Journey To The Centre Of The Earth

scientist1How far would you have to travel to reach the Earth’s core? And what would you see along the way? Discover what lies beneath…” (BBC)

BBC Future has a great feature on the journey to the centre of the Earth, along with all the creatures and odd things you’ll encounter along the way, both through the Earth and the ocean.

Did you know the Channel Tunnel is deeper than the deepest metro station? And yet no where near as deep as the deepest railway tunnel? The deepest dive by a blue whale is 500 metres, only just beaten by an Emperor Penguin at 535m. There are potential giant squids at 900m below sea level. The average depth of the Grand Canyon is 1610m. Apparently there’s a laboratory located at a depth of 2,500m, the Jinping Underground Laboratory in China. After 4,000m, you enter the Abyss, which gives way to the Trench zone at 6,000m. 11,000m is where the underwater section disappears, being as it is the deepest point on Earth, the Mariana Trench at the bottom of the Pacific Ocean. After a loooooong distance down, you reach the Inner Core at 4,14,0000m. After another 2.23 million metres, you finally reach the searing weightlessness of the centre of the Earth.

Toasty. Onwards!
