Answer:
The Earth is the fifth largest of the planets in the Solar System. The Earth planet is located at the right distance to have liquid water (H2O) on its surface.
The statement indicating that the "earth is the third planet from the sun and its distance is just right for life" best explains why earth's place is suitable for life.
The Earth planet is larger than the other three terrestrial planets (i.e., Mercury, Mars, Venus) and smaller than the gas giant planets (i.e., Jupiter, Saturn, Uranus, Neptune).
Earth is the third planet from the Sun (after Mercury and Venus). The Earth orbits at a strategic distance from the Sun so that water (H2O) molecules can exist in liquid form.
Water molecules in a liquid state are a key requirement for life because they function as a solvent, thereby being an excellent mediator of life's chemical reactions.
In conclusion, the statement indicating that the "earth is the third planet from the sun and its distance is just right for life" best explains why earth's place is suitable for life.
