This is an early prototype for a simple program simulating the workings of a planet. The two tables below represent different "layers" of the planet.The first table is the asthenosphere, or the upper layer of the planet's mantle, where magma currents drive the motion of continental plates. The little arrows show the direction in which magma is currently moving. Red, blue, and yellow tiles represent respectively sites of orogenesis (mountain-building), trench opening, and subduction. The second table is the planet's actual surface, at first covered entirely in water. The numbers in each cell show the altitude of the rocky surface in kilometers, measured from the seafloor; altitudes of 3.5 km or more rise above the sea level. Click the "advance" button to move forward in time.Events that take place include large upwells of magma from the lower mantle, and continental drift, which may lead to mountain formation and opening of trenches. The contiental drift is not yet properly balanced. Next features to be added include spread of tectonic plates, surface erosion, and ocean currents.
