Name:Per.:Date:Mass Extinctions on Earth over TimeObjective: Identify the timing of mass extinctions and the causes of massextinctions.Part 1: Identifying Mass Extinctions on a GraphDirections: IDENTIFY and LABEL each mass extinction you see on yourgraph. Write the approximate time of each mass extinction on the graph whereit occurs. Write the name of each mass extinction on the graph (“PermianTriassic” for example). You will determine the names through yourresearch.Part 2: Internet ResearchBBC's NATURE: The Big 5 Extinctions: http://www.bbc.co.uk/nature/extinction eventsUse this article to research the possible causes of specific mass extinctions.BBC's NATURE: Mass Extinction Causes http://www.bbc.co.uk/nature/extinction causesUse this article to research HOW methane release, flood basalts, climate change, and impact events causeextinctions.Select ONE of the mass extinctions you identified to research. Yourresearch should include the following details:1. Name of extinction and when it happened2. What percentage of species went extinct (Overall, Marine, and/orTerrestrial).3. Identify the types of species that were most negatively affected.4. What was the cause or causes of each mass extinction? Providedetails on how these causes actually caused species to goextinct (Ex: How do flood basalts cause extinctions?) Summarize your research in paragraph form (Topic sentence,details, closing sentence). Summaries should incorporateresearched facts and details.

as the 'sixth mass extinction'1,2. With three short words, we place the biotic and environmental disturbance created by mankind on par with the greatest biodiversity crises of the past half billion years. This is a comparison that demands close attention as the 'Big Five' mass extinctions

guild. Second, real-world patterns of animal extinctions are generally nonrandom (28, 29) and may produce weaker or stronger effects on ecosystem processes than randomly ordered loss of species (24-27, 30). We evaluate declines in nutrient recycling predicted from the following known correlates of
