Question

Which statements describe the outer planets? Select three options. Pluto is one of the outer planets. The outer planets are also called gas giants. The outer planets have thin atmospheres. The outer planets have a high gravity due to their large size. The outer planets formed where temperatures were cooler.

Answer 1

Answer:

1. The outer planets are also called gas giants.
2. The outer planets have a high gravity due to their large size.
3. The outer planets formed where temperatures were cooler.

Explanation:

1. The outer planets are formed mostly by gas, which is one of the reasons why they are bigger than the inner planets and why they are called gas giants. The second reason is that they are bigger than the inner planets, such as the Earth, so they are called giants.
2. As regards their gravity, mass and gravity are directly proportional, the more mass a planet has, the more gravity this has. As the outer planets are the biggest ones, their gravity, is also the highest.
3. The outer planets were formed where temperatures were cooler, which means, that they were formed far away from the sun.

Answer 2

Answer:

The correct statements are:

- 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. 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.
