Final answer:
When a parcel of air stays unsaturated, it means that the air is not holding as much moisture as it is capable of holding. In such cases, there is no condensation or precipitation occurring.
Step-by-step explanation:
When a parcel of air stays unsaturated, it means that the air is not holding as much moisture as it is capable of holding. In other words, the amount of water vapor present in the air is less than the maximum amount it can hold at that temperature. In this case, there is no condensation or precipitation occurring.
For example, if you have a dry desert area with low humidity, the air is unable to hold much moisture. As a result, the air will feel dry, and there will be no clouds or rain.
It's important to note that when the air becomes saturated and can no longer hold any more moisture, condensation occurs, and clouds or precipitation can form.
