Most living things exist on Earth's surface, but some living things (including humans) have ventured or explored many kilometres in depth.

How it works

Push down the knob and watch sliding markers stop at the deepest recorded point for mountains and trenches.

How deep have we dug or dived?

Background

Humans, plants and animals have only scratched the Earth’s surface. The Earth’s crust is up to 100 kilometres thick, and it is more than 6000 kilometres to Earth’s centre.

Finding the science in your world

The deepest humans have ever dug was a Russian bore hole, which reached 12 kilometres deep. Humans have not gone down this bore hole.
