AST101 CLICKER QUIZES UOFT QUESTIONS WITH
VERIFIED ANSWERS
What does the term "Solar System" mean? - Answers - The Sun, the planets, and all of
their moons
What does the term "Universe" mean? - Answers - The totality of all space, time,
energy, and matter
Earth is 1 AU from the Sun. What is the maximumpossible separation between Earth
and Mars? (Hint: Mars is the next farthest planet from the Sun) - Answers - 2.5 AU
A 'light year' is a measure of: - Answers - distance
Stars are... - Answers - balls of plasma which produce energy by nuclear fusion.
Planets are.. - Answers - rocky, icy, or gassy, and they don't produce much energy.
Why is Pluto no longer considered a planet? - Answers - Its orbit is full of other stuff
Definition of the term "planet" - Answers - Planets must have cleared their orbits. That
is, there can't be a lot of other stuff orbiting the parent star in orbits very similar to the
planet.
A moon is ... - Answers - any large body which orbits a planet.
Titan is a rocky/icy object with an atmosphere and liquid on its surface. It is spherical in
shape, has a clear orbit, and orbits Saturn. Titan is a ... - Answers - moon
Ceres orbits the Sun in the asteroid belt between Mars and Jupiter. It is large enough to
be spherical. Ceres is a... - Answers - dwarf planet
A solar system consists of ... - Answers - a star orbited by planets, moons, and lots of
debris (comets, asteroids, dust)
The Inner Solar System... - Answers - Mercury, Venus, Earth, Mars
The Outer Solar System... - Answers - :Jupiter, Saturn, Uranus, Neptune, many dwarf
planets & comets
How many stars are there in our Solar System? - Answers - one, the sun
The terrestrial planets are called - Answers - Mercury, Venus, Earth, Mars
, The terrestrial planets are - Answers - Rocky, relatively small, close to Sun
The jovian planets are called - Answers - Jupiter, Saturn, Uranus, Neptune
The Jovian planets are - Answers - gaseous, larger, and farther away from the Sun
Compared to planets in the inner Solar System, planets in the outer Solar System
generally - Answers - are made of lighter elements
What is it like on Mercury - Answers - No atmosphere, highly cratered surface, Rocky
exterior with a huge iron core
What is it like on Venus - Answers - Thick CO2 atmosphere, lots of (possibly) active
volcanoes. About the same size as Earth, Runaway greenhouse effect makes it even
hotter than Mercury, Rains acid, No moons
What is it like on Earth - Answers - Wet planet, Unusually big moon•Surface and
atmosphere heavily modified by life
What is it like on Mars - Answers - Very thin CO2 atmosphere•Many huge, extinct
volcanoes, Was probably warmer and wetter in the past, Many surface features
probably carved by water, No life known to date
The planet with the highest average surface temperature is... - Answers - Venus
Scientists announce the discovery of a new planet in another solar system. The planet
is the same size as Earth and orbits a star just like the Sun at a distance of 0.9 AU.
Based on our own solar system, what can we conclude about this planet? - Answers - It
will be made mainly of rock.
The asteroid belt is - Answers - A zone where rocky chunks orbit the sun between the
orbits of Mars and Jupiter.
What is it like on Jupiter - Answers - Largest planet in the solar system, Thick gaseous
atmosphere surrounds a giant ball of liquid hydrogen, and has very faint rings
What is it like on Saturn - Answers - Spectacular rings, More than 60 known moons
if you tried to land a space ship on a Jovian Planet, what would happen first? - Answers
- You'd be crushed by the tremendous gas pressure.
What is it like on Uranus and Neptune - Answers - ice giants, Both about the same size,
Both bluey/green, Both have many moons, Both have faint rings
