Planets: 1 point

•What are the three criteria to earn the name planet?

Answer Planets:1

• Orbits a star•Massive enough for gravity to

give it a nearly round shape.• Has cleared the neighborhood

around its orbit.

Planets: 2

• Identify each of the eight planets as either terrestrial or jovian.

Answer Planets: 2

• Terrestrial: Mercury, Venus, Earth, & Mars• Jovian: Jupiter, Saturn, Uranus,

& Neptune

Planets: 3

•What are the characteristics of a terrestrial planet?

Answer Planets: 3

• Slow Rotation• Rocky, Solid Surfaces • No Rings • Small w/high density• Few or no moons• Nearly circular orbits close to the sun

Planets: 4

•What are the characteristics of a jovian planet?

Answer Planets: 4

• Rapid rotation• Thick gaseous atmospheres with liquid

interiors• Rings• Large w/Low densities• Many moons• Nearly circular orbits far from the Sun

Planets: 5

• What is the largest planet in our solar system, 5th from the sun, and has a large “Red Spot” where there is an ongoing storm?

Answer Planets: 5

• Jupiter

Stars: 1

• How would you describe the size of our sun compared to other stars?

Answer Stars: 1pt

• Average size

Stars: 2pt

• 98% of the Sun’s mass comes from which elements?

Answer Stars: 2pt

• Hydrogen and Helium

Stars: 3pt

• What is the source of energy for the Sun and other stars?

Answer Stars: 3pt

• Nuclear Fusion

Stars: 4pt

• The Doppler shift of an object coming toward us is called a . The Doppler shift of an object moving away from us is called a

.

Answer Stars: 4pt

• Toward us is called a blueshift.• Away from us is called a redshift.

Stars: 5pt

• A star like our Sun will become a , when it reaches the end of its life cycle.

Answer Stars: 5pt

•White dwarf

Universe: 1pt

• A flash of light caused when a particle from space burns up in our atmosphere is a

.

Answer Universe: 1pt

•Meteor

Universe: 2pt

• A relatively small, icy object that orbits a star is a .

Answer Universe: 2pt

• Comet

Universe: 3pt

• Any object orbiting another object is a .

Answer Universe: 3pt

• Satelite

Universe: 4pt

• Where is the asteroid belt located?

Answer Universe: 4pt

• Between Mars and Jupiter, which is between the terrestrial and jovian planets.

Universe: 5pt

• A theory that best explains the beginning of our universe is .

Answer Universe: 5pt

• The Big Bang Theory

Solar System: 1pt

• What is an Astronomical Unit (AU)? How many km=1AU?

Answer Solar System: 1pt

• The average distance between Earth and the Sun, which is about 150 million km.

Solar System: 2pt

• Where does our solar system’s main source of energy come from?

Answer Solar System: 2pt

• The Sun

Solar System: 3pt

• List the planets in our solar system in their order from the Sun (closest to farthest away).

Answer Solar System: 3pt

• Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune

Solar System: 4pt

• What evidence is there to support the Sun being the center of our solar system?

Answer Solar System: 4pt

• Planets orbiting the Sun.• Correlation between

weather/climate on planets and their distance from the Sun.• Gravity from the Sun causes planet

rotation.

Solar System: 5pt

• What characteristics disqualify Pluto from being a planet?

Answer Solar System: 5pt

• Size, irregular orbit, and surrounding neighborhood not cleared of debris.

Movement: 1pt

• What is the definition of rotation?

Answer Movement: 1pt

• The spinning of an object around its axis.

Movement: 2pt

• What is the definition of a revolution?

Answer Movement:2pt

• The orbital motion of one object around another.

Movement: 3pt

• What causes day and night?

Answer Movement: 3pt

• Day and night is caused by the rotation of the Earth about its axis. At any given time, the half facing the Sun will be shined upon while the other half will have no light.

Movement: 4pt

• What is Earth’s rotational period? What does this mean?

Answer Movement: 4pt

• 24 hours• This means that it takes Earth 24

hours to make one rotation.

Movement: 5pt

• What causes Earth to have seasons?

Answer Movement: 5pt

• The tilt of Earth’s axis remains pointed in the same direction in space throughout the year. As a result, the orientation of the axis relative to the Sun changes over the course of each orbit.

• The Northern Hemisphere is tipped toward the Sun in June and away from the Sun in December.
