Consider the following statements about the Earth as a unique planet: 1. It is neither too hot nor too cold. 2. It lacks water but has air essential for survival. 3. Its air has life-supporting gases like oxygen. Which of the statements given above is/are correct?

The correct option is (c). Explanation Earth is the third planet from the Sun and is the only known planet in the solar system capable of supporting life. Its unique environment is defined by the presence of water, a life-supporting atmosphere, and moderate temperatures. - Statement 1 is correct: Earth is situated at an optimum distance from the Sun, often referred to as the "Goldilocks Zone." This positioning ensures that the planet is neither too hot nor too cold, allowing water to exist in liquid form and making conditions suitable for life. - Statement 2 is incorrect: Earth does not lack water; in fact, it is often called the "Blue Planet" because approximately 71% of its surface is covered with water. Water is a critical component for the survival of all known forms of life. - Statement 3 is correct: The Earth is enveloped by a layer of gases called the atmosphere. This atmosphere contains specific life-supporting gases, primarily oxygen (essential for respiration) and nitrogen, and protects the surface from harmful solar radiation. Key Takeaway: Earth is a unique planet because it possesses the three essential components for life: moderate temperature, the presence of liquid water, and a breathable atmosphere containing oxygen.
