That's mostly due to very high heat and pressure, very little of which actually dissipates through solid rock to reach the surface. We don't actually know the exact temperature, but measurements from earthquakes show that the core is about 5700 kelvin, comparable to the very outer parts of the sun. The inner core is eventually expected to cool down after a very long time, and there's evidence that it's already happened in many other planets.

What is a molton rock that reaches Earth's surface?
Lava.
What type of rock is the earth's outer core made of?
Earth's outer core is not made of rock. It is made of molten metal; mostly iron and nickel.
Is granite found in the core of the earth?
Granite is an intrusive igneous rock found in the continental crust of the Earth, not the core. The core is primarily composed of iron and nickel.
What are the parts of earth's surface?
The layers are in this order, from core to crust. 1 inner core 2 outer core 3 mantle 4 crust We are on the crust. The inner core is solid iron the outer is liquid iron the mantle is hot rock the crust is dirt and rock.

What is a molton rock that reaches Earth's surface?
Lava.
The earths volume is made up of what?
Molton rock known as mantle magma, for the most part. There is also an iron core, the inner portion of which is probably solid.
What is Liquid or molton rock found within the Earth?
magma
What type of rock is the earth's outer core made of?
Earth's outer core is not made of rock. It is made of molten metal; mostly iron and nickel.
What is made up of mostly iron in the earth?
Iron is denser than rock, and therefore sinks through the layers of molten liquid rock, to the center.
Is granite found in the core of the earth?
Granite is an intrusive igneous rock found in the continental crust of the Earth, not the core. The core is primarily composed of iron and nickel.
What The center inner iron core of the earth is?
A super hot ball of: Iron, Nickel and roughly 20% Rock.
What is the term for the hot rocks inside the earth that becomes lava when it reaches the earth surface?
its called molton rock

What are the structural layers of the earth?
From outer to inner, the layers of the Earth are the Crust, a thin, rock layer, then the Mantle, the thickest layer of Earth, then the Outer Core, a liquid mixture of Nickel and Iron, and then the Inner Core, a solid ball of Nickel and Iron.
What is the earths core like?
No. The inner core of Earth is made of a solid nickel-iron alloy. The outer core is made of liquid nickel and iron.
Is the earths core made of hard rock?
No. The Earth's core is divided into two parts: a solid inner core and a liquid outer core, moth made mostly of iron.
