For awhile, scientists have presumed that the interior of the Earth is hot and full of melted rock and a variety of elements. However, a recent discovery has changed what science thinks is beneath our feet. They have discovered a substance called Ice VII or Ice 7. This particular kind of ice is different than regular ice that we might see in everyday life. Ice has different grades and this provides new proof that really dense and hard ice might be just beneath our feet.
