Explanation / Answer

67. Rock labeled C: Igneous rocks are formed by the cooling of the magma from 1200 C to the 600 C or beyond and in this diagram this rock which is labeled as C is the best candidate as it starts to cool down from the magma at the greatest temperature level of 1100 C.
68. The era labeled as B corresponds to the Cenozoic: The Cenozoic era is the part of Phanerozoic eon and its the topmost part of this eon.
69. The period labeled E: It’s a sub-period in the geological timescale or a subsystem of the geological record. It’s earliest or the lowermost of the sub-periods of the Carboniferous period.
70. The Era labeled A as Paleozoic: It’s the longest of the Phanerozoic eras, it’s divided into six periods as Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian.
