How does rain affect rocks, metals, and living organisms?

Answer 1

see explanation below

I don't think normal rain has effects. It is acid rain that has effects on metals, organisms etc. Acid rain is formed when sulfur containing fuels are burnt. When sulfur is released into the atmosphere, it reacts with oxygen and water, which finally forms sulfurous and sulfuric acid. These are very Strong and harmful acids, making the rain acidic (pH below 5.6). The other one is, nitrogen monoxide, as well as #NO_2#, #NO_3, NO_4#. This is from chemical industries e.g. fertiliser production. -The effects are they corrode metals,which damage buildings, bridges. - It dissolves rocks, over time. Especially calcium-based minerals such as marble and limestone are more affected. -It acidifys lakes and oceans, which kills fishes and other organisms.

Answer 2

Rain can weather rocks, causing erosion and the breakdown of minerals. It can also cause metals to corrode and rust. For living organisms, rain is essential for growth and survival, providing hydration and necessary water for plants and animals. However, excessive rain can lead to flooding, which can be destructive to both natural habitats and human settlements.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
