Inferred Properties of Earth's Interior (ESRT)

Front

What is the inferred temperature and pressure in Earth's stiffer mantle?

Back

3500°C and 0.4 million atmospheres.

Front

What is the state of Earth's outer core?

Back

Liquid, with an average density of approximately 11 g/cm³.

Front

At what depth is the boundary between Earth's outer core and stiffer mantle located?

Back

2900 km.

Front

What is the inferred state of rock material from the top of the stiffer mantle to the center of Earth?

Back

Solid, then liquid, then solid again to the center of the inner core.

Front

Which zone in Earth's interior is liquid due to its temperature being higher than its melting point?

Back

Outer core.

Front

What is the average density of Earth's outer core?

Back

Approximately 11 g/cm³.

Front

What is the temperature of the stiffer mantle?

Back

Inferred to be around 3500°C.

Front

What is the composition of the inner core?

Back

Solid.

Front

What happens to the state of rock material as you move from the stiffer mantle to the inner core?

Back

It transitions from solid to liquid and back to solid.

Front

What is the pressure like in the outer core?

Back

Inferred to be around 2.0 million atmospheres.
