Analyzing Historical Active Volcanoes by Country

This activity focuses on interpreting a bar graph that displays the number of historically active volcanoes across four countries. Participants will use the graph to answer questions about which country has the most historically active volcanoes and explore the relationship between the number of active volcanoes and volcanic eruptions in a given year. The guided practice encourages deeper engagement with the data, prompting participants to compare and analyze the quantities of volcanoes in different countries.

  1. EXAMPLE 1 Interpreting a Bar Graph Volcanoes The bar graph at the right shows the number of historically active volcanoes in four countries. Which country has the most historically active volcanoes?

  2. EXAMPLE 1 Interpreting a Bar Graph Use the bar graph above about volcanoes. Answer the question or explain why you can’t answer the question using the graph. a. Which country has the most historically active volcanoes? b. Which country has the most volcanic eruptions in a given year?

  3. EXAMPLE 1 Interpreting a Bar Graph SOLUTION a. The vertical axis in the bar graph is labeled Historically active volcanoes, so the tallest bar represents the country with the most historically active volcanoes. Because the United States has the tallest bar, it has the most historically active volcanoes. b. Having more historically active volcanoes doesn’t necessarily mean having more eruptions, so you can’t answer this question from the bar graph.

  4. ANSWER About 80 volcanoes for Example 1 GUIDED PRACTICE Use the bar graph above about historically active volcanoes. 1. About how many more historically active volcanoes does Chile have than Mexico?

  5. ANSWER Canada for Example 1 GUIDED PRACTICE Use the bar graph above about historically active volcanoes. 2. Which country has the least number of historically active volcanoes?

  6. ANSWER 215 volcanoes for Example 1 GUIDED PRACTICE Use the bar graph above about historically active volcanoes. 3. About how many historically active volcanoes do Canada, Mexico, and the U.S. have altogether?
