in space so it floats.
Gravity pulls it towards Earth's surface.
Inertia keeps it moving in a circular path.
8
The process used to determine the composition of stars is called:
spectroscopy
astrology
cosmology
radiography
9
Will a star like our sun form a black hole?
Yes because our sun is large enough to form a black hole.
No because the sun is not large enough to form a black hole.
Yes because black holes are formed whenever a star dies.
No because black holes are not formed from stars dying.
10
Which of the following is not a layer of the sun?
Corona
Asthenosphere
Chromosphere
Photosphere
11
How many planets are in our solar system?
9
8
7
10
12
What causes stars to shrink as they near the end of their life cycle?
The star "runs out of gas" and simply burns out.
Fusion stops and the star collapses under its own gravity.
Fusion continues and pushes gas outwards.
The star loses mass as it goes through fusion.
13
What separates the inner and outer planets?
Asteroid belt
Comet belt
Kuiper belt
Meteor belt
14
Large dark areas on the Moon's surface are called:
Highlands
Marias
Divets
Craters
15
What is the best evidence of the Giant Impact Theory?
Lunar rocks have a similar composition as rocks from Mars.
Moon is a similar density as Earth's crust/mantle.
Astronomers watched the Giant Impact occur.
There is no evidence of the Giant Impact Theory.
16
What is a black hole?
All of these are correct.
A rip in the space-time fabric.
A point of indefinite gravitational influence.
The end result of a massive star indefinitely collapsing.
17
Why is Pluto no longer considered a planet?
It has an irregular orbit.
It's too similar to other KBO's, asteroids, moons, etc.
It's too small.
All of these are true.
18
A giant cloud of dust and gas where stars are formed is called a:
star cluster
nebula
protostar
galaxy
19
What is the shape of most planets' orbits?
Highly elliptical
Perfectly circular
Slightly elliptical
Irregular
20
Why do we only see one side of the moon?
Earth's revolution around the sun keeps one side visible.
The moon changes its illumination gradually.
Gravitational locking keeps one side visible.
We can see both sides of the moon.
21
When astronauts go to the moon, their __________ changes.
mass and weight
neither mass or weight
mass
weight
22
Why is Venus the hottest planet in our solar system?
It's closest to the sun.
It's not the hottest planet; Mercury is.
Its atmosphere results in an unchecked greenhouse effect.
It doesn't rotate quickly enough.
23
A cooler, dark region on the sun's surface is a:
sunspot
solar wind
solar flare
prominence
24
The planet farthest from the sun is:
Pluto
Saturn
Neptune
Uranus
25
Why does a comet form a visible tail as it approaches the sun?
Increase in velocity
Increase in temperature
Solar flare
Solar wind
26
How does the sun produce energy?
Both Nuclear Fusion and Fission
Nuclear Fusion
Absorbing and Re-emitting Energy from Other Stars
Nuclear Fission
27
What determines the life span of a star?
Its mass
Its gravitational pull
Its diameter
Its chemical composition
28
The name of the largest crater on the moon visible from Earth is:
