If the accretion process of planet formation was still going on in the solar system, how would life on earth be different? How would life be different?

Answer 1

If the accretion process were still going on, it seems unlikely that life would evolve at all.

As part of the accretionary process, the Earth was subjected to heavy bombardment during a period of 4.5 billion years ago. This suggests that the planet's surface and any surrounding water were extremely hot due to these collisions as well as ongoing volcanic eruptions that may have been caused by impacts resulting from pre-plate tectonic mantel convection.

According to one theory regarding the origin of life, life originated in hot black smoker regions of the ocean floor (where magma is erupting). However, in order for early life biochemicals to form, the temperature of the water must be just right—too hot or cold would cause them to break apart almost instantly.

The formation of complex organisms would be hampered by the unstable environment, and the Earth's surface would probably be uninhabitable for most life forms. Furthermore, the gravitational interactions between forming planets could disrupt Earth's orbit, resulting in extreme climate fluctuations and more obstacles for life to flourish. All of these scenarios would likely result in a very different Earth if the accretion process of planet formation were still ongoing in the solar system.

Answer 3

If the accretion process of planet formation was still ongoing in the solar system, life on Earth would likely be vastly different. The continual accretion of matter would result in frequent impacts from asteroids, comets, and other celestial bodies, leading to catastrophic events such as large-scale impacts and increased volcanic activity. These events could result in widespread destruction of habitats, extinction events, and alterations to Earth's climate and geology.

Additionally, the gravitational effects of ongoing accretion could destabilize Earth's orbit and rotation, leading to changes in the length of the day, seasons, and climate patterns. This instability could also affect the stability of Earth's magnetic field, which plays a crucial role in protecting the planet from harmful solar radiation.

Furthermore, the presence of large amounts of debris and dust in the solar system could obscure sunlight, leading to dimmer conditions on Earth's surface. This reduction in sunlight could impact photosynthesis and the availability of energy for life forms dependent on solar energy.

Overall, the continued accretion of matter in the solar system would likely create a much more dynamic and hazardous environment for life on Earth, with significant challenges to the survival and evolution of species.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
