a) True
b) False

Answer 1

True. Warm air can hold more water vapor than cold air. The global trend over the past century has been one of decreasing precipitation.

Step-by-step explanation:

True. Warm air has the capacity to hold more water vapor than cold air. This is because warm air molecules are more energetic and can therefore hold more water molecules. As temperatures increase, the air has the ability to hold more water vapor, leading to increased precipitation.

One example of this can be seen in the water cycle. As warm air rises and cools, it loses its ability to hold as much water vapor, resulting in condensation and the formation of clouds. When these clouds become saturated with water vapor, they release precipitation in the form of rain, snow, or other forms.

Over the past century, there has been a general global trend of decreasing precipitation. This trend can be attributed to various factors such as changes in global climate patterns, deforestation, and human activities that contribute to climate change. However, it is important to note that regional variations in precipitation trends may exist.
