The four inner planets—Mercury, Venus, Earth, and Mars—are primarily composed of rock and metal. They have solid surfaces and are often referred to as terrestrial planets due to their rocky composition. Unlike the gas giants, these planets have relatively thin atmospheres and are characterized by features such as mountains, valleys, and impact craters. Their densities are higher compared to the outer gas giants, reflecting their solid materials.

The inner planets are the first 4 planets from the sun, they are made of rock. After the in er planets is an asteroid belt. Behind the belt are the 4 outter planets. They are made of gas and are called "gas giants". These are called outter planets.


What is the major difference between the inner and outer planets as it relates to their composition?

The difference is that the 4 inner planets are solid. The first 2 outer planets are completely made up of gas and the last 2 planets, while also made up of gas, are mostly frozen, so scientists call them ice giants.Pluto is no longer considered a planet.


Why is the temperature higher on these 4 inner planets than the 5 outer planets?

The inner planets are closer to the Sun than the outer planets, so they receive more direct sunlight and heat. Additionally, the inner planets have solid surfaces that can absorb and retain heat, while the outer planets are mostly composed of gas and have no solid surface to absorb heat. This combination of factors leads to higher temperatures on the inner planets compared to the outer planets.


Is earth an inner or outer planet?

Earth is an inner planet. The inner planets are Mercury, Venus, Earth, and Mars. The outer planets are Jupiter, Saturn, Uranus, and Neptune. The inner planets are warmer and have solid, rocky cores. The outer planets are much cooler, bigger and are mostly, if not entirely, gas.

How do the massive outer planets differ from the inner terrestrial planets?

The massive outer planets are composed mostly of gas and ice, while the inner terrestrial planets are made primarily of rock and metal. Outer planets are much larger in size and have thick atmospheres, while inner planets are smaller and have thin or no atmospheres. Outer planets also have many moons and rings, while inner planets have few or no moons.
