Why does water vapor decrease with altitude?

As temperature increases, then an increasing amount of liquid or solid water can vaporize into the air. The amount of water vapor is the air tends to decrease with altitude. This is because temperatures decrease with height and the availability of a moisture source is farther away.

Do planes get wet in clouds?

They do get wet. They just don’t get very wet. Very tiny droplets are accelerated around the plane with the air.

Can planes move clouds?

Unless you’re using binoculars you’re unlikely to see clouds moving much because of a plane. When wind moves clouds, the whole mass of air is moving and clouds (the water droplets) are moving with it. On the other hand airplanes try to be as stremlined as possible and minimize the drag to be more efficient.

What are clouds made of?

A cloud is made of water drops or ice crystals floating in the sky. There are many kinds of clouds. Clouds are an important part of Earth’s weather.

What happens to water vapor at high altitudes?

If a volume of air contains its maximum amount of water vapor and the temperature is decreased, some of the water vapor will condense to form liquid water. This is why clouds form as warm air containing water vapor rises and cools at higher altitudes where the water condenses to the tiny droplets that make up clouds.

Why does water vapour decreases from the equator towards the poles?

Water vapor decreases from equator to pole due to temperature (lower temperatures mean lower absolute humidity), and increases over ocean compared with land (because of the availability of water to evaporate).

Do airplanes stand still in the air?

Techincally, there is only one way for the aircraft to remain hanging motionless in the air: if weight and lift cancel each other out perfectly, and at the same time thrust and drag cancel each other out too. But this is incredibly rare. To stay in the air and sustain its flight, an aircraft needs to be moving forward.
