Why the inner palnets also called terrestrial planets?

They all have a clearly defined rocky terrain. The outer gas planets dont have a clearly defined surface or terrain.


How are inner planets all similar?

The inner planets are similar in their composition, which is mostly iron and various types of rock.


What is the inner and outer planets and contrast the two groups of planets?

The four inner, rocky planets are also known as the terrestrial planets. These are; Mercury, Venus, Earth and Mars. The four outer gas giant planets are Jupiter, Saturn, Uranus and Neptune. The inner planets are smaller and have a higher average density. The outer planets are much larger, but have no real surface - just atmosphere that gets thicker as you travel inwards. The outer planets all have a ring system (the inner planets dont) while the outer planets have captured a lot more natural satellites or moons than the inner planets.

Why dont the terrestrial planets have rings?

Two main reasons. Firstly, the inner planets are a lot less massive, so their overall gravitational pull is lower than the larger gas planets. Secondly, there is, or has not been, as much material closer to the sun. As a result, the inner planets have captured fewer moons between them. These tend to be the cause of the rings in the outer planets, where orbiting bodies can break up and scatter around the planet in discs.

Are the 4 inner planets more rockey then the 4 outter?

Each of the four inner rocky planets have a 'rocky' terrain, a well defined solid surface. The four outer planets, the gas giants, dont have a clear surface, they are made of gas which gets thicker and thicker further into the planet. So the answer is yes.
