What Causes Rain?

What Causes Rain? Ever wondered what causes rain? You have seen rain before: small droplets of water coming down from the sky.

To understand what causes rain to fall from the sky, we need to start with water resources in nature and the sun. Water resources like oceans, ponds, and lakes are hit by the sun.

The sun would then pick moisture from these water resources (also called water vapor).

Once the water vapor (which is a gas) is picked up from the sun, it will disappear into the air. From there, the water vapor will then form clouds by rising. cooling, and changing. However, if these droplets are too big or heavy, they will then fall out of the sky, creating rain.

Types of Precipitation and Its Causes

To explore more on what causes rain, we need to identify the different raindrops and rainfalls and what causes them. There are four different types of raindrops which include:

1. Rain

Types of Precipitation

The most common raindrop that helps plants. It is caused by both cloud temperature and ground temperature. They both would need to be cold for it to create rain.

There are three different types of rain: rain (drops are only 0.5), drizzle (drops are small), and vigra (drops that don’t reach the ground).

2. Snow

Types of Precipitation

Type of rain you see predominantly during the winter. Snow is created when the temperature between clouds and the ground is below 0 degrees. Condensed water droplets then become ice crystals which then creates snow.

3. Sleet

Types of Precipitation

Sleet is like snow, but it is created differently. Rather than the temperature being cold, freeze moderately, creating a mixture of water and snow.

4. Hail

Types of Precipitation

The most severe type of raindrop, hail is created when rain encounters a layer of freezing air while going onto the ground. It will then solidify into two different shapes: one that is more deadly like ice pellets that are called hailstones.

Acid Rain : Causes and Effects

acid rain causes

Now that you know what causes rain, let’s talk about a type of rainstorm that is dangerous to the environment: acid rain. What causes acid rain? Here are the steps on how it is created:

  • It starts with a chemical reaction: two compounds called sulfur dioxide and nitrogen oxides are released into the air. Since both of these compounds can rise high into the air, they can mix with other elements like water, oxygen, etc.
  • Once these compounds mix with other elements, it creates acidic pollutants (as known as acid rain). As well as traveling high in the air, these compounds can go far distances with the help of the wind.
  • Acid rain can also collaborate with common weather like rain, sleet, snow, etc.

Why is acid rain dangerous?

acid rain causes

Here is how acid rain is dangerous, especially for plants :

  • For Forests : Acid rain dissolves essential nutrients for trees like magnesium and calcium. Acid rain releases aluminum into the ground, which makes it harder for trees to take up water. Trees in the mountains like fir and spruce are highly vulnerable to acid rain. Acid ran can bring unsavory attractions like insects, infections, and cold weather.
  • For lakes and streams : Acid rain decreases PH level in lakes and streams. The increase in low PH levels and aluminum makes water resources dangerous for wildlife that uses or live in these areas.
  • For People : Acid rain damages people as well. It can increase deadly respiratory diseases like asthma and bronchitis. It can even create health problems within a person or cause problems with people who already have health problems.

The Benefit of Rain for Health

It might sound like a crazy scenario of walking in the rain. No one likes walking in the rain. On the other hand, there are benefits of walking in the rain which include but does not limit to:

• The air is cleaner and fresh : During or after heavy rainfall, the air is cleaner and fresher. The reason for this is because raindrops capture dander, soot, or bacteria before hitting the ground, making it easier for people to walk and not get sick.

• Humidity and skin : Want something to help your skin? Walking in the rain helps with that! The humidity in the air keeps your skin fresh and young. The humidity also stops virus particles.

• Walking in heavy rain helps with weight : Yes, you can even burn more calories by just walking in the rain rather than walking during sunny weather. According to the International Sports of Medicine, walking in cold, rainy weather can make you lose weight more.

So if you ever plan on walking in the rain, remember to bring an umbrella, comfortable shoes/socks, and a rain jacket!


Rain is one of the most common forms of weather. It mostly occurs during spring, summer, and winter.

Knowing what causes rain and the different precipitation is essential in knowing what weather you are having in your area.

Rain is not always bad either as it is proven that it helps you with your body and keeps you safe from any bacteria or viruses. So go outside and take a walk in the rain!
