Q:

# How many miles is it from the Earth's crust to the Earth's core?

A:

The distance between the Earth's crust to the Earth's core is approximately 3,958 miles. Of this distance, the crust only makes up approximately 21 miles. Between the crust and the outer core is the mantle, which spans a distance of 1,774 miles.

The Earth's core is divided into two layers: the inner core and the outer core. The temperature of the mantle preceding the core ranges from 500 to 4,000 degrees Celsius. The core is speculated to be approximately 6,000 degrees Celsius, with a variable range of 500 degrees either way. As of 2014, the deepest distance humans have drilled into the Earth is 12 kilometers at the Kola Superdeep Borehole.

• A:

Dr. Inge Lehmann discovered the makeup of the Earth's inner core by studying how an earthquake's waves bounced off the core. It was previously thought that the core was made of liquid, surrounded by solid mantle and a crust. Lehmann found that the Earth's center is made of a solid inner core surrounded by a liquid outer core.

• A:

The earth's core is divided into two layers: the outer and inner core. The outer core borders the Earth's mantle and is approximately 1,430 miles in thickness. The inner core has a thickness of 750 miles, giving the core a combined thickness of 2180 miles.
