False
True or False: Ozone is a greenhouse gas.
True
True or False: Species are gradually moving towards the poles due to climate change.
True
True or False: The climate impacts all populations and all communities.

Short Answer: What is green house gases?
Answer: Gases present in the Earth's atmosphere that reflect infrared radiation back to Earth, thus warming it. The most important ones affected by humans are carbon dioxide, methane, nitrous oxide, and chlorofluorocarbons. Water vapor also acts as a greenhouse gas.
Fill in the Blank: ______________ is the process in which the emission of infrared radiation by the atmosphere warms the planet's surface.
Answer: Greenhouse Effect
What are two major components of climate change?
Answer: Increasing temperature and changing precipitation
What form of energy is retained by Greenhouse Effect, and what are the top two contributing gases?
Answer: Infrared radiation; water vapor (36-70%) and CO2 (9-26%)
Short Answer: Where is the majority of the carbon found and how much carbon from earth is found there?
Answer: It is found in the oceans, and about 56% of all carbon is found there.
Name 2 climate factors that effect communities.
Answer: Precipitation, Temperature
What is an example of an invasion by disease causing organisms?
Answer: malaria parasite
Short Answer: What are the climate factors that impact all populations and communities?
Answer: temperature, rainfall, wind, solar radiation

Fill in the blank: Two examples of impacts that are caused by global warming are __________ and __________.
Possible Answer: Animals move closer to the poles. Disease parasites extend their range. Spring starts earlier causing plants to flower sooner.
True or False: As a result of global warming, diseases and vectors are extending their range.
True
True or False: C3 photosynthesis can be as efficient as C4 photosynthesis if carbon dioxide concentrations are high.
True
True or False: Global warming and [CO2] increase plant primary production
True
True or False: Global warming has been happening since the 1970s.
True
True or False: Global warming is expected to aid malarial spread to the United States.
True
True or False: Global warming is mainly due to higher [CO2] levels that are a result of burning fossil fuels and clearing forested land.
True
True or False: Greenhouse Effect is the process in which the emission of infra red radiation by the atmosphere warms the planet's surface.
True
True or False: The increase concentration of carbon in the atmosphere is helping C3 plants do just as well as C4 plants.
True
True or False: Water vapor is the most abundant greenhouse gases in Earth's atmosphere.
True
Short Answer: List three ways in which Global Warming is affecting life on earth?
1. Speeding flowering and breeding events 2. It is allowing animals to move towards the poles 3. Diseases and vectors are extending their range
Short Answer: What is the greenhouse effect?
Answer: A process in which the emission of infra red radiation by the atmosphere warms the planet's surface.
Which is NOT a way how an increase of the concentration of carbon dioxide will affect other factors of individual plant responses? A) Decrease in stomatal conductance B) C4 photosynthesis plants benefit and yield is increased C) Increase in reproductive output D) C3 photosynthesis plants benefit and yield is increased
Answer: B) C4 photosynthesis plants benefit and yield is increased
Which of these is not an effect climate change will have on the environment? A) Species moving towards the poles B) Species breeding later on in the spring C) Species breeding earlier on in the spring D) Malaria becoming more prevalent
Answer: B) Species breeding later on in the spring
Which of these is NOT a result of global warming? A) Speeding of flowering and breeding events B) Species are moving towards the poles C) CO2 concentrations are decreasing D) Disease and vectors are extending their range
