Can the rain in the sky be drunk directly?

In fact, the rain is not clean and you can't drink it directly. If it rains, the clothes should be cleaned in time.

How did the rain come? ?

There is water vapor in the air at any time.

The sources of these vapors are oceans, lakes, rivers, pools, wetlands, undried clothes and so on.

When they are exposed to the sun, the water in them evaporates and becomes water vapor, which floats in the air.

When the water vapor condenses to a certain extent, the buoyancy of the air can no longer bear it, and it will fall to the ground to form rain.

Then why is the rainwater transformed by water vapor not clean?

This is because in the process of "traveling" from the sky to the ground, rain will bring many "small partners", such as smoke particles emitted by factories, dust above the ground, and even bacteria in the air will take the opportunity to mix in.

Therefore, when the rain falls to the ground, it is already filthy.

So, of course, rain can't be drunk.

So, why is the groundwater converted from rainwater drinkable?

Because the rainwater will pass through the thick sediment in the process of infiltration into the ground, the dust and bacteria will be filtered out, and the rainwater will become clean groundwater.

Rainwater treated by nature in this way is stored underground and becomes groundwater.

Groundwater, including well water and spring water, is drinkable.
