what is one way the video describes earth around the time of its formation?
a molten planet under constant bombardment
a cold ice - covered sphere with no atmosphere
covered in deep oceans and lush vegetation
already inhabited by microbial life

Explanation:

The video likely describes Earth's early formation as a molten planet due to intense heat from gravitational accretion and radioactive decay. Constant bombardment by asteroids and meteoroids further contributed to its molten state. Other options (cold, ice - covered; lush vegetation; microbial life) are inconsistent with the harsh, high - energy environment of Earth's infancy.

Answer:

A. A molten planet under constant bombardment
