About 4000 degrees Celsius
It helps keep the Earth's interior hot.
The interior of the Earth is hot due to the heat generated from the decay of radioactive elements, leftover heat from the Earth's formation, and the pressure from the immense weight of the overlying rock layers.
Volcanoes bring up material from deep within the earth. earth's interior is very hot.
Hot molten rocks from the interior of the earth are called magma when they are beneath the earth's surface and lava when they reach the surface through volcanic eruptions.
Because the interior of the earth is hot.
Hot rock and liquid and solid metal.
If your question is why in the interior of the Earth so hot, then picture it this way: when you rap up in a blanket, you get warm right? Well what if you bundle up in more than one blanket? Say you put 4 or 5 blankets on. You'll get really hot. The layers on the Earth act as blankets for the core. That's why the interior is so hot.
after collisions subsided, the earth's surface was able to cool, but the interior remained hot
Heat is transferred from the interior to the surface of the Earth through a process called convection. In the Earth's mantle, hot material rises towards the surface, carrying heat with it. This movement creates convection currents that transfer heat from the interior to the surface.
The core is extremely dense, heavy and very hot.
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.
No. Earth's interior is so hot that you could not even make it through the crust.
