give me the process, element and or compound, source, and sink for each of these things

a thunderstorm breaks out, with heavy downpours and significant lightning

a fire sparked and sweeps across a dry section of prairie

a day of rain leads to heavy amounts of water moving through and over the soil, eventually entering a nearby body of water

rainwater is acidic, some of it gradually dissolves some surface rocks

several days later, clover, which is a plant with nitrogen fixing bacteria k. it's roots, begins growing in the burnt out area of the prairie

weeks later, herbivores beging returning to the prairie eating and digesting the clover

bacteria fungi and insects begin breaking down the waste left by the herbivores

following several warm sunny days most of the surface soil has become dry again

carbon and sulfur from the fire are pushed deep underground. over millions of years they are transformed into coal

Here’s a detailed breakdown of the processes, elements/compounds, sources, and sinks for each of the scenarios you provided:

1. Thunderstorm with Heavy Downpours and Lightning

  • Process: Precipitation and lightning discharge.
  • Elements/Compounds: Water (H2O), nitrogen oxides (NOx from lightning), oxygen (O2).
  • Source: Atmospheric moisture, warm air rises, condensation in clouds, and electrical discharge.
  • Sink: Water infiltrates the ground, evaporates, or flows into bodies of water.

2. Fire Sweeping Across a Dry Section of Prairie

  • Process: Combustion.
  • Elements/Compounds: Carbon dioxide (CO2), water vapor (H2O), particulate matter, and heat.
  • Source: Dry biomass (grasses, shrubs), ignition source (lightning, human activity).
  • Sink: The heat and gases ascended to the atmosphere, and ash is deposited in the soil.

3. Heavy Rain Leads to Water Movement into Nearby Body of Water

  • Process: Runoff and erosion.
  • Elements/Compounds: Water (H2O), nutrients (N, P), sediments.
  • Source: Rainwater falling on soil and land surfaces.
  • Sink: Nearby rivers, lakes, or other bodies of water.

4. Acidic Rainwater Dissolving Surface Rocks

  • Process: Weathering (chemical weathering).
  • Elements/Compounds: Carbonic acid (H2CO3) formed from CO2 & H2O, minerals (e.g., calcite from limestone, granite).
  • Source: Atmospheric CO2, rainwater.
  • Sink: Dissolved minerals are carried away by water, potentially leading to soil nutrient depletion.

5. Clover Growth with Nitrogen-Fixing Bacteria in Burnt Prairie

  • Process: Plant growth and nitrogen fixation.
  • Elements/Compounds: Nitrogen (N2, fixed as NH3), carbon (from photosynthesis).
  • Source: Seeds of clover and nitrogen-fixing bacteria (e.g., Rhizobia) in the soil.
  • Sink: Biomass accumulation (clover plants) and nitrogen contributed back to the soil.

6. Herbivores Eating and Digesting Clover

  • Process: Consumption and digestion.
  • Elements/Compounds: Organic matters (carbohydrates, proteins from clover), nitrogen, carbon.
  • Source: Herbivores (e.g., rabbits, deer) feeding on clover.
  • Sink: Nutrient absorption into herbivore bodies, waste produced from digestion.

7. Bacteria, Fungi, and Insects Breaking Down Herbivore Waste

  • Process: Decomposition.
  • Elements/Compounds: Carbon (C), nitrogen (N), phosphorous (P), and organic matter.
  • Source: Waste left by herbivores (manure).
  • Sink: Nutrients are returned to the soil, becoming available for plants.

8. Drying of Surface Soil Following Warm Days

  • Process: Evaporation.
  • Elements/Compounds: Water (H2O).
  • Source: Warm temperatures and sunlight.
  • Sink: Moisture is lost to the atmosphere.

9. Carbon and Sulfur from Fire Transformed into Coal Over Millions of Years

  • Process: Fossilization (coal formation).
  • Elements/Compounds: Carbon (C), sulfur (S), hydrocarbons.
  • Source: Organic matter from burned plant material and sediments.
  • Sink: Deposited underground over geological timescales, transforming into coal under heat and pressure.

This breakdown provides a clear overview of the interactions between biological, geological, and atmospheric processes, emphasizing the flow of elements and compounds through the environment in each scenario.
