Weather vs Climate
This describes day-to-day changes in the atmosphere.
weather
This gas has increased due to burning fossil fuels.
carbon dioxide (CO2)
This process traps heat in Earth’s atmosphere.
greenhouse effect
Scientists use these to study past climates from ice.
ice cores
What is the difference between weather and climate?
weather is short-term atmospheric conditions, while climate is long-term average weather over time
Climate is best described as this type of weather pattern.
What is long-term average weather?
These include coal, oil, and natural gas.
fossil fuels
Without the greenhouse effect, Earth’s temperature would be this.
–18°C
Tree rings help scientists understand this about the past.
climate or weather conditions
What are some factors that affect weather?
temperature, air pressure, humidity, cloud cover, precipitation, and wind
Name one factor that affects weather.
temperature
humidity
wind
precipitation
air pressure
This period increased fossil fuel use and CO2 levels.
Industrial Revolution
Greenhouse gases absorb this type of energy.
infrared radiation
Scientists compare today’s climate to the past using these three sources.
temperature records, tree rings, and ice cores
What are some factors that affect climate?
latitude, ocean currents, wind and air masses, elevation, and closeness to water?
Give one factor that affects climate.
latitude, ocean currents, elevation, or distance from water
Scientists ruled out this as the main cause of climate change because it has decreased while temperatures rose.
Sun
Why is the greenhouse effect important for life?
It keeps Earth warm enough for life.
Scientists have collected temperature data since around this year.
~1850
Why is climate change a concern?
it can lead to harmful effects like rising sea levels, extreme weather, and environmental damage
Explain the difference between weather and climate.
Weather is short-term atmospheric conditions, while climate is long-term patterns over many years.
Name two possible causes of climate change.
volcanic eruptions, or changes in carbon dioxide
Explain how greenhouse gases warm the Earth.
They absorb heat and redirect it back toward Earth, trapping warmth.
Why do scientists use multiple sources of data to study climate change?
To compare and confirm patterns over long periods of time.
What can humans do to slow or reverse climate change?
reduce fossil fuel use and switch to renewable energy like solar, wind, and biofuels
