Natural Hazards
Flooding, severe weather, volcanic eruptions, earthquakes are all examples of?
What are natural hazards?
gases in the atmosphere that trap heat, such as CO2 and methane
What are greenhouse gases?
A natural cycle of earth warming and cooling has been occurring since its beginnings; however, humans have contributed to speeding up the warming faster than earth can cool itself off. This time period marks the greatest increase of greenhouse gas emissions in history.
What is The Industrial Revolution?
Some refer to the natural emission of this gas into the atmosphere as "cow farts".
What is methane?
a man-made environmental impact that increases air, water, and soil pollution
What is deforestation?
Hurricanes and tornadoes are examples of these.
What are severe weather hazards?
a greenhouse gas released by natural processes and human activities, especially burning fossil fuels
What is carbon dioxide (CO2)?
These beloved animals bless us with meat and milk, but they also curse the atmosphere with methane.
What are cows (cattle)?
There are 2 main categories of greenhouse gases: __________________ and _________________.
What are man-made and natural?
These important ecosystems would be threatened if dams were built to increase a growing populations' water supply.
What are wetlands?
These offer measurable pre-event data, compared to earthquakes, and can therefore be more accurately predicted.
What are volcanic eruptions?
An overflow of water to an area of land that is usually dry
What is a flood?
Agriculture adds to harmful emissions of nitrous oxide, NO2, by using synthetic and organic crop ______________.
What are fertilizers?
The gas primarily responsible for the warming of the planet is ____________________.
What is carbon dioxide?
A community faces a _______ shortage, because their local supply was polluted by a chemical company, and the natural earth cycle cannot replace it quickly enough for their daily demands.
What is water?
These can significantly decrease loss of life and property damage during a severe weather or natural hazard event.
What are Early Warning Systems?
a natural event or process that can cause damage to people, property, and the environment
What is a natural hazard?
Climate scientists refer to similarities in collected data as
What are trends?
Gases used in air conditioning and refrigeration that have High Global Warming Potential (GWP), because they trap thousands of times more heat per pound than carbon dioxide (CO₂).
What are fluorinated gases? HFCs, PFCs, SF6, NF3
What is the BEST thing humans can do to be good environmental stewards?
What is conserve water?
Scientists and engineers must consider tectonic plate boundaries when building structures that can withstand these powerful, and often unpredictable, natural hazards.
What are earthquakes?
What is a tsunami?
In a battle of CO2 emissions, which would win, a volcanic eruption or human fossil fuel usage?
What is human fossil fuel usage?
Produces about 10% of total U.S. greenhouse gas emissions and roughly 26% to one-third of global emissions through livestock digestion, crop fertilizers, and soil management
What is agriculture (corporate farming)?
Scientists can use these, collected at the Poles, to support human impact on the environment today vs. no human impact thousands of years ago.
What are ice cores?
