This is because the floating of clouds is caused by a combination of the earth's gravity and air buoyancy, and the density of the air is inversely proportional to the height of the air (perhaps inversely proportional to the square, which is not carefully calculated), and according to Archimedes' principle, the air buoyancy is directly proportional to the density of the air. Therefore, for clouds, you can find clouds of different densities, the buoyancy at the point of gravity equilibrium, after the line, is a contour line parallel to the earth's surface, that is, the "horizontal" line in our concept, (to be precise, it should be - concentric arcs with the center of the earth), after the cloud is in equilibrium (that is, floating in the air), its center of gravity must coincide with its buoyancy gravity equilibrium point, and for non-rigid body clouds, it can be infinitely decomposed into a number of unrelated small particles, arbitrarily arranged. The additional condition of the "contour line" determines that the final equilibrium state of the cloud must be horizontal.

The definition of wind, the horizontal movement of air, that has vertical wind.
Horizontal. Vertical full product subjective,
-
A point of view, there are erected clouds. In summer, it will appear on thick clouds (the bottom is of course flat, because the upstairs are bad), but this also means that heavy rain is coming.

Complement the content of the upper hand.
Correspondingly, wind is the result of the action of a pressure gradient force.
Some changes in air pressure are caused by storms, some are caused by uneven surface heating, and some are caused by atmospheric molecules being forced to flow from a relatively high pressure zone to a low pressure zone in a certain horizontal area.

A jet plane had just flown past in the sky.

It is very common for us to call it "airplane cable", and the traces of the plane just flying will automatically disappear after a while.

Why not ask them.
How to adjust. Or ask the administrator, it should be possible to adjust it.
-
Close it and restart the software to try.
-
Turn on the automatic rotation of the phone.
-
Is it that your phone is not set up to rotate automatically.
-
Can be opened in a folder.

Four years later, the cloud still has this problem.
-
Is landscape mode turned on?

This heavenly eye generally refers to this ability, which can see farther, more thoroughly, and can see the cause and effect of the three worlds.
Those who have heavenly eyes may not necessarily have three eyes.

Ordinary people are horizontal, but Erlang God and Wen Taishi are vertical.

Hello, about the problem that **** can't be horizontal**, the problem only appears on the android system, **** plug-in is on the android system, only vertical screen**, not horizontal screen**.
Hair that is too stiff and related to the growth of the hair itself can soften the hair and make it more conformable. >>>More
Clouds on Earth are multi-degree clouds that refer to the aggregates of water droplets or ice crystal colloids that remain in the atmosphere. Clouds are the tangible result of the vast water cycle on Earth. When the sun shines on the Earth's surface, the water evaporates to form water vapor, and once the water vapor is supersaturated, water molecules collect around the dust (condensation nuclei) in the air, and the resulting water droplets or ice crystals scatter sunlight in all directions, which gives the appearance of clouds. >>>More
Why do eggs have to be placed vertically, is it easier to keep fresh? I won't know the answer until I read it.
The water in the ocean, lakes, plant surfaces, and soil evaporates all the time, turning into water vapor and entering the atmosphere. Moist air containing water vapor rises upwards for some reason. During the ascent process, as the surrounding air becomes thinner and thinner, the air pressure becomes lower and lower, and the volume of the rising air expands. >>>More
This has to do with the cause of clouds.
Cloud formation is mainly caused by condensation of water vapor. >>>More
