Assessment: Chemistry and Green Environment

Why is it important to understand the atmosphere, hydrosphere, and lithosphere as INTERCONNECTED systems?

Is the greenhouse effect itself the environmental problem?

Which pollutant is primarily responsible for acid rain?

What is the correct term for the process where excess nutrients cause explosive algae growth, followed by oxygen depletion when the algae die?

After a radioactive release, iodine-131 (half-life ~8 days) and caesium-137 (half-life ~30 years) are both detected. Which will remain a significant environmental hazard for far longer, and why?

A city notices worse smog on hot, sunny, still days than on cloudy, windy days, even with similar traffic levels. What explains this?

Which best illustrates the principle of "green chemistry" — preventing pollution at the source rather than cleaning it up afterward?

Visible sunlight passes through the atmosphere largely unaffected by greenhouse gases, but infrared radiation from the Earth's surface is strongly absorbed by them. What does this difference explain?
