The Earth's core
Name: burbank school
How far down is the core of the Earth ?
Actually, the Earth has two cores--the inner core and the
outer core. The inner core is solid and is about 5100
kilometers down (approximately 3150 miles). Surrounding
the inner core is the outer core, which is believed to
be liquid, and starts about 2900 kilometers below the
surface of the earth (1800 miles).
Above the outer core is the mantle and above the mantle is
the crust, on which we live.
