Which of the statements is not true about Saturn? (question 11)
It travels around the sun once every 29.5 years
It is composed mostly of hydrogen and helium gas
It is the only planet with a ring system
It has a large number of moons
4
Which of the following accurately relates which terrestrial planets have moons and how many moons they have?
Mercury and Venus (0), Earth (1), Mars (3)
Mercury and Venus (0), Earth (1), Mars (2)
Mercury, Venus, and Earth (1) and Mars (2)
Mercury and Venus (0), Earth (2), Mars (2)
5
What does Kepler's first law of planetary motion state?
the orbit of a planet is dependent on heat
the orbit of a planet around the sun is an ellipse with sun at one focus
the orbital period is infinite
the difference between centripedal force and elliptical force
6
Which describes an effect of centripedal force?
objects burn at very high temperatures
objects move in a circular path
objects move in an elliptical path
objects break apart in space
7
The solar system formed from a ________, which is a rotating cloud of gas and dust that formed into the sun and planets.
solar nebula
nuclear fusion
terrestrial planets
parallax
8
_____________ is the process in which energy is released as the nuclei of small atoms combine to form a larger nucleus.
parallax
terrestrial planets
nuclear fusion
solar nebula
9
A(n) ________ is a small, rocky object that orbits the sun.
terrestrial planets
gas giant planets
asteroid
solar system
10
Which of the following describes Kuiper Belt objects? (question 8)
extremely hot
often larger than some planets in the solar system
minor planet-sized objects that orbit the flat belt beyond Neptune's orbit
100 AU wide
11
meteoroid that reaches Earth's surface
meteoroid
meteor
meterorite
12
Which comet is in the closest orbit to the sun? (question 9)
Brant
Rasmussen
Schier
Zigler
13
Why is nuclear fusion possible in the cores of stars?
hydrogen exists only in the cores of stars
high temps and pressures required for fusion to occur, occur in the core
hydrogen and helium nuclei require a lot of light to bond together
E=MC2 only works in the cores of stars
14
What are sunspots?
a spot with a weaker magnetic field
a light area on the sun's corona that is hotter than surrounding areas
a spot easily seen without a telescope
a darker area on the photosphere that is cooler than surrounding areas
15

calculating mathematical models
observing the sun
assuming that all pre-existing astronomic theories were incorrect
using a telescope to see four moons orbiting Jupiter
