Answer 1

Outer planets are called gas giants.  Outer planets have a high gravity.

Answer 2

The correct statements are:

- Pluto is one of the outer planets;

- The outer planets are also called gas giants;

- The outer planets have high gravity due to their large size;

- The outer planets formed where temperatures were cooler;

The outer planets are in general much bigger than the inner planets, with the exception of the dwarf planet Pluto which is not very large. They are made out of gasses, and have very big and dense atmospheres. Because they are much bigger in general, and have more mass, these planets have bigger gravitational pull. The outer planets have all formed further away from the Sun, so they receive much less heat from it, thus they are in the cooler part of the Solar System and are all cold planets.
