After spending hours being swept along at lightning speeds by the water, the raft ends up inside a large volcanic chimney filling with water and magma. Terrified, the three are rushed upwards, through stifling heat, and are ejected onto the surface from a side-vent of a stratovolcano. When they regain consciousness, they discover that they have been ejected from Stromboli, a volcanic island located in southern Italy. They return to Hamburg to great acclaimProfessor Lidenbrock is hailed as
Geology of the Moon produced melt sheets of molten rock that covered portions of the surface that could be as thick as a kilometer. Examples of such impact melt can be seen in the northeastern part of the Mare Orientale impact basin. The surface of the Moon has been subject to billions of years of collisions with both small and large asteroidal and cometary materials. Over time, these impact processes have pulverized and "gardened" the surface materials, forming a fine-grained layer termed "regolith". The thickness of the lunar regolith varies between beneath the younger maria, to up to beneath the oldest surfaces of the
