The Goldilocks Zone refers to the habitable zone around a star where the temperature is just right - not too hot and not too cold - for liquid water to exist on a planet.
Just because a planet or moon is in the Goldilocks Zone of a star, doesn't mean it will have life or even liquid water.
After all, Earth isn't the only planet in the Sun's Goldilocks Zone - Venus and Mars are also in this habitable zone, but aren't currently habitable.

Consider the following statements regarding the Goldilocks zone. Go...
Answer:
Goldilocks Zone:
The Goldilocks zone, also known as the habitable zone, is the region around a star where the temperature is just right for liquid water to exist on the surface of planets. It is neither too hot nor too cold, making it suitable for the potential development and sustainability of life.
Statement 1:
The first statement is correct. The Goldilocks zone refers to the area around a star where the conditions are conducive for liquid water to exist on the surface of planets. The presence of liquid water is considered a crucial factor for the development of life as we know it. If a planet is too close to its star, the heat would cause water to evaporate, leaving the planet dry and uninhabitable. On the other hand, if a planet is too far from its star, the low temperatures would freeze water, making it unavailable for life. Therefore, the Goldilocks zone is the region with the ideal temperature range for liquid water to exist.
Statement 2:
The second statement is incorrect. While Earth is indeed in the Sun's Goldilocks zone, it is not the only planet in this zone. There are other planets within the habitable zones of their respective stars that could potentially have conditions suitable for liquid water and the development of life. For example, Mars, a neighboring planet to Earth, is also in the habitable zone of the Sun, although it currently does not have liquid water on its surface.
Statement 3:
The third statement is incorrect. Being in the Goldilocks zone does not guarantee the presence of life or liquid water on a planet. While the presence of liquid water is more likely within the habitable zone, other factors such as atmospheric composition, the presence of an active geological system, and the planet's distance from its star also play significant roles in determining a planet's habitability. Additionally, the existence of life depends on various complex factors beyond just the presence of liquid water, such as the availability of organic compounds and suitable environmental conditions.
Conclusion:
In conclusion, the correct statement is statement 1. The Goldilocks zone refers to the region around a star where the conditions are ideal for liquid water to exist on a planet's surface. However, statement 2 and statement 3 are incorrect. Earth is not the only planet in the Sun's Goldilocks zone, and being in the habitable zone does not guarantee the presence of life or liquid water on a planet.
