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.

2) Radioactive decay.

∙ 15y agoIt depends on the planet. Some, such as Venus, are hot because gases in their atmosphere capture heat from the sun. Proximity to the planet's sun also affects how hot the planet is.

Are the inner planets smaller than the outer planets?
yes the inner planets are much smaller then 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
Inner an outer planet similarities?
The inner and outer planets are The same because The Inner planets are not made out of gas The outer planets are bigger than inners The outer planets are the coldest The Inner planets are rocky The inner planets are terrestrial The outer planets can't support life The inner planets have iron cores The outer are the furthest from the sun The outer planets haveno rocky surface
What are the distances between planets greater between the inner or outer planets?
The inner planets are closer together than the outer planets are.
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
Why are inner planets different than outer planets?
Inner planets. are inner & outer planets. are outer
What four inner planets are larger than the outer planets?
The inner planets are smaller than the outer planets.
How do the inner planets travel around the sun than the outer planets?
Inner planets travel faster than outer planets
Are the inner planets smaller than the outer planets?
yes the inner planets are much smaller then 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
Inner an outer planet similarities?
The inner and outer planets are The same because The Inner planets are not made out of gas The outer planets are bigger than inners The outer planets are the coldest The Inner planets are rocky The inner planets are terrestrial The outer planets can't support life The inner planets have iron cores The outer are the furthest from the sun The outer planets haveno rocky surface
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 warmer than the outer planets?
The outer planets generate their own heat and the inner planets are warmed by the sun.
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.
What are 3 special characteristics of the three outer planets?
The inner and outer planets are The same because The Inner planets are not made out of gas The outer planets are bigger than inners The outer planets are the coldest The Inner planets are rocky The inner planets are terrestrial The outer planets can't support life The inner planets have iron cores The outer are the furthest from the sun The outer planets haveno rocky surface
