Answers
1
Which of these choices
best
describes what is seen in this picture of the sun?
solar flare
prominence
sunspot
aurora
2
In which model of the solar system does the sun revolve around Earth?
Aristarchan model
heliocentric model
Copernican model
geocentric model
3
Which of these choices
best
identifies what the diagram shows?
geocentric view
location of comets
heliocentric view
galaxy that is nearest to Earth
4
How is rotation of the equator of the sun different from the rotation of the poles of the sun?
The equator rotates more slowly than the poles.
the sun doesn't rotate
The equator and the poles rotate at the same speed.
The equator rotates more rapidly than the poles.
5
Which describes an effect of centripetal force?
objects burn at very high temperatures
objects break apart in space
objects move in an elliptical path
objects move in a circular path
6
What is the name of the object that can be seen in the circled area of the sun?
prominence
solar flare
sunspots
gamma rays
7
What is the apparent shift in the position of an object when viewed from different locations?
axis of rotation
ellipse
parallax
parallax problem
8
A meteoroid is a...
small body of ice,rock,and dust with an elliptical orbit
shooting star
irregular shaped rocky object that orbits the sun
sand grained to boulder sized rocky body in space
9
Which configuration will result in the
greatest
gravitational force?
large mass close together
larger mass far apart
small masses far apart
small mass close together
10
People sometimes talk about seeing a “shooting star.” What do they actually see?
A meteoroid that burns up in Earth’s atmosphere
A comet that has come close enough to Earth
A meteoroid traveling through space
A star that is moving through the galaxy
11
The Sun is a...
satellite
moon
planet
star
12
In a convection current hot gases rise, then cool and...
begin nuclear fusion
rise more
sink back down
release energy as solar flares
13
Why is nuclear fusion possible only in the cores of stars?
Hydrogen exists only at the core of stars.
High temperatures and pressures only occur in the core
Hydrogen and helium nuclei require a lot of light tobond
E = mc2 only works in the cores of stars
14
Which of the following describes Kuiper Belt Objects?
often larger than some planets in the solar system
extremely hot
minor planet-sized objects that orbit the sun beyond Neptune
100 AU wide
15
Which statements best describes the characteristics of the terrestrial planets?
made up of gas and close to the sun
small, dense, with rocky surfaces
Large, planetaryrings, many moons
Rocky cores, close tothe sun, surface craters
16
Which layer of the sun is represented by #2?
chromosphere
photosphere
convective zone
radiative zone
17
Which term
best
describes the shape of the orbits of planets in our solar system?
centripetal
elliptical
circular
spherical
18
What is a gas giant?
A cloud in space made of gas and dust
A large, red supergiant star
A rock from space that reachesEarth’s surface w/o burning
A planet that has a deep, massive atmosphere
19
What is weight?
the measurement of the pull of gravity on an object
how heavy an object is
the volume of an object
the amount of matter an object contains
20
What is a meteorite?
a streak of light in Earth's atmosphere from a meteoroid
a small rocky object in space
a meteoroid that has reached Earth's surface w/o burning up
an icy, rocky, dusty space object with a tail
21
Which of the following keeps the planets in our solar system in orbit around the Sun?
electromagnetic energy
gravity
thermal energy
atmospheric pressure
22
What role did gravity play in forming the sun?
it caused small particles to collide to form the sun
it turned the protoplanetary disk into the sun
it caused a solar nebula to collapse creating the sun
it turned it into a planetesimal, which became the sun
23
Which of these objects is pictured in the diagram?
a comet
a meteorite
a meteor
an asteroid
24
Which would change if you took a trip to the moon?
both
neither
mass

25
Heat energy from the Sun is transferred to Earth primarily by which of the following processes?
radiation
conduction
convection
evaporation
26
Which is the innermost layer of the sun?
chromosphere
core
corona
convection zone
27
What is an irregular shaped body made of rock/organic material that is between Mars and Jupiter
a meteor
a comet
a meteorite
an asteroid
28
what is a meteor?
a meteoroid that has reached Earth's surface
a streak of light as a meteoroid burns in Earth's atmosphere
a small body of ice, rock, and dust in an elliptical orbit
