All Flashcards
What is the process of aerobic decomposition?
Microorganisms break down organic matter in the presence of oxygen, releasing CO2.
Describe the process of anaerobic decomposition.
Microorganisms break down organic matter in the absence of oxygen, releasing methane (CH4) and CO2.
How do VOCs contribute to smog formation?
VOCs react with other pollutants (NOx) and sunlight to form ground-level ozone, a component of smog.
Describe the process of CO2 release during respiration.
Living organisms convert food into energy, releasing CO2 as a byproduct.
What are the steps of aerobic decomposition?
Microorganisms break down organic matter + Oxygen -> CO2 + Water + Energy.
What are the steps of anaerobic decomposition?
Microorganisms break down organic matter -> Methane (CH4) + CO2 + Other gases.
Describe the process by which lightning strikes generate NOx.
High temperatures from lightning cause rapid oxidation of nitrogen and oxygen, creating NOx.
Describe the process by which plants release VOCs.
Plants release volatile organic compounds (VOCs) during photosynthesis.
What are the effects of high CO2 levels?
Global warming and climate change.
What are the health effects of particulate matter?
Respiratory issues, especially for those with pre-existing conditions.
What is the effect of sulfur dioxide release from volcanoes?
Contributes to acid rain.
What is the effect of deforestation on CO2 levels?
Reduces carbon sinks, leading to increased atmospheric CO2 levels.
What is the effect of increased methane release?
Contributes to global warming as methane is a potent greenhouse gas.
What are the effects of volcanic eruptions?
Release ash, SO2, CO2, and other gases, affecting air quality, visibility, and climate.
What are the effects of forest fires?
Release PM, CO, VOCs, greenhouse gases, and toxins, harming health and the environment.
