A

Smog

20
Q

Excessive——- leads to global warming

A

greenhouse gasses

21
Q

It is normal to have this otherwise the earth will be cold. However, excessive amounts would lead to Global Warming.

A

greenhouse gasses

22

Produced from the interaction of chemicals with the sunlight.

Can be brown or grayish blue.

A

Smog

23
Q

atmospheric conditions that trap smog and prevent its dispersal

A

Thermal Inversion

24
Q

It is formed in the atmosphere because of chemical reactions between pollutants.

A

Particulate matter, also called PM

25
Q

Harmful substances contaminating water ecosystems, degrading water quality and quantity, rendering it toxic to humans and other species.

Occurs when harmful substances contaminate a body of water

A

Water Pollution

26
Q

Origins of pollutants are diffuse and challenging to trace, such as agricultural runoff.

A

Non-point Sources

27
Q

Pollution can be directly traced to specific sources like factories, mines, and oil tankers.

A

Point Sources

28
Q

Consumption of contaminated organisms, such as fish, can lead to exposure to pollutants.

A
