What discovery would weaken the primordial soup hypothesis of the origin of life? question 19 options: lightning was common on early earth. earth’s early atmosphere contained carbon dioxide, water, and trace gases. earth’s early oceans were warm and shallow. asteroid impacts were uncommon when life is presumed to have begun.

Asteroid impacts were uncommon when life is presumed to have begun.

Explanation:

The hypothesis about the origins of life on Earth are based upon the asteroid impacts. Basically, the hypothesis suggests that the asteroids brought the basic ingredients for the development of life on our planet. If a discovery is made though that in the period when life occurred the asteroid impacts were lacking, then this hypothesis will fall into water. This is because the hypothesis is directly dependent on the asteroid impacts, so if the case was that there weren't, or were very rare, the hypothesis will lose its basis.

Asteroid impacts were uncommon when life is presumed to have begun.

Explanation:

For many years, there was extreme heat on our planet. The oceans were warm and shallow, Earth's primitive atmosphere containing carbon dioxide, water, and other gases that made the earth an inhospitable environment. In addition, lightning was common on early Earth.

The high temperature of the earth was due to the many volcanic activities, which caused the release of gases and lava. The atmosphere and the earth's surface were characterized by the absence of the ozone layer, the effects of ultraviolet rays and lightning strikes, and the bombardment of bodies from space, that is, asteroid impacts were common on primitive earth, including these impacts. responsible for the beginning of life. It is well known that most of the carbon and water molecules in existence today originated from asteroids that fell on Earth during this period.
