Greenhouse Efect
Define the greenhouse effect?
A naturally occurring process where atmospheric gases trap infrared radiation (heat) reflected off the Earth's surface, keeping the planet warm enough to support life.
Name 2 greenhouse gases
- Chloroflourocarbons
- Methane
- Nitrous Oxide
What is climate change?
Describes a change in the average weather conditions in a region over aling period of time
Name 4 global solutions to global warming
- Kyoto protocol
- Carbon Trading
- Montreal Protocol
- REDD agreement
What are categories of effects of climate change?
Health,Extreme weather and Environment
What are the 4 steps to the greenhouse effect?
1. Solar radiation reaches earths atmoshpere some of this is relfected to space
2. The rest of the suns energy is absoebed,heating the earth
3. Heat readiates from earth towards space
4.Some heat gets trapped by greenhouse gases
What is the most damaging greenhouse gas?
Carbon dioxide
Describe the connection between climate change and global warning
Global warming is an effect of climate change
Explain why we need global solutions for global warming?
We need global solutions for global warming because the atmosphere is a shared, borderless resource, and emissions from any single country affect the entire planet
Explain how climate change negatively impacts ecosystems
Climate change damages ecosystems by altering temperatures, disrupting rainfall, raising sea levels, and changing ocean chemistry faster than plants and animals can adapt
Is the greenhouse effect inherently a bad thing? why or why not
It is not because, the greenhouse effect is a natural process.It keeps temperature warm so life can be sustained
Give 2 natural examples greenhouse gases and 2 human made examples of greenhouse gases
Natural - Watervapour(evaporation,plant respiration)
Natural - Methane(animal waste,livestock,wetlands)
Human made - CFC(fridges,aerosol)
Human made - C02(burning of fossil fuels)
Is climate change a bad thing?
Climae change has some advantages but the negative outweighs the positive
What is carbon trading?
a market-based system where companies, governments, or individuals buy and sell permits and credits that allow the emission of carbon dioxide or other greenhouse gases
eg. Company B is only allowed 30 emissions a year so the ask Company A for some of theirs
Give 2 examples of each category of climate change
Health: respiratory problems,disease from poor water availability
Extreme Weather: heatwave,more flooding,heavier drough
Environment: Ocean acidification,sea levels rising,shrinking ice sheets
Could we live on earth without the greenhouse effect?why or why not
We could not survive on Earth without the natural greenhouse effect. The earths average temperature would drop by 33 degrees celsius
How do greenhouse gases keep the earth warm?
They trap the heat
Explain 2 causes of climate change
Farming Livestock (Methane)
What is the kyoto protocol?
In short, the Kyoto Protocol operationalizes the United Nations Framework Convention on Climate Change by committing industrialized countries and economies to limit and reduce greenhouse gases emissions in accordance with agreed individual targets.
How have humans contributed to the greenhouse effect?
Human activities such as burning fossil fuels,agricultureetc are increasing the amount of greenhouse gases released into the atmosphere
Trapping extra heat: Earths temperature rises
What does (NT3) and (SF6) stand for?
NT3 - nitrogen triflouride
SF6 - sulfur hexafluoride
What is the difference between global warming and climate change?
Global warming is the long-term rise in Earth's average surface temperature, while climate change is a broader term that includes global warming and all its related side effects
What is the montreal protocol?
The Montreal Protocol on Substances that Deplete the Ozone Layer is the landmark multilateral environmental agreement that regulates the production and consumption of nearly 100 man-made chemicals referred to as ozone depleting substances
