All Flashcards
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 role of nitrogen in the atmosphere?
It is the most abundant gas, serving as the atmosphere's main structural component.
Why is oxygen essential for life?
It is necessary for respiration and is produced by photosynthesis.
How does water vapor affect weather patterns?
It contributes to humidity, cloud formation, and precipitation.
What is the impact of increased greenhouse gases?
They trap more heat, leading to increased global temperatures and climate change.
How does the ozone layer protect life on Earth?
It absorbs harmful ultraviolet (UV) radiation from the sun.
Why does temperature increase with altitude in the stratosphere?
Due to the absorption of UV radiation by the ozone layer.
What causes temperature to decrease with altitude in the troposphere?
As air rises, it expands and cools due to decreasing pressure.
What is the significance of the thermosphere?
It traps ions and particles from the sun, contributing to phenomena like auroras.
What is the role of the exosphere?
It is the interface between Earth's atmosphere and outer space, where satellites orbit.
How do human activities affect the concentration of greenhouse gases?
Burning fossil fuels, agriculture, and industrial processes release greenhouse gases into the atmosphere.
What is the role of nitrogen in the atmosphere?
It is the most abundant gas, making up the main structural component of the atmosphere.
Why is oxygen essential for life?
It is produced by photosynthesis and is necessary for respiration in most organisms.
How does water vapor affect weather patterns?
It contributes to humidity, cloud formation, and precipitation.
How do greenhouse gases contribute to global warming?
They trap heat in the atmosphere, leading to an increase in global temperatures.
How does the ozone layer protect life on Earth?
It absorbs harmful UV radiation from the sun.
How does altitude affect temperature in the troposphere?
Temperature generally decreases with increasing altitude.
Why does temperature increase with altitude in the stratosphere?
Due to the absorption of UV radiation by the ozone layer.
What causes the aurora borealis and australis?
Trapped ions and particles from the sun interacting with the atmosphere in the thermosphere and exosphere.
What is the role of the thermosphere?
It traps ions and particles from the sun, and its temperature increases with altitude due to solar radiation.
Where do satellites orbit?
In the exosphere, the outermost layer of the atmosphere.
