Journey to the Center of the Earth the center of the Earth. The travellers are swept away as the sea rushes into the large open gap in the ground. 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
Figure of the Earth with its variety of land forms and water areas. This topographic surface is generally the concern of topographers, hydrographers, and geophysicists. While it is the surface on which Earth measurements are made, mathematically modeling it while taking the irregularities into account would be extremely complicated. The Pythagorean concept of a spherical Earth offers a simple surface that is easy to deal with mathematically. Many astronomical and navigational computations use a sphere to model the Earth as a close approximation. However, a more accurate figure is needed for measuring distances and areas on the scale beyond the purely local. Better approximations
