Energy resources and environmental pollution

Question 1

Atmospheric pollution behavior

Answer 1

Wind - dispersed over large areas
Electromagnetic radiation - photo chemical reactions
Infrared radiation - interactions

Question 2

What is the natural pH of water and how does it work

Answer 2

pH 5.6
CO2 dissolves to produce a dilute solution of carbonic acid
Acid rain is the term given to rain which is more acidic than this

Question 3

Acid deposition - what is wet and dry

Answer 3

Wet deposition - the process by which chemicals are removed from the atm and deposited on earth surface via rain, sleet, snow
Dry deposition - The falling of small particles and gases to the Earth without rain or snow

Question 4

What are natural sources of Acid rain

Answer 4

Volcano emissions
Fumaroles
Kilauea
Wildfires
Lightning

Question 5

What non-living things does acid rain effect

Answer 5

Limestone buildings

Corrode metal - railway lines, metal railings, water pipes, pylons, overhead power lines

Question 6

What are direct effects of acid rain

Answer 6

Where the acids are toxic

Question 7

What are indirect effects of acid rain

Answer 7

Where they cause other harmful environmental changes

Question 8

What direct effects does acid rain have on living organisms

Answer 8

Denature proteins in cell membranes and can inhibit enzyme action
Effect seed germination

Question 9

What indirect effects does acid rain have

Answer 9

Nutrients in soil are less available at a low pH
Changes the solubility of ions
reduced number of soil microorganisms

Question 10

Indirect effect of acid rain on living organisms

Answer 10

Aluminium and Alzheimers

Tken in by food, breathing and skin contact
