What is the Earth's core primarily composed of?

Back

The Earth's core is primarily composed of iron and nickel.

Front

What is the difference in density between the Earth's crust and core?

Back

The core is more dense than the crust.

Front

What state of matter is the outer core?

Back

The outer core is in a molten (liquid) state.

Front

What is the approximate density range of the outer core?

Back

The density range of the outer core is approximately 9.9 - 12.2 g/cm³.

Front

Which layer of the Earth is solid?

Back

The inner core is solid.

Front

What causes the inner core to be solid despite high temperatures?

Back

The high pressure at the core causes the inner core to be solid.

Front

How does the density of oceanic crust compare to continental crust?

Back

The oceanic crust is denser than the continental crust.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle.

Front

What is the asthenosphere?

Back

The asthenosphere is a semi-fluid layer beneath the lithosphere that allows tectonic plates to move.

Front

What is the primary difference between the inner core and outer core?

Back

The inner core is solid, while the outer core is molten.
