CaCO3 calcium carbonate

H2SO4 sulphuric acid

Acid rain kills

trees.

WHY?

When acid rain

reaches the

ground, it

dissolves some

of the minerals

and carries

them away. This

process is

called leaching.

Without these

minerals, trees

can die.

Acid rain kills

fish in lakes.

WHY?

Many forms

of water life

are sensitive

to the pH of

the water. If

the pH

changes, they

can die.

Fish die

because they

don’t have

food to eat.
