8. Radioactive isotopes, differentiation of Earth’s iron core, gravity-driven compression,and meteoric bombardment all caused early Earth to ____________.A. glow brighter than the SunB. be much cooler than at presentC. be much hotter than at presentD. be much more oblong than at prese

Answer 1

Answer:

option C

Explanation:

the correct answer is option C.

All the activity such as Radioactive isotopes, differentiation of Earth’s iron core, gravity-driven compression,and meteoric bombardment will make the earth hotter than what it is at present.

Radioactive isotope  whose nuclei are unstable dissipate excess energy.

Differentiation of iron core means formation of into layer which includes iron.

meteorite bombardment will affect the atmosphere of the earth which protect harmful radiation.

All these activity will make earth hotter
