As human activity takes place, carbon-dioxide is released. A contributing factor are also be volcanic eruptions that releases carbon dioxide in the atmosphere.
100
Name one common greenhouse gas
Carbon Dioxide
100
Name the one way we contribute to global warming.
We release carbon dioxide when we breathe, other answers also acceptable
100
What are two common ways of transportation that does not add to global warming?
Walking and Biking
100
What is the most abundant gas in our atmosphere?
What is Nitrogen
200
How do people cause climate change?
Humans use energy and release carbon dioxide into the air
200
What are greenhouse gases?
Gases trapped in the atmosphere
200
How do volcanoes contribute to global warming?
When they erupt, they release large amounts of Co2
200
How does planting trees help reduce carbon dioxide levels?
They take in Co2 and release oxygen via photosynthesis.
200
Define smog?
Mix of air pollutants in atmosphere.
300
How can earth's forests affect global warming?
The forests use the CO2 in the atmosphere
300
How are animals affected by greenhouse gases?
Some animals can only live in specific temperature ranges and if temperature rises, they can become extinct
300
Why does deforestation occur?
To clear land for agriculture.
300
How are cold-water animal species responding to the increase of temperature in their waters?
Many of the species are dying off, migrating, and breaking patterns of life cycles.
300
Define ocean acidification?
When the oceans take up carbon dioxide, becoming more acidic in the process.
400
Name one additional effect of ocean acidification?
Organisms that create calcium based shells have a much harder time creating skeletons, leading to decreases in population and size.
400
How are green houses gases linked to global warming?
The green house gases get trapped in the atmosphere, reflecting heat back at the Earth, therefore making the temperatures rise
400
How do forests contribute to the removal of greenhouse gases?
They respirate by exchanging Co2 for oxygen
400
Name two ways to reduce your carbon footprint?
Recycling, eating less beef, driving eco friendly cars.
400
What do CFC's cause?
CFC's- depletion of ozone layer.
500
How will climate change affect the ocean?
Polar Ice caps may melt therefore increasing ocean levels, may disrupt ocean currents due to influx of cold fresh water.
500
If we continued to damage the earth, how would that affect life?
The earth would overheat and lifeforms would likely not have enough time to adapt.
500
What are 2 alternatives for making electricty that do not contribute to global warming?
Wind and Hydropower, solar, etc.
500
What is the evidence that global warming maybe happening?
Loss of biodiversity, stronger and more frequent storms, temperature rising rapidly.
500
Explain the process of eutrophication.
Nutrient imbalance, huge bloom of algae, algae die, large amount of oxygen required for decomposition, then mass mortalities.
