All Flashcards
How is coal formed?
Decomposed plant buildup over millions of years (Carbon, hydrogen, and water).
How is oil formed?
Heat and pressure on aquatic organisms over millions of years (Carbon and hydrogen).
How is natural gas formed?
Organic matter trapped under sedimentary layers (Mostly methane - CH4).
What is the process of hydraulic fracturing?
Drilling, injecting fluid, creating fractures, releasing oil/gas.
How does combustion of natural gas occur?
CH4 + 2O2 → CO2 + 2H2O + Energy
How does combustion of methane occur?
CH4(g) + 2O2(g) → CO2(g) + 2H2O(g)
How does combustion of coal occur?
C(s) + O2(g) → CO2(g)
How does acid rain form?
SO2 and NOx react with water to form acid rain.
What are the effects of burning coal?
Releases CO2, NOx, SO2, and particulates, contributing to air pollution and climate change.
What are the effects of burning oil?
Releases greenhouse gases like CO, contributing to air pollution and climate change.
What are the effects of burning natural gas?
Releases greenhouse gases, particularly methane, contributing to climate change.
What are the effects of SO2 and NOx emissions?
React with water to form acid rain, damaging ecosystems.
What are the effects of greenhouse gas emissions?
Trap heat, leading to global warming and climate change.
What are the effects of oil spills?
Devastating to marine life and ecosystems.
What are the effects of fracking on groundwater?
Potential contamination of groundwater sources.
What are the effects of fracking on seismic activity?
Increased risk of earthquakes.
What are the effects of methane leaks?
Contributes to global warming due to methane's potency as a greenhouse gas.
What are the effects of habitat disruption from fracking?
Loss of biodiversity and ecosystem services.
How can transitioning to renewable energy sources help?
Reduces reliance on fossil fuels, decreasing greenhouse gas emissions and pollution.
How can improving energy efficiency help?
Reduces energy consumption, lowering the demand for fossil fuels.
