Yellowstone Forest Fires
EVENT - HYDROSPHERE
• Lack of rain, moisture in soil, plants• Heat from fire removed moisture
EVENT - ATMOSPHERE
• Lightning strike may have started the fires• Pollution (CO2) 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 pH—can change the pH 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
