Earth's internal heat comes from a combination of residual heat from planetary accretion (about 20%) and heat produced through radioactive decay (80%).[62] The major heat-producing isotopes in the Earth are potassium-40, uranium-238, uranium-235, and thorium-232.[63] At the center of the planet, the temperature may be up to 7,000 K and the pressure could reach 360 GPa.[64] Because much of the heat is provided by radioactive decay, scientists believe that early in Earth history, before isotopes with short half-lives had been depleted, Earth's heat production would have been much higher. This extra heat production, twice present-day at approximately 3 billion years ago,[62] would have increased temperature gradients within the Earth, increasing the rates of mantle convection and plate tectonics, and allowing the production of igneous rocks such as komatiites that are not formed today.[65]

Is the core of the earth hotter than the core of the moon?
The outer core is liquid. Its pressure is low enough and its temperature high enough for it to melt. The inner core is solid. Both its pressure and temperature are higher than the outer core, but the increased pressure overwhelms the increased temperature, keeping the inner core from melting.
How hot is the crust?
The crust is the cool part of the Earth. It is the surface we live on. It should be at a comfortable temperature until it reaches down to the mantle, the next layer. That area will be hotter. Then at the center, is the core. That is the hot part of the Earth's interior. It is about 3500° C. Estimates vary from 2000 to 7000, but it is HOT!
What is hotter than Jupiter's surface?
Jupiter's surface is hotter than absolute zero, 0 Kelvin.
What is the primary reason why the surface of Venus today is some 450C hotter than the surface of Earth?
A combination of things. First, Venus is much closer to the sun than earth, so its surface receives more radiant energy from the sun. Add to that the fact that Venus is surrounded by a thick layer of carbon dioxide clouds, which create a runaway greenhouse effect. Bottom line: Venus's surface is about 800 degrees hotter than earth's surface.
Is the Earth's core hotter than the Earth's crust?
very much hotter.
Is the centre of the earth hotter than the surface of the sun?
no the surface of the sun is much is hotter.
Why is a White Dwarf hotter than the sun?
A white dwarf is what remains of a star's interior, which is much hotter than the surface because it is closer to the source of fusion.
Which is hotter the sun or the earth?
The Sun is much much hotter than the Earth. The Sun's surface temperature is approximately 5,800 K. The surface temperature of the Earth, by contrast, rarely exceeds 331ºK

Why Earth's interior is warmer than its surface?
Earth's surface is free to radiate heat into space. The interior is not. The interior does transfer heat the the surface, but rather slowly. It is hot due to residual heat from Earth's formation and from the heat generated by the decay of radioactive elements.
Which planets are hotter than the Earth?
All eight planets have a surface temperature, though it varies as the planets distance from the sun varies. Closer planets to the sun generally have a higher surface temperature, while further planets have a colder surface temperature.
Is earth hotter than Venus?
No, Venus is hotter than Earth. Venus has a much thicker atmosphere composed mainly of carbon dioxide, which creates a strong greenhouse effect and traps heat, leading to surface temperatures that are hotter than those on Earth.
Is the mantle of the Earth hot?
"Hot" is a relative term, but it's definitely hotter than the surface.
Is earth hotter or colder than earth?
hotter
Why earths interior is warmer than earths surface?
Earth's surface is free to radiate heat into space. The interior is not. The interior does transfer heat the the surface, but rather slowly. It is hot due to residual heat from Earth's formation and from the heat generated by the decay of radioactive elements.
What is hotter than Jupiter's surface?
Jupiter's surface is hotter than absolute zero, 0 Kelvin.
