Nitrogen makes up about 78% of Earth's atmosphere, making it the most abundant gas. Oxygen is the next most abundant at roughly 21%, while argon is less than 1% and CO? around 0.04%. This composition is well documented by atmospheric science agencies. climate.gov
In which layer of the atmosphere is the ozone layer primarily located?
Stratosphere
Thermosphere
Troposphere
Mesosphere
The ozone layer resides mainly in the lower stratosphere, about 15 - 35 kilometers above Earth's surface. It absorbs most of the Sun's harmful ultraviolet radiation. The troposphere is below the stratosphere and contains weather phenomena. epa.gov
What term describes the warming of Earth's surface due to trapped infrared radiation by atmospheric gases?
Greenhouse effect
Ozone hole
Thermal inversion
Albedo effect
The greenhouse effect occurs when gases like CO? and methane trap infrared radiation, warming the planet. It is a natural process essential for life but can be intensified by excess greenhouse gases. Albedo effect refers to reflectivity, while ozone hole and thermal inversions are different phenomena. climate.nasa.gov
What is the primary driver of the recent increase in global average temperatures?
Increased solar output
Earth's orbital changes
Volcanic activity
Human emissions of greenhouse gases
Scientific consensus attributes recent global warming to anthropogenic greenhouse gas emissions, primarily CO? from burning fossil fuels. Solar output and volcanism can affect climate but not at the scale observed in the last century. Orbital changes operate on much longer timescales. ipcc.ch
What does the term 'albedo' refer to in climate science?
Heat capacity of the ocean
Greenhouse gas concentration
Surface reflectivity of solar radiation
Aerosol optical depth
Albedo is the fraction of incoming solar radiation reflected back to space by Earth's surface or atmosphere. Snow and ice have high albedo, while oceans and forests have low albedo. Changes in albedo can amplify warming or cooling. climate.nasa.gov
Which of the following is NOT a greenhouse gas?
Oxygen
Methane
Carbon Dioxide
Nitrous Oxide
Oxygen is not a greenhouse gas because it is not effective at absorbing infrared radiation. Gases like CO?, CH?, and N?O have molecular structures that trap heat, contributing to the greenhouse effect. epa.gov
The Keeling Curve is a time series that tracks atmospheric concentrations of which gas?
Ozone
Methane
Nitrogen Dioxide
Carbon Dioxide
The Keeling Curve charts the ongoing rise in atmospheric CO? measured at Mauna Loa Observatory since 1958. It is a key record demonstrating the increase in greenhouse gases over time. Methane and other gases are tracked by different observatories. keelingcurve.ucsd.edu
What does the term 'radiative forcing' refer to in climate science?
Amount of solar radiation reaching Earth's surface
Heat stored in the upper ocean
Change in energy balance at the tropopause
Annual variation in Earth's albedo
Radiative forcing quantifies the change in net downward radiative flux at the tropopause due to factors like greenhouse gas increases. Positive forcing leads to warming, and negative forcing leads to cooling. It is a foundational concept in climate modeling. ipcc.ch
Climate sensitivity is defined as the temperature change associated with what?
A 50% reduction in aerosols
The onset of an El Niño event
A 10% increase in solar output
A doubling of atmospheric CO? concentrations
Equilibrium climate sensitivity refers to the global average surface temperature change resulting from a sustained doubling of CO?. It typically ranges between 1.5°C and 4.5°C. It is central to projections of future warming. climate.nasa.gov
Which international agreement aims to limit global warming to well below 2°C above pre-industrial levels?
Kyoto Protocol
Paris Agreement
Geneva Convention
Montreal Protocol
The Paris Agreement, adopted in 2015, seeks to keep global temperature rise this century well below 2°C and pursue efforts for 1.5°C. The Kyoto Protocol focused on binding emission targets for developed countries. The Montreal Protocol addresses ozone-depleting substances. unfccc.int
What does IPCC stand for?
Independent Panel on Climate Conservation
Intergovernmental Panel on Climate Change
International Program on Carbon Control
Institute for Planetary Climate Coordination
The IPCC is the Intergovernmental Panel on Climate Change, established in 1988 by the UN to assess scientific information related to climate change. It publishes comprehensive assessment reports informing policymakers. ipcc.ch
El Niño is characterized by warming in which ocean region?
Western Arctic Ocean
Central and eastern tropical Pacific
North Atlantic
Southern Indian Ocean
El Niño refers to the periodic warming of sea surface temperatures in the central and eastern tropical Pacific Ocean. It disrupts global weather patterns, often causing droughts or floods in various regions. climate.gov
Milankovitch cycles influence climate over timescales of roughly how many years?
Monthly variations
Decadal oscillations
Tens to hundreds of thousands of years
Annual cycles
Milankovitch cycles are variations in Earth's orbit, tilt, and precession that occur over tens to hundreds of thousands of years. These changes alter the distribution of solar radiation and drive ice age cycles. climate.nasa.gov
