Climate Changes
What causes global warming?
As human activity takes place, carbon-dioxide is released. It could also be volcanic eruptions that releases CO2 in the atmosphere. It could also be the Earth's position in space.
Name the most common greenhouse gas
Carbon Dioxide
Name the most common way nature contributes to global warming.
When animals breathe they release Carbon Dioxide, livestock release of methane as a resutl of digestion
Or Depends on answer
What are two common ways of transportation that does not add to global warming?
Walking and Biking
What is the most abundant gas in our atmosphere?
Nitrogen
How do people cause climate change?
Humans use energy and release carbon dioxide into the air
What are greenhouse gases?
Gases trapped in the atmosphere
How do volcanoes contribute to global warming?
When they erupt, they release large amounts of Co2
How does planting trees help reduce carbon dioxide levels?
They take in Co2 and release oxygen via photosynthesis.
What is AQI an abbreviation for?
Air quality index.
How can earth's forests affect global warming?
The forests use the CO2 in the atmosphere to change into oxygen
How are animals affected by greenhouse gases?
Some animals can only live in cold temperatures and if temperature rises, they can become extinct

How are cold-water animal (polar bears) species responding to the increase of temperature in their waters?
Many of the species are dying off, migrating, and breaking patterns of life cycles.
What does the word "composition" mean?
What is it made of.
Name 4 Greenhouse gases
CO2, methane, water vapor, and nitrous oxide, Chlorofluorocarbons
How are green houses gases linked to global warming?
The green house gases get traped in the atmosphere therefore making the temperatures rise
How does the AQI help people?
Air quality index tells us how polluted the air is 24/7
What do CFC's and deforestation cause?
They cause global warming (extra greenhouse gases in the atmosphere).
How will climate change affect the ocean?
Polar Ice caps may melt therefore increasing ocean levels.
If we continued to damage the earth,how would that affect life?
The atmoshere would overheat and therefore lifeforms would not have enough time to adapt.
What are 2 alternatives for making electricty that do not contribute to global warming?
Wind and Hydropower
What are at least three evidences that global warming maybe happening?
Temperature changes in ocean, melting ice caps, arctic animals are dying, more hurricances, tornados and thunderstorms
What are 3 facts about carbon?
An element, abundant in our bodies, moves from living thing to living thing when eaten, in decaying animals and plants, can turn into fossil fuel over millions of years, atomic number is 6, atomic mass is 12.01, symbol is "C" and tons more
