Answer 2

Here are the True/False sentences with explanations:

1. Drops of water make clouds. (True) - When warm air rises, it cools down, causing the water vapor in the air to condense into tiny droplets. These droplets combine to form clouds.

2. Rain is a drop of ice falling on the Earth. (False) - Rain is formed when water vapor in the atmosphere condenses into liquid water droplets. It is not associated with ice falling directly to the Earth. However, in some cases, rain can start as ice crystals or snowflakes at higher altitudes before melting into liquid raindrops.

3. Plants can live without air. (False) - Plants require air, specifically carbon dioxide, for the process of photosynthesis. Through photosynthesis, plants convert carbon dioxide into oxygen and produce energy.

4. Snow is an ice crystal falling down from the sky. (True) - Snow forms when water vapor in the atmosphere directly crystallizes into ice without passing through a liquid phase. These ice crystals then fall to the ground as snowflakes.

5. The sun can never heat water in the sea. (False) - The sun's energy can indeed heat the water in the sea. Sunlight contains infrared radiation that can penetrate the surface of the water and transfer heat energy, warming the water.

6. The warm air goes up and becomes hot. (False) - Warm air rises due to its lower density compared to cooler air. As it rises, it cools down due to the decrease in atmospheric pressure, which causes the air to expand and lose heat. Therefore, the warm air does not become hotter as it ascends.
