All Flashcards
What is denitrification?
The process where nitrogen is released back into the atmosphere.
What is photosynthesis?
The process by which plants convert light energy into chemical energy, producing oxygen.
What are greenhouse gases?
Gases that trap heat in the atmosphere, contributing to global warming.
What is the ozone layer?
A region in the stratosphere containing high concentrations of ozone, protecting Earth from UV radiation.
What are CFCs?
Chlorofluorocarbons; compounds that deplete the ozone layer.
What is the troposphere?
The lowest layer of Earth's atmosphere where weather occurs.
What is the stratosphere?
The layer of the atmosphere above the troposphere, containing the ozone layer.
What is the mesosphere?
The layer of the atmosphere above the stratosphere, characterized by decreasing temperature with altitude.
What is the thermosphere?
The layer of the atmosphere above the mesosphere, characterized by increasing temperature with altitude.
What is the exosphere?
The outermost layer of Earth's atmosphere, merging with space.
What is the effect of increased greenhouse gases?
Increased global temperatures and climate change.
What was the effect of CFCs on the ozone layer?
Depletion and thinning of the ozone layer.
What is the effect of deforestation on CO2 levels?
Increased CO2 levels in the atmosphere due to reduced carbon sequestration.
What is the effect of burning fossil fuels?
Increased CO2 emissions and contribution to global warming.
What is the effect of increased UV radiation exposure?
Increased risk of skin cancer, cataracts, and damage to ecosystems.
What is the effect of livestock farming?
Increased methane emissions, contributing to global warming.
What is the effect of melting ice caps?
Rising sea levels and habitat loss for polar species.
What is the effect of increased CO2 in the ocean?
Ocean acidification, harming marine life.
What is the effect of transitioning to renewable energy?
Reduced greenhouse gas emissions and decreased reliance on fossil fuels.
What is the effect of improved energy efficiency?
Reduced energy consumption and decreased greenhouse gas emissions.
What is the effect of burning fossil fuels on the atmosphere?
It increases the concentration of CO2, a major greenhouse gas, leading to global warming.
What is the impact of CFCs on the ozone layer?
CFCs deplete the ozone layer, reducing its ability to absorb UV radiation.
What is the effect of deforestation on atmospheric CO2 levels?
Deforestation reduces the number of trees available to absorb CO2, leading to higher atmospheric concentrations.
What is the consequence of increased UV radiation reaching the Earth's surface?
Increased risk of skin cancer, damage to ecosystems, and harm to marine life.
What is the effect of increased methane emissions from agriculture?
Methane is a potent greenhouse gas, so increased emissions contribute to global warming.
What is the environmental consequence of global warming?
Melting ice caps, rising sea levels, altered weather patterns, and disruptions to ecosystems.
What is the impact of increased nitrous oxide emissions?
Nitrous oxide is a powerful greenhouse gas, intensifying global warming.
What is the effect of air pollution on human health?
Respiratory problems, cardiovascular diseases, and other health issues.
What is the impact of climate change on biodiversity?
Habitat loss, species extinction, and altered ecosystems.
What is the effect of increased CO2 on ocean acidity?
Increased CO2 absorption leads to ocean acidification, harming marine life.
