Why do clouds usually form high in the air instead of near Earth's surface?
As air rises the moisture in it slowly reaches its saturation point and when this happens, tiny crystals of water start to condense and form clouds.
This process usually occurs higher up in the atmosphere when the temperature drops and an air parcel starts to get saturated as it rises. When all the right conditions are in place, the small crystals of water start to condense out and clouds form. See pic.
However, low level clouds can form on the ground, but only when vampires are lurking around!! Kidding of course.... "Fog" is a low lying cloud that will form if the temperatures and water saturation conditions are right.

Clouds usually form high in the air instead of near Earth's surface because of the specific conditions required for cloud formation. Clouds form when air containing water vapor rises and cools, causing the water vapor to condense into tiny water droplets or ice crystals. This process typically occurs in the atmosphere where the air is cooler and less dense. As air rises, it expands and cools due to decreasing atmospheric pressure. When the air reaches its dew point temperature, which is the temperature at which air becomes saturated with water vapor, condensation occurs, leading to cloud formation. Since the lower atmosphere near Earth's surface is usually warmer and more stable, air tends to rise less frequently, making it less conducive to cloud formation compared to higher altitudes where the air is cooler and more prone to vertical movement.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
