Answer:
Pollutants are responsible for creating an imbalance of the substances that leads to a negative impact in a particular part of the earth like air, water, soil, noise, and more.
Primary pollutants are the pollutants that are directly generated from their sources such as activities by humans like air and water pollutants from the car, from ships, that affects the organs of humans like lungs, eyes, stomach and reduces our immune system and our life. Indirectly affect us. In the environment, they increase toxic substances in high amounts that cause various negative impacts.
Secondary pollutants form due to the reacting of primary pollutants and natural resources. Acid rain is an example of the secondary pollutant result which is formed due to dissolved sulphuric acid in rainwater. It also affects the skin of humans and affects the environment by increasing acidity to soil and water.
Ten times as much for each
magnitude increase; thus a magnitude 7 is 1000 times more displacement than
magnitude 4. Most earthquakes happen at the edges of a
tectonic plates. A break in earth's crust along which blocks of crust
slide relative to one another is called earthquakes.
