Question

1. choose the best answer. the planet ____ is the only one with enough water on its surface to sustain life and allow water to exist in solid ice, liquid water, and gaseous states.

options: earth, jupiter, venus, mars

Explanation:

To determine the correct planet, we analyze the characteristics of each option:

• Earth: It has liquid water on its surface (oceans, lakes, rivers), ice caps (solid water), and water vapor in the atmosphere (gaseous water), and it sustains life.
• Venus: Has a harsh, hot environment with no stable liquid water on the surface.
• Jupiter: A gas giant with no solid surface, so no surface water in the traditional sense.
• Mars: Has some ice (solid water) and evidence of past liquid water, but not enough liquid water on the surface to sustain life in the same way Earth does, and the gaseous water presence is limited compared to Earth's diverse water states.

Answer:

A. Earth
