Which planet is not classified as an inner planets?
Mercury
Venus
Uranus
Earth
Which characteristics is not shared by all of the inner planets
little Hydrogen and Hellium
small diameters
mostly solid
large diameters
What caused the inner planets to develop like they did?
being near the Sun's heat left them with only rocky and metalic materials
being far from the Sun's heat allowed them to accumulate large amounts of volatiles
being in the Oort cloud allowed their volatiles to freeze and become stable
their large gravity allowed them to hold onto a large amount of volatiles
What does the Goldilocks or Habitable zone refer to?
the area on a planet where the cllinate is not too extreeme
the area around a star where water can exist as a liquid
the area around a star where life is confirmed to exist
the area around a star where planets form

The formation of Earth's moon
Increased solar activity
Which two parts of the solar system host most comet nuclei?
the Oort Cloud and the Asteroid Belt
the Oort Cloud and Kuiper Belt
the Asteroid Belt and Kuiper Belt
The Rings of Jupiter and Saturn
Aside from position how do the Oort Cloud and the Kuiper belt differ?
they are made of different types of material
their shapes are different
