Earth’s distance from the Sun keeps temperatures mild—warm enough to prevent freezing and cool enough to avoid boiling. This balance lets water remain mostly in liquid form, which is essential for supporting life on Earth.

Class 8 Science Curiosity Chapter 1 Exploring the Investigative World of Science Question Answer
Earth is located in the “habitable zone,” a region around the Sun where temperatures are just right for water to stay in liquid form. If Earth were much closer, water would boil away; farther away, it would freeze. Liquid water is essential for life—it’s needed for drinking, growing food and supporting all living processes. This perfect distance is a key reason Earth can support such a wide variety of life, unlike other planets in our solar system.
