Planet’s Remains Buried In Earth’s Interior, Shaping Its Geography, Study Shows

The large low-velocity provinces (LLVPs) in the deep Earth mantle may be relics of Theian mantle materials. The remains of another planet that collided with the Earth and formed the Moon are still buried deep inside the Earth's interior, according to a new study. PHOTO BY DENG HONGPING/SWNS  

The remains of another planet that collided with the Earth and formed the Moon are still buried deep inside the Earth’s interior, according to a new study.

An international, interdisciplinary team of researchers says Large Low-Velocity Provinces (LLVP) deep in our planet’s mantle could be relics of a planet that collided with Earth around 4.5 billion years ago which have since influenced our planet’s geography.
