Answer 2

Answer:

1) There are a total of 4 major types of pollution:

• Air Pollution - This is a type of pollution where harmful wastes such as dust particles and gasses that combines with the atmosphere making it poisonous. Ex: Smoke from Vehicles and Industries

• Water Pollution - This is a type of pollution where harmful wastes such as plastic, wastes dis-created from industries mix with the water in water bodies making it turn in to a bad state. Ex: Heavy metals like Lead and Cadmium

• Land Pollution - This is a type of pollution where harmful wastes that are mostly biodegradable are mixed into the soil for many years making it unstable for the agrarian production and killing the animals such as earthworms in the soil. Ex: Sulphur that mixes with oxygen in the air making sulphuric acid and mixing with rain when it falls damages the soil in the area.

• Sound Pollution - This is a type of pollution that is produced due to a harmful propagation of noise with ranging impacts on the activities done by human and animal life. Ex: Noise from very loud speakers,

2) Natural Resources are resources that exist without any action from humankind, that is, resources that are formed naturally by nature. Some examples are Wind, Sunlight, Tidal and etc.

3) Stars are made up of hydrogen and helium for the production of light.
