1. The correct answer is c. As air gets warmer, its relative humidity increases. This means that warm air has the ability to hold more water vapor. To understand why this happens, we need to look at the concept of relative humidity. Relative humidity is a measure of how much water vapor is in the air compared to the maximum amount of water vapor the air can hold at a specific temperature. When air gets warmer, its capacity to hold water vapor increases, so if the amount of water vapor in the air remains constant, the relative humidity will decrease. However, if the amount of water vapor in the air also increases as the air gets warmer, then the relative humidity will increase. Therefore, the correct answer is c.

2. The correct answer is c. The temperature at which water vapor condenses out of the air is called the dew point. To understand this concept, we need to know that air can hold a certain amount of water vapor before it reaches its saturation point. When the air is saturated, the water vapor begins to condense into liquid droplets, forming dew. The temperature at which this condensation occurs is called the dew point. This is the point at which the air is holding as much water vapor as possible at the given temperature. Therefore, the correct answer is c.

3. The correct answer is b. Very high feathery clouds are called cirrus clouds. To remember this, you can use the word association technique. Think of the term "cirrus" as sounding similar to "sirius" and "sirius" is the brightest star in the sky. Just like cirrus clouds are high up in the sky and appear feathery, so does the brightest star, sirius, shine from a great distance. Therefore, the correct answer is b.

4. The correct answer is a. As air cools, the amount of water vapor it can hold decreases. To understand this, we need to know that the ability of air to hold water vapor depends on its temperature. When air cools, its capacity to hold water vapor decreases, so if the amount of water vapor in the air remains constant, the relative humidity will increase. However, if the amount of water vapor in the air also decreases as the air cools, then the relative humidity will remain the same. Therefore, the correct answer is a.

5. The correct answer is d. On average, a snowfall of 10 centimeters would equal a rainfall of 3 centimeters. To understand this conversion, we need to know that snow is less dense than rain. When 10 centimeters of snowfall melts, it compresses and becomes denser, resulting in a smaller volume of water. On average, every 10 centimeters of snowfall can be expected to melt and yield approximately 3 centimeters of rainfall. Therefore, the correct answer is d.
