Explain when each species became extinct and the suspected reason(s) that led to the extinction.
The first part of this assignment requires that you consider the history of extinction on our planet.
From the Sam Noble Museum, answer the following questions:
How many major mass extinction periods are listed here?
What caused each, and which major groups of species disappeared from each period?
Conduct a library or web search and find two examples of an extinct species (can be plant, animal, insect).
Explain when each species became extinct and the suspected reason(s) that led to the extinction.
Global Climate Change
Scientists have concerns that human activities are changing our environment at rapid rates that could result in a sixth mass extinction. Let’s examine the evidence:
Define greenhouse effect. Describe which gases are important to the greenhouse effect.
What were listed as human activities related to greenhouse gas production from each link?
How do humans contribute to both climate change and major extinction events?
What specific evidence do they site for this possible event? (you may need to conduct additional research to support your findings).
