What zone does Earth exist in that potentially allows for life on our planet? Question 2 options: A: Red Zone B: Green Zone C: Goldilocks Zone (Habitable Zone) D: Danger Zone

Goldilocks Zone

Explanation:

The habitable zone is the area around a star where it is not too hot and not too cold for liquid water to exist on the surface of surrounding planets.

Imagine if Earth was where Pluto is. The Sun would be barely visible (about the size of a pea) and Earth's ocean and much of its atmosphere would freeze. On the other hand, if Earth took Mercury's place, it would be too close to the Sun and its water would form a steam atmosphere, quickly boiling off. The distance Earth orbits the Sun is just right for water to remain a liquid. This distance from the sun is called the habitable zone, or the Goldilocks zone.

Goldilocks Zone (Habitable Zone)

Explanation:

Habitable zone, the orbital region around a star in which an Earth-like planet can possess liquid water on its surface and possibly support life. Liquid water is essential to all life on Earth, and so the definition of a habitable zone is based on the hypothesis that extraterrestrial life would share this requirement.
