Answer 1

soil is the outermost layer of earth in few centimetres which is fertile and useful for growing trees and it is formed by stones and rocks and it is rich in minerals.
In now days we use many urea, insecticide,pesticides means chemicals and by polythene(plastic) glasses soil is polluting and by factories chemicals are released in soil as well as in water also so water and soil is polluting by this.
air pollution is increasing by smoke releasing through factories, vehicles trains. dust particles through construction.
