5 Event Hydrosphere Biosphere Atmosphere Geosphere Yellowstone Forest Fires

6 EVENT - HYDROSPHERE Lack of rain, moisture in soil, plants Heat from fire removed moisture

7 EVENT - ATMOSPHERE Lightning strike may have started the fires Pollution (CO 2 ) may have been produced

8 EVENT - GEOSPHERE Heat from the fires may have caused some rocks to break

9 EVENT - BIOSPHERE Dead branches and pine needles on the ground may have provided fuel Seeds of some plants require that their outer shells be burned before they could sprout

10 GEOSPHERE - HYDROSPHERE Increased erosion of soil increases sediments in water

11 GEOSPHERE - BIOSPHERE decrease in plants may have result in increased soil erosion

12 GEOSPHERE - ATMOSPHERE Ash particles in the air carried by the wind and dropped on the ground miles away from the forest fires; the ash particles--which have a high pH—can change the pH of the soil

13 HYDROSPHERE - BIOSPHERE Ash particles in the water can clog the gills of fish and other aquatic organisms and choke them

14 HYDROSPHERE - ATMOSPHERE More rain in neighboring areas because ash particles in the air may have become condensation centers that allow raindrops to form Very dry, windy air can draw moisture out of the living grasses and trees through evaporation

15 BIOSPHERE - ATMOSPHERE Smoke in the air can coat the lungs of animals-- including people--and affect their ability to breathe
