factors that allow diversity of life Flashcards
Formed from an older solar nebula generation
Star/Solar system birthdate
what factor stated: very long ago, planets would not contain enough heavy elements. We need to have elements part the first generation star level for living things
Star/solar system birthdate
Heavy elements
hydrogen , helium
4 fundamental forces
strong force, weak force, gravitational force, electromagnetic force
The sun needs to be in a stable burning phase (main sequence) for constant radiation and luminosity (heat & energy source)
Age of our sun
w/o the right mass/gravity, the atmosphere which surrounds us would move into space as well as us. This allowed the Iron catastrophe to occur which allowed Earth’s inner layer to form
right mass/gravity of the planet
the distance from the star where the average temperature of the planet allows liquid water to exist
habitable zone
