Answer:
The rain containing excess of acids called an acid rain.
Explanation:
The rain becomes acidic because of harmful gases like carbon dioxide,
sulphur dioxide and nitrogen dioxide which are emitted as smoke from
vehicles and industries. These harmful gases dissolve in rain drops to
form carbonic acid, sulphuric acid and nitric acid respectively.
Effects of Acid Rain
Acid rain makes the water of lakes, ponds and rivers too acidic
due to which fish and other aquatic animals get killed.
Acid rain eats up the leaves of the trees gradually. By losing
leaves, the trees die. Acid rain also damages crop plants in the
fields.
Acid rain damages the metal structures like steel bridges, etc
when it falls on them.
Acid rain damages the surfaces of buildings and monuments made
up of marble.
Answer;
All minerals are Solid, Inorganic, Naturally Orcurring, have a defintite Chemical Compostion, and also have definite Crystalline Structure
Explanation;
A mineral is a naturally occurring, inorganic solid with a definite crystalline structure and chemical composition.
The physical characteristics of minerals include traits which are used to identify and describe mineral species. These traits include color, streak, luster, density, hardness, cleavage, fracture, tenacity, and crystal habit.
All minerals are solid, meaning each has a definite volume and shape.
All minerals are inorganic, which means they are not produced by living things or from the remains of living things.
All minerals are naturally occurring.
All minerals form crystals, which are solid geometric forms produced by a repeating pattern of atoms or molecules.
