Q:

What is the center of the earth called?

A:

The center of the Earth is called its inner core, which is solid and surrounded by the liquid outer core. The outer core is surrounded by the solid mantle layer, which moves in response to a temperature difference of at least 2,700 degrees Fahrenheit between it and the inner core.

Scientists estimate that the temperature at the intersection between Earth's inner and outer cores is about 10,800 degrees Fahrenheit, which is about the same temperature as the sun's surface. The movement of the mantle, together with the Earth's rotation, generate the Earth's magnetic field. The Earth's surface layer surrounding the mantle is called its crust.

  • Q:

    How do we know the Earth has a liquid core?

    A:

    The biggest reason scientists theorize that the Earth has a liquid outer core and a solid iron inner core is that shear seismic waves, which cannot move through liquid, disappear when they hit the outer core only to reappear in the inner core. By measuring how both shear and pressure seismic waves travel through the core, scientists are not only able to determine the makeup up the inner and outer cores, but also their respective sizes.

  • Q:

    What are the four layers of the earth?

    A:

    The Earth is divided into four layers: crust, mantle, outer core and inner core. The crust is the only layer of Earth that hosts life, as the mantle, inner core and outer core are too hostile for organisms to exist.

    What is the temperature in the center of the Earth?

    A:

    As of April 2013, scientists have recorded the temperature in the center of the Earth to be 6,000 degrees Celsius. This is 1,000 degrees hotter than the measurement previously recorded from an experiment run 20 years prior.

  • Q:

    How thick is the earth 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.
