Test 2

Question 1

Starting from the shortest wavelengths and going to the longest wavelength name in order which kind of light comes first.

Answer 1

1. Gamma
2. X ray
3. Ultraviolet
4. Visible
5. Inferred
6. Microwaves
7. Radio

Question 2

Which combination of properties describes the most energetic kind of light wave?

Answer 2

Short wavelength and high frequency

Question 3

If we built a scale model of the solar system, where Neptune was one city block away from the Sun, then Neptune would b approximately what size to be the proper scale?

Answer 3

About the size of a pea

Question 4

How do orbit sizes of Jovian plants compare to those of terrestrial plants?

Answer 4

Jovian planets have a much bigger orbit size.

Question 5

How do the diameters of Jovian planets compare to terrestrial planets?

Answer 5

Jovian planets are much bigger in diameter than terrestrial.

Question 6

Of the following, which planet has the smallest diameter? 
A. Earth 
B. Jupiter
C. Uranus
D. Neptune

Answer 6

A. Earth

Question 7

The magnetic fields of Jovian planets are stronger than the magnetic fields of terrestrial planets. Explain why.

Answer 7

This is because of what they are made of, terrestrial planets are mostly made of rock while Jovian planets are made of liquids. Jovian planets are much more magnetic because of this.

Question 8

How do the average densities of Jovian planets compare to terrestrial planets.

Answer 8

?

Question 9

How do the average densities of Jovian planets compare to terrestrial planets?

Answer 9

The densities of Jovian planets tend to be less than that of terrestrial planets.

Question 10

Of the following solar system bodies, which should have highest density?
A. Saturn
B. Pluto
C. Europa 
D. Mercury

Answer 10

D. Mercury

Question 11

Explain how we use direct observations of the surfaces of planets to deduce what the outer layer of a planet is made of.

Answer 11

Look at the pattern of colors and wavelengths since all of these are unique to different materials.

Question 12

Direct observations of the surface of planets only tell us what the outer layers are made of light elements like hydrogen and helium?

Answer 12

Look at the average density of the plant to figure out what it is made of.

Question 13

What are the Galilean Satellites?

Answer 13

Europa, Ganymede, and Callisto

Question 14

Io is smaller in size to the Earth’s Moon. If we suddenly replaced Earth’s Moon with Io, the volcanoes on Io would probably eventually stop. Explain this.

Answer 14

This would happen because there would be much less gravitational pull on Io and that would in turn cause it to cool.

Question 15

The Galileo space probe detected a magnetic field generated by Ganymede. Based on this what is Ganymede likely to contain inside?

Answer 15

It is likely to contain water.

Question 16

Comet tails tend to point away from the Sun, why is this?

Answer 16

That is because the Sun tends to give off tangible particles that push the tails in the opposite direction.

Question 17

Explain what “planetary migration” says about the orbits of the Jovian planets.

Answer 17

Planetary migration states that there is a good chance that some of the Jovial planets started out closer to the Sun and slowly migrated out.
