The correct Answer is:
To analyze the statements provided, we can break down the reasoning step by step. ### Step 1: Understanding Statement 1 **Statement 1**: A cloudy night is hotter than a clear sky night. - During the day, the Earth absorbs heat from the Sun. At night, this heat begins to escape into the atmosphere and eventually into space. - On a clear night, without clouds, this heat can escape more easily into space, leading to cooler temperatures. - On a cloudy night, clouds act as an insulating layer, preventing some of this heat from escaping. Therefore, the temperature remains relatively higher compared to a clear night. ### Step 2: Understanding Statement 2 **Statement 2**: Clouds are bad absorbers of heat. - Clouds are primarily composed of water vapor and tiny water droplets. They do not absorb heat effectively compared to solid surfaces or the ground. - Instead of absorbing heat, clouds reflect some of the heat back towards the Earth, which contributes to the insulating effect mentioned in Statement 1. ### Step 3: Conclusion - Since clouds prevent heat from escaping during the night, it is indeed true that a cloudy night is hotter than a clear night. - Additionally, clouds being bad absorbers of heat supports the idea that they act as an insulating layer rather than allowing heat to escape. ### Final Answer Both statements are true, and Statement 2 provides a correct explanation for Statement 1. Therefore, the answer is that both statements are true, and Statement 2 is the correct explanation for Statement 1.
