Why clouds do not fall to earth

Clouds are masses that can be seen from droplets of water or frozen crystals suspended in the atmosphere above the surface of the earth or the surface of other planets.

First of all, the cloud has mass. In fact, a cloud of cumulus has a huge mass. For example, the cumulus cloud, the soft-white one that always appears on a bright day. This type of cloud has a water density of 0.5 g / m3.

Next, measure how big the cloud is. Say, our cumulus cloud is 1 km3, which means length, width, and height of about 1,000,000,000 meters. By knowing the mass of water types in clouds and clouds, the mass of water can be determined.

In this example, the water mass reaches 500,000,000 grams. That mass is approximately equivalent to 100 African elephants. Because it is rare elephant clay, then the weight is equivalent to 357 Honda HRV latest car, or 2939 motor Kawasaki Ninja 250 RR.
If all the cars or motors are hanging in the sky, they will surely fall. Added to the fact that the acceleration of gravity of 9.8 m / s2, it is certain the effect will be very tasteful on this earth.

That's if the cloud is still cumulus that was yes. Different clouds, different density of water. Different sizes, of course also different mass of water.

So how can thousands of tons of water in the form of clouds continue to hover in our sky?

As we know, the clouds are formed by the water that is exposed to sunlight. Thus, the temperature of this water vapor will be relatively warmer than the surrounding air temperature. Due to the convection of temperature, the surrounding air will have a higher temperature as well than normal air.

The air molecules then become more tenuous due to the warmer system. The air molecule's split causes the increase in volume, which certainly affects the downward pressure.

And correctly, the air will always move from high pressure to low pressure. Therefore, there is an upward force of thrust due to this air pressure difference.

It is this uprooting force aka updraft that is responsible for resisting the falling of cloud-forming particles due to the force of gravity.

Conclusion

Due to the very small particle size and large mass distribution, also because of updraft, clouds can remain in the sky as we see them all the time. But clouds are not as long as it hovers up there. The clouds will still fall.
When the clouds are formed, the tiny particles forming will continue to move due to temperature differences and pressure differences. Gradually, the constituent particles interact and form larger particles.
During the process, the water density begins to increase, the size of the raindrop enlarges, the mass increases, and the cloud falls due to gravity in the form of rain water.
When it rains, updraft can not stem the gravitational pull of a concentrated mass distribution over the initial formation of clouds.