Ocean acidification results primarily from which process?
Increase in ocean temperatures
Runoff of agricultural fertilizers
Melting of polar ice
Absorption of CO? by seawater
Ocean acidification occurs when seawater absorbs excess atmospheric CO?, forming carbonic acid and lowering pH. Rising temperatures have a secondary effect but the main driver is CO? uptake. noaa.gov
Which gas has the highest global warming potential over a 100-year timeframe?
Carbon dioxide
Nitrous oxide
Sulfur hexafluoride (SF?)
Methane
SF? has an extremely high global warming potential - over 23,000 times that of CO? over 100 years. Although its atmospheric concentration is low, its potency makes it a critical greenhouse gas for mitigation. epa.gov
What is the approximate atmospheric residence time of CO? after release?
About 10 years
About 100 years
Less than 1 year
About 1,000 years
CO? has an atmospheric residence time on the order of decades to centuries, with a mean of about 100 years for clearance of excess emissions. Some fraction remains in the atmosphere for millennia. This long lifetime makes CO? a critical concern for long-term climate change. noaa.gov
Which cloud type is generally associated with a net warming effect on Earth's climate?
Cumulus clouds
Cirrus clouds
Nimbostratus clouds
Stratus clouds
High, thin cirrus clouds allow incoming solar radiation to pass but trap outgoing infrared radiation, causing a net warming effect. Low, thick clouds tend to reflect more solar radiation and have a cooling effect. Cloud feedback remains a major uncertainty in climate models. climate.gov
The Suess effect refers to which phenomenon in atmospheric chemistry?
Enhanced uptake of CO? by oceans
Dilution of ¹?C in the atmosphere by fossil fuel CO?
Catalytic destruction of ozone by CFCs
Increased methane release from wetlands
The Suess effect describes the decrease in atmospheric radiocarbon (¹?C) concentration due to the addition of old carbon from fossil fuel combustion, which is devoid of ¹?C. This signature helps distinguish between carbon sources. usgs.gov
Which paleoclimate proxy uses trapped air bubbles to reconstruct past atmospheric composition?
Sediment layers
Coral reefs
Ice cores
Tree rings
Ice cores extracted from glaciers contain trapped air bubbles that preserve past atmospheric gases, providing direct records of historical CO? and CH? levels. Other proxies like tree rings and sediments record climate indirectly through growth or composition. nsidc.org
What range of equilibrium climate sensitivity does the IPCC Fifth Assessment Report cite?
1.5°C to 4.5°C
7.0°C to 10.0°C
0.5°C to 1.5°C
4.5°C to 7.0°C
The IPCC AR5 reports an equilibrium climate sensitivity likely between 1.5°C and 4.5°C for a doubling of CO?, reflecting model and observational constraints. Values outside this range are considered less probable. ipcc.ch
What drives the global thermohaline circulation, also called the ocean conveyor belt?
Solar heating of equatorial waters
Differences in seawater density due to temperature and salinity
Tidal forces from the moon
Surface wind patterns
Thermohaline circulation is propelled by density gradients in seawater, which depend on temperature (thermo) and salinity (haline). Cold, salty water sinks in polar regions, driving a global deep-ocean current. Wind patterns affect only surface currents. noaa.gov
The 'atmospheric window' refers to which range of infrared wavelengths?
0.3 - 0.7 micrometers
8 - 13 micrometers
1 - 3 micrometers
20 - 30 micrometers
The atmospheric window is the infrared wavelength band (8 - 13 µm) where water vapor and other gases absorb minimally, allowing heat to escape to space. Outside this window, greenhouse gases trap more infrared radiation. wileyonlinelibrary.com
Which Earth carbon reservoir contains the largest mass of carbon?
Atmosphere
Deep ocean
Fossil fuel reserves
Terrestrial biosphere
The deep ocean stores the largest carbon pool (~38,000 GtC), far exceeding atmospheric (~750 GtC) and terrestrial biosphere reservoirs. This makes the ocean a critical buffer for CO?. globalcarbonproject.org
Why does the stratosphere cool as greenhouse gas concentrations increase?
Greater heat loss from polar stratospheric clouds
Enhanced convection from the troposphere
Increased ultraviolet absorption by stratospheric ozone
Less infrared radiation reaches and warms it as more heat is trapped below
Rising greenhouse gases trap more infrared radiation in the troposphere, reducing the upward infrared flux that warms the stratosphere. As a result, the stratosphere cools while the lower atmosphere warms. agu.org
What distinguishes 'effective radiative forcing' from 'instantaneous radiative forcing'?
It accounts for long-term carbon cycle feedbacks
It considers only solar irradiance changes
It measures radiative change at Earth's surface only
It includes rapid adjustments in temperature, water vapor, and clouds
Effective radiative forcing includes the instantaneous change in radiative flux plus rapid adjustments such as water vapor and cloud changes before the surface temperature equilibrates. This provides a more comprehensive metric for climate response. ipcc.ch

