Documentary Description

Two thousand miles below the Earth’s surface, there is a vast ocean of molten iron. Learn about a proposed mission to the centre of the earth to

find some answers. What would it be like to travel to the center of the Earth? It's a place of unimaginable heat and pressure, where no life can survive. Yet without it we would perish—for it holds the key to our existence on this planet. Thousands of miles below the surface, the Earth's core generates a protective magnetic shield around the planet. Now, scientists have uncovered evidence that this armor could be fading. Are weak spots in the Earth's shield a sign that our planet's magnetic poles are on the verge of flipping? Naked Science challenges our traditional geological models and takes you deep to the center of Earth.
