What effects does acid rain have on trees and plants?

Answer 1

Acid rain can affect the earth in many different ways. Below you can see how soil, trees, lakes, buildings and people are affected when acid rain falls on the earth.

Soil

Acid rain can damage soil by destroying many vital substances and washing away the nutrients. Soils naturally contain small amounts of poisonous minerals such as Mercury and aluminum. Normally these minerals do not cause serious problems, but when acid rain falls on the ground and the acidity of the soil increases, chemical reactions occur allowing the poisonous minerals to be taken up by the plant roots. The trees and plants are then damaged and any animals eating them will absorb the poisons, which will stay in their bodies.

Trees

The acid takes important minerals away from the leaves and the soil. Without these minerals, trees and plants cannot grow properly. Damaged trees lose their leaves, have stunted growth and damaged bark. This makes it easier for fungi and insects to attack the tree, and as a result the tree may die.

Acid rain not only damages soil but can also affect the trees directly. Pollutants can block or damage the little pores on the leaves through which the plant takes in the air it needs to survive.

The tree on the right is normal, while the tree on the left is less dense. This is an effect of acid rain.

Lakes and water

As the lake becomes more acidic the fish find it more difficult to reproduce successfully. It is not only the acid in the water that kills them, but also poisonous minerals like aluminum that are washed out of the surrounding ground into the water. The birds that eat the fish also begin to suffer as the harmful minerals build up inside

their bodies.

Buildings

When sulphur pollutants fall on to buildings made from limestone and sandstone they react with minerals in the stone to form a powdery substance that can be washed away by rain. Famous buildings like the Statue of Liberty in New York, the Taj Mahal in India and St. Paul's Cathedral in London have all been damaged by this sort of air pollution.

Acid rain can also damage stained glass windows in churches, railway lines and steel bridges. The acid rain slowly eats away them all. Building materials crumble away, metals are corroded, the colour of paint is spoiled, leather is weakened and crusts form on the surface of glass.

Health

When we breath in air pollution, the very fine particulates can easily enter our lungs, where they can cause breathing problems, and over time even lead to cancer. Drinking water is contaminated with chemicals released by acid rain. Aluminium and lead in water can be poisonous at high levels.

Answer 2

Acid rain can be simply defined as precipitation that contains large amounts of sulfuric and nitric gases. However, to discern the significance of its meaning we should learn about its surrounding circumstances; its effect in the environment and on the living organisms that thrive in it.

Answer 3

Acid Rain can cause deformities in trees and will cause less growth.

It also makes the soil acidic and hence plants are not able to grow properly.

Answer 4

It is going to cause the death of trees!

Answer 5

in some cases acid rain can cause damage and or death of the plant. it all depends on the amount of acid rain and what level the acid falls on the pH scale.

Answer 6

i really dont no

Answer 7

Kill them or cause them to grow poorly.
