The main reasons the Earth's interior is hot are:
- The Earths crust is a good insulator, so interior heat is lost only slowly.
- The Earth was very hot when it formed (when the pieces of stuff came together to form the Earth). Much of this heat is still there today.
- The interior material is molten (liquid). They move around creating friction between these elements. Friction causes heat, so this motion of stuff in the liquid center results in heat from friction.
- When radioactive materials decay they release heat. There are such elements constantly decaying today.
The sources of heat combined with the Earth's crust keeping much of this heat from escaping is why the Earth's interior is hot.

Why inner planets are closer to the sun than outer planets?
The inner planets are closer to the sun than the outer planets because of the way the solar system formed. When the solar system was still a swirling disk of gas and dust, the inner planets formed closer to the center where it was hotter, while the outer planets formed in the colder regions farther away. This distribution of planets based on temperature led to the inner planets being closer to the sun than the outer planets.
What do the outer planets have that the inner planets do not have?
outer planets are gas giants whille inner planets are just rocky planets. that includes that outer planets have significant amount of mass than the inner planets
What are the distances between planets greater between the inner or outer planets?
The inner planets are closer together than the outer planets are.
Are the inner planets smaller than the outer planets?
Yes, the inner planets (Mercury, Venus, Earth, and Mars) are smaller than the outer planets (Jupiter, Saturn, Uranus, and Neptune). The outer planets are known as gas giants and are much larger in size compared to the inner terrestrial planets.
What are 3 differences between the outer and inner planets?
The inner planets are small, the outer planets are huge in comparison.The inner planets have rocky surfaces, the outer planets are gas giants.All of the outer planets have rings. None of the inner planets does.All of the outer planets have several moons, some of them quite large.
How are the inner planets different than then outer planets?
The inner planets are hotter because they are the closest to the sun the outer planets are the coldest because they are the farthest planets from the sun
How does the temperature of the inner planets compare to the temperature of the outer planets?
The inner planets are typically warmer than the outer planets. This is because the inner planets are closer to the sun and receive more direct sunlight, leading to higher temperatures. In contrast, the outer planets are much farther from the sun and are colder as a result.
What four inner planets are larger than the outer planets?
The inner planets are smaller than the outer planets.
Why inner planets are closer to the sun than outer planets?
The inner planets are closer to the sun than the outer planets because of the way the solar system formed. When the solar system was still a swirling disk of gas and dust, the inner planets formed closer to the center where it was hotter, while the outer planets formed in the colder regions farther away. This distribution of planets based on temperature led to the inner planets being closer to the sun than the outer planets.
Are the inner and outer planets different?
The inner planets are all rocky planets. The outer planets are completely made up of gases. The inner planets are much smaller than the outer planets.
What do the outer planets have that the inner planets do not have?
outer planets are gas giants whille inner planets are just rocky planets. that includes that outer planets have significant amount of mass than the inner planets
What are the distances between planets greater between the inner or outer planets?
The inner planets are closer together than the outer planets are.
Are outer planets larger and rockier than inner planets?
they are larger but not rockier then the inner planets the outer planets are made of gas.
Are the inner planets warmer than the outer planets?
No, the inner planets are not necessarily warmer than the outer planets. While the inner planets are closer to the Sun and therefore receive more sunlight, factors such as atmosphere composition, greenhouse gases, and internal heat sources can also impact a planet's temperature. For example, Venus, the second planet from the Sun, is hotter than Mercury, which is closest to the Sun, due to its thick atmosphere trapping heat.
How do inner planets differ?
Inner planets differ from outer planets because they have rocky core (excepting Pluto), and the are much smaller than outer planets, which are bigger and take more time to orbit Sun than inner planets because of their location. Outer planets are farther from the Sun than inner planets.
How does the outer mantle and the inner mantle differ?
the inner mantle is hotter than the outer mantle.
Is the distance between inner planets less than or greater than the distance between the outer planets?
The inner planets are closer together than the outer ones.
