As we all know, acid is a type of substance that is usually harmful to us humans and other living beings as well. So can it rain acid? Let's find out.

                                  The basics

Acid rain is basically water containing some harmful chemicals that pour down to us from the sky. Acid rain is made from sulfur dioxide and nitrogen dioxide. These two react to the moisture in the Earth, and it rains. The sulfur and nitrogen dioxide usually come from volcanoes, but about 90% of acid rain is caused by human activities such as large-scale factories and petroleum-based vehicles.

But, however, most of the acid rain can't harm us that much. But serious acid rain with a pH of 0 or 1 can harm us and other infrastructures. It can make stuff break down fast.

                                 Disadvantages

Acid rain isn't only harmful to us and structures. It can cause severe damage in the ecosystem of water sources. Then, in turn, it can harm the animals living there. It also takes away trees' leaves and stops their growth a lot. It adds aluminum to the soil, which can make it difficult for the trees to take up water.

                           Types of acid rain

There are two types of acid rain; Wet deposition and Dry deposition.

                              Wet deposition

Wet deposition is basically what we only think of. Wet deposition is where sulfuric and nitric acid falls into the ground and reacts with rain, snow, and even hail. Then, in combination with sulfur and nitrogen, we get wet deposition acid rain.

           

                              Dry deposition

Dry deposition is something that we don't really think of that much when we think of acid rain. It is found in dry areas. Since there isn't any rain, snow, or hail, it just mixes up with the dust and smoke, and then it sticks into buildings, structures, cars, and others.
