An Ocean of Water is found 620 miles below Earth's Surface
Two studies found evidence of oceans of water in Earth's lower mantle.
It is unclear how much water is being stored, but previous studies suggest it could be the same amount as all the oceans put together.
Without this water, life on Earth would cease to exist.
Water covers around 70 per cent of the Earth's surface, but a huge amount also lies inside our planet.
Two new studies suggest that there may be vast quantities of water as far as 620 miles (1,000 kilometres) below the surface.
Without this huge store of water, the geodynamic activity that causes volcanoes - which are important for generating soil and sustaining life on the planet - would cease.
