Question

2. How is the lithosphere formed?
​

Answer 1

Answer:

The solidification of the magma ocean, upon which the process of the formation of the lithosphere is dependent, most likely began with the formation of a forsterite (or forsterite-rich peridotite) slab at a depth of about 100 km followed by the solidification of Earth’s surface, cooled by heat radiation from the surface and the cooling effect of the early atmosphere. It is shown that under the thermal conditions of the magma ocean, carbonate rocks were unstable and decomposed, releasing carbon dioxide into the atmosphere.
