Notes Environmental Chemistry Effects of acid rain
Effects of acid rain
Acid rain has many damaging effects on the environment:
The strong acids in acid rain speed up the chemical weathering of rocks
Rivers, lakes and streams become more
Notes Environmental Chemistry Environmental Activities
Processes/Activities Affecting Environmental Chemicals
The chemicals in the air and food, that are used by living organisms, are
changed by the processes of cellular respiration and metabolism.

Notes Environmental Chemistry Carbon Cycle
2.51012 ton in atmosphere vs. 1.31014 in sea.
1011 ton yr1 exchange gives ~25 yr residency.
So oceans are the perfect sink for excess CO2.
10 ton in biosphere exchange 61010 ton yr1.

What is soil?
A layer of soil covers much of the Earths surface. What is soil made up of?
weathered rock particles
decaying remains of dead plants
and animals (called humus)
living things, including plants
