Why is rain always fresh water?

Why is rain always fresh water?

Precipitation is always fresh water, even when the water originated from the ocean. This is because sea salt does not evaporate with water. However, in some cases, pollutants in the atmosphere can contaminate water droplets before they fall to the Earth. The precipitation that results from this is called acid rain.

Does it rain fresh water in the ocean?

While it is true that the moisture from tropical systems comes from the oceans, the water from their rainfall is fresh, as it is from all weather systems. Salt and other impurities do not evaporate and instead remain in the ocean, which is why the oceans remain salty.

Why does it rain even in places that are not near the sea?

There must be an orographic effect. When air flows over continents, it must rise in altitude. As the air rises, its pressure and temperature decreases (perfect gas law). As air cools, it becomes saturated with water vapor, leading to precipitations.

Is rain over the ocean salty?

Rain is only marginally salty above oceans. It mainly consists of small amounts of salt which evaporate together with the water of the oceans. But most salt in the ocean is the result of rainwater washing down minerals from the shores of the ocean and taking them inside the water.

Can you drink rain water over the ocean?

If it is encrusted with dried salt, wash it in seawater. Normally, a small amount of seawater mixed with rain will hardly be noticeable and will not cause any physical reaction. In rough seas you cannot get uncontaminated fresh water. When it rains, drink as much as you can hold.

Does it rain more over the ocean or land?

The oceans receive just over their share, percentage-wise, of the world’s precipitation, about 70 percent. The remaining 30 percent of precipitation falls on the continents. Some areas of the world receive far more precipitation than others.

Does it rain more near the ocean?

These two factors play a big role in how the ocean impacts our weather. For example, because the ocean releases heat more slowly than land, coastal areas tend to be more temperate. Warm water is also evaporated from the ocean into the atmosphere, where it can condense and form clouds, which can eventually lead to rain.
