Answer:
5. How are the gas giants similar?
<u><em>Since they are so massive, the gas giants exert a much stronger gravitational force than the terrestrial planets</em></u>.
6. What are some of the ways that the gas giants differ from the
planets closest to the sun?
<u><em>The outer gas giants are so large today because of how quick they were to accrete material, once an object gets massive enough it attracts others through gravity, making the process much quicker than granules sticking together through electromagnetic forces or random collisions. The reason the outer planets were able to get massive much quicker than the inner planets is that there is more material with larger circumferences and that material was able to stay a solid rather than become gaseous.</em></u>
How is Pluto different from both Earth and Saturn?
<u><em>Pluto is a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. The difference is Size and Distance.</em></u>
8. What are the main characteristics of asteroids?
<u><em>diameter. The surfaces of most asteroids are thought to be covered in dust. Asteroids formed much closer to the Sun, where it was too warm for ices to remain solid.</em></u>
