part 1. Please read the instructions carefully. Please do not copy and paste graphs and/or text from website. You will not receive credit for copying and pasting.
FAQs:
Do I need to use data sets that are related to environmental science? => It is preferred, but it is not mandatory.
Can I use one data set to create all four graphs? => No. You need four different data sets.
Where do I collect data sets from? => You can collect them from any legitimate website such as United States Geological Survey.
I don’t even know where to begin. => No worries. Start with focusing on one graph at a time. If you are starting with a line graph, think about how line graphs are used and try to create one.
part 2.
In this lab, we are going to take a closer look at volcanoes. use this link
https://www.ngdc.noaa.gov/hazel/view/hazards/volcano/event-search)
For questions 1-5.
1. Volcanic Explosively Index (VEI) describe the size of explosive eruptions. Click on “VEI” on the table to read the description. Which volcanic eruption was the largest? What type of volcano is it?
2. Classify the volcanic eruptions based on its type (caldera, shield volcano, and stratovolcano) and calculate the average number of deaths.
Type Ave. number of deaths
Caldera
Shield volcano
Stratovolcano
3. Create a bar or column graph that shows the volcano type and average number of deaths.
4. Mt. Kilauea is a shield volcano, while Mount Saint Helens is a stratovolcano. Is the data consistent with typical eruptive behaviors of these two types volcanoes? Briefly explain.
5. Comment on the average number of deaths from Caldera. Is this number lower or higher than you would expect? Explain your reasoning.
For questions 6.-20. Go back to the data base and set the following two volcanic parameters and click the Search button.
Year min: 1900 max: 2020 Volcano Name Aso
6. How big of an eruption would you expect in the future? Briefly explain.
7. Is the Aso volcano due for an eruption or not? Explain your reasoning.
8. Briefly explain the usefulness of geologic history in hazard preparedness.
9. List causes of fatalities in the past 120 years (look under Agent column).
