According to the nebular theory, how did the Sun form?
- From the gravitational pull of a nearby black hole.

What is the primary difference between terrestrial and Jovian planets?
- Terrestrial planets have rings, while Jovian planets do not.
- Terrestrial planets are located outside the asteroid belt, while Jovian planets are located inside.
- Terrestrial planets are much larger than Jovian planets.
- Terrestrial planets are made primarily of rock and metal, while Jovian planets are made primarily of gas. (correct)

Study Notes
Solar System Formation and Structure
- Nebular Theory: A cloud of gas and dust (nebula) collapses and rotates, forming the Sun at the center and planets revolving around it in a similar direction.
- Planets are categorized into Terrestrial, Jovian, and Dwarf planets, with distinct locations in the solar system.
- Students understand the order of planets from the Sun.
- Students can visually represent the relative sizes and distances between the Sun, terrestrial, and Jovian planets using models.
Planet Types
- Terrestrial planets are located closer to the Sun and are smaller and rocky (e.g., Mercury, Venus, Earth, Mars)
- Jovian planets are further from the Sun, larger and gaseous (e.g., Jupiter, Saturn, Uranus, Neptune)
- Dwarf planets are smaller than the inner, rocky planets, and located beyond Neptune (e.g., Pluto)
Solar System Structure
- The student's models demonstrate the layout of the Sun and its eight major planets (inner and outer).
- The models also portray the scales of size differences between the Sun, terrestrial and Jovian planets.
- The models demonstrate the relative distances between the Sun and the planets in our solar system.