Cheat Sheet

  1. Greenhouse Gas Radiative Forcing -

    Radiative forcing quantifies how gases like CO₂ and CH₄ alter Earth's energy balance, with CO₂ forcing approximated by ΔF = 5.35 ln(C/C₀) W/m² (IPCC AR5). Remember this formula to boost your atmosphere and climate change quiz score with a concrete example. Reviewing this core concept from NASA and NOAA sources is essential for any climate and climate change quiz section on greenhouse effects.

  2. Historical Global Temperature Trends -

    Since 1880, global temperatures have risen ~1.1 °C, forming the famed "hockey stick" curve in paleoclimate studies (NASA GISS). If you're tackling the global temperatures quiz, recall that the last decade holds eight of the ten warmest years on record. A simple mnemonic - "Hot Now High" - can help you remember the steep modern rise.

  3. Sea Level Rise Components -

    Global sea levels are climbing about 3.3 mm per year, driven roughly 50% by thermal expansion and 40% by melting glaciers and ice sheets (NOAA). When studying for your atmosphere and climate change quiz, note satellite altimetry data from missions like TOPEX/Poseidon. Think "Heat Expands, Ice Drips" to keep both causes in mind.

  4. Climate Feedback Mechanisms -

    Fast feedbacks (water vapor, albedo, clouds) and slow feedbacks (ice-sheet melt) amplify or dampen warming; overall climate sensitivity is about 3 °C per CO₂ doubling (IPCC). A handy mnemonic - "WAC: Water, Albedo, Clouds" - helps recall key fast feedbacks. Mastering feedback loops is a great way to ace the climate and climate change quiz's toughest questions.

  5. Carbon Cycle & Anthropogenic Emissions -

    The natural carbon cycle exchanges ~210 GtC annually between land, ocean, and atmosphere, while humans add ~10 GtC per year (Global Carbon Project). The Keeling Curve at Mauna Loa Observatory tracks rising CO₂ - essential for any global temperatures quiz context. Use "See Rocks Burn" (Sediments, Respiration, Biomass) to recall major carbon pools.
