Why does earth have an inner core?
Denser materials originally sank to the core. The compression of these materials formed a solid inner core.

What is the temperrature of the earths inner core?
The temperature of the inner core can be estimated using experimental and theoretical constraints on the melting temperature of impure iron at the pressure (about 330 GPa) of the inner core boundary,...

How heavy is the inner core of Earth?
The Earth's inner core weighs about 1.53E+22 kg. CALCULATIONS: The inner core is spherical with a diameter of about 1,250 km (780 miles). -- Its volume (V = 4/3πr3) is about 1 Billion km cubed...

What is inside the inner core of the Earth?
The most current science suggests the inner core is nearly pure iron, hot enough to be molten, but because of high pressure it is forced into a metallic state. There are alternate theories (lots of...

What is the consistency of the inner core of the Earth?
The inner core of the earth is thought to be solid. It is extremely hot there, but the pressure prevents liquid from forming. We believe this based on the way sound travels through the earth, and...
