Question

The outer planets are made mostly of gas which makes them

Answer 1

Answer:

less dense than the solid inner planets.

Explanation:

A planet can be defined as a large celestial body having sufficient mass to allow for self-gravity and make it assume a nearly circular shape (hydrostatic equilibrium), revolves in an orbit around the Sun in the solar system and has a cleared neighborhood.

Basically, the planets are divided into two (2) main categories and these includes;

I. Outer planets: these planets are beyond the asteroid belt and comprises of jupiter, saturn, uranus and neptune, from left to right of the solar system.

II. Inner planets: these planets are the closest to the sun and comprises of mercury, venus, earth and mars.

The outer planets are made mostly of gas (hydrogen and helium) which makes them less dense than the solid inner planets. These gases are generally known to be less dense in terms of physical properties.
