Question

8.) why cant the outer planets sustain life?

Explanation:

Outer planets (gas/ice giants like Jupiter, Saturn, Uranus, Neptune) lack the key conditions for life as we know it:

1. They have no solid surface for complex life to anchor or develop, with deep, dense atmospheres that transition into liquid/supercritical fluid layers.
2. Extremely low temperatures (far below freezing) prevent liquid water, a critical requirement for life.
3. Their atmospheres are dominated by hydrogen, helium, and toxic compounds like methane or ammonia, with no breathable oxygen.
4. Intense gravitational forces, extreme atmospheric pressure, and harsh radiation environments would destroy any known life forms.

Answer:

Outer planets cannot sustain life because they lack a solid surface, have extremely cold temperatures that prevent liquid water, possess toxic, oxygen-free atmospheres, and have extreme gravitational, pressure, and radiation conditions that are incompatible with known life.
