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]
What else can I help you with?
What is more hotter surface of the sun or center of the earth?
The surface of the sun is hotter than the core of the Earth. The surface of the sun can reach temperatures of about 5,500 degrees Celsius, while the core of the Earth has temperatures reaching up to 6,000 degrees Celsius.
What is hotter than Jupiter's surface?
Jupiter's surface is hotter than absolute zero, 0 Kelvin.
Which is hotter centre of the earth or surface of the sun?
The surface of the sun is hotter than the center of the earth. The core of the sun reaches temperatures of up to 27 million degrees Fahrenheit, while the Earth's inner core is estimated to be around 10,800 degrees Fahrenheit.
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.
Is thunder hotter than the sun?
The surface of the Sun is 5,778 Kelvin or about 5,500 oCThe core of the Sun is about 15,700,000 Kelvin or 15,700,000 oCA lightning bolt is about 30,000 oC so hotter than the surface of the Sun.A quasar is probably the hottest thing around, where the brightest onesconsume about 100 Suns per year.
Is the centre of the earth hotter than the surface of the sun?
no the surface of the sun is much is hotter.
Is it warmer underground or on the surface?
It is warmer underground than on the surface because the Earth's inner core is much hotter than the surface. The temperature increases the deeper you go beneath the Earth's surface due to the geothermal heat coming from the Earth's interior.
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
Which is hotter the center of the earth or the surface of the sun?
The surface of the sun is hotter than the center of the Earth. The sun's surface temperature is about 5,500 degrees Celsius, while the Earth's core temperature is estimated to be around 6,000 degrees Celsius.
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.
What is more hotter surface of the sun or center of the earth?
The surface of the sun is hotter than the core of the Earth. The surface of the sun can reach temperatures of about 5,500 degrees Celsius, while the core of the Earth has temperatures reaching up to 6,000 degrees Celsius.
Which is hotter the sun or the earths crust?
The sun is much hotter than the Earth's crust. The temperature at the Earth's core is estimated to be around 5700 degrees Celsius, whereas the temperature at the surface of the sun is about 5500 degrees Celsius.
What is hotter center of the earth or surface of the sun?
nothing
Is antares hotter than the sun?
yes it is hotter than the sun closest to us [earth]
Is earth hotter or colder than earth?
hotter
Is earth hotter than Venus?
Because Venus is closer to the sun, it is hotter than the Earth. Comparing temperatures of both these planet, you find that Venus' average surface temperature is 462 degrees Celsius and the Earthâ??s is 14 degrees Celsius.
