However, there is still much we don't know about the mantle. For example, it is still not known exactly how thick the mantle is and what its composition is. It is also still a matter of debate whether there is a hidden ocean inside the mantle.
Some scientists believe that there could be an ocean inside the mantle that could hold up to 20% of the Earth's water mass. This ocean is believed to have formed after the formation of the Earth, due to heat and pressure from the Earth's core.
Finding an ocean inside the mantle would help us better understand the Earth's internal structure and geological processes. It could also be a source of new life.
Whether there is an ocean inside the mantle is a question that scientists have been investigating for years. However, the exact answer to this question is not yet known. However, as research continues, we hope that this question will soon be solved.
