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
