What is the greenhouse effect?
The greenhouse effect is the warming of the Earth’s surface due to the trapping of heat by greenhouse gases in the atmosphere.
Name three major greenhouse gases.
Carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).
True or False: The greenhouse effect is entirely a natural phenomenon.
False. While the greenhouse effect occurs naturally, human activities have significantly increased the concentration of greenhouse gases.
Fill in the blank: The process by which human activities increase greenhouse gases is known as __________.
anthropogenic emissions.
How do human activities contribute to the greenhouse effect?
Human activities such as burning fossil fuels, deforestation, and industrial processes release large amounts of greenhouse gases into the atmosphere.
What role does the geosphere play in the greenhouse effect?
The geosphere interacts with the atmosphere through processes like weathering of rocks, which can release carbon dioxide.
What is the biosphere?
The biosphere is the global sum of all ecosystems, where living organisms interact with each other and their environments.
True or False: The biosphere has no impact on the greenhouse effect.
False. The biosphere influences the greenhouse effect through processes like photosynthesis and respiration.
What is the hydrosphere?
The hydrosphere includes all the water found on, under, and over the surface of the Earth.
How does the hydrosphere affect climate?
The hydrosphere affects climate by regulating temperatures and weather patterns through the storage and movement of water.
What is the cryosphere?
The cryosphere encompasses all the frozen water on Earth, including glaciers, ice caps, and sea ice.
True or False: Melting ice in the cryosphere contributes to rising sea levels.
True.
What is one effect of increased greenhouse gases on the cryosphere?
Increased greenhouse gases lead to accelerated melting of ice and glaciers in the cryosphere.
Multiple Choice: Which of the following is NOT a greenhouse gas? A) Oxygen B) Water vapor C) Methane
A) Oxygen
What is the primary source of carbon dioxide emissions from human activities?
Burning fossil fuels for energy and transportation.
Fill in the blank: Deforestation contributes to the greenhouse effect by reducing __________.
carbon sequestration.
What is carbon sequestration?
The process of capturing and storing atmospheric carbon dioxide.
True or False: The greenhouse effect is beneficial for life on Earth.
True. It keeps the planet warm enough to sustain life.
What is the relationship between the greenhouse effect and global warming?
The greenhouse effect contributes to global warming by increasing Earth’s average temperature.
What human activity has the largest impact on the biosphere?
Agriculture and land use changes.
Multiple Choice: Which process absorbs CO2 from the atmosphere? A) Respiration B) Photosynthesis C) Combustion
B) Photosynthesis
What is the effect of ocean acidification?
Ocean acidification occurs when CO2 is absorbed by seawater, leading to harmful effects on marine life.
Fill in the blank: The __________ is a major carbon sink that helps mitigate climate change.
ocean.
How does the geosphere store carbon?
Through the formation of fossil fuels and carbonate rocks.
