Hydrosphere Geosphere Yellowstone Forest Fires Event Atmosphere Biosphere

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

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

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

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

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

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

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 p. H—can change the p. H of the soil

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

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

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