Question

Identify 6 differences between Terrestrial planets and Jovian planets.

1   Jovian planets formed outside the ice line; Terrestrial planets formed inside the ice line.

2   Terrestrial planets have regular moons; Jovian planets have captured moons.

3   Terrestrial planets have primary atmospheres; Jovian planets have secondary atmospheres.

4   Jovian planets are composed primarily of ices and gases; Terrestrial planets are primarily composed of rock and metal.

5   Terrestrial planets are smaller than Jovian planets in size and mass.

6   Terrestrial planets have solid surfaces; Jovian planets are gas and liquid throughout.

7   Terrestrial planets can be scarred by impact events on their solid surfaces; Jovian planets cannot show scars from impact events because of their thick atmospheres.

8   Terrestrial planets have storms that can persist for a few weeks to a few months; Jovian planets have storms that persist for years, decades, or centuries.

9   Terrestrial planets have slower rotations and shorter orbital periods than Jovian planets.

10    Terrestrial planets have large magnetic fields; Jovian planets have small magnetic fields.
