To calculate: To order the volcano eruption rates from greatest to least eruption rate
Answer to Problem 21PT
Volcanoes are arranged in order of greatest to least eruption rates:
Volcano | Date | Eruption rate |
Bezymianny | 1956 | |
Santa Maria | 1902 | |
Agung | 1963 | |
Mount St. Helens | 1980 | |
Hekla | 1947 | |
Helka | 1970 | |
Naguruhoe | 1975 |
Explanation of Solution
Given information: Table showing the greatest amounts of lava in cubic meters per second that erupted from six volcanoes:
Volcano | Date | Eruption rate |
Mount St. Helens | 1980 | |
Naguruhoe | 1975 | |
Helka | 1970 | |
Agung | 1963 | |
Bezymianny | 1956 | |
Hekla | 1947 | |
Santa Maria | 1902 |
Calculation:
Converting the eruption rates into standard form
Case1: Mount St. Helens in year 1980
Converting
Case2: Naguruhoein year 1975
Converting
Case3: Helkain year 1975
Converting
Case4: Agungin year 1963
Converting
Case5: Bezymiannyin year 1956
Converting
Case6: Heklain year 1947
Converting
Case7: Santa Mariain year 1902
Converting
Now, arranging in order of greatest to least eruption rate
Volcano | Date | Eruption rate |
Bezymianny | 1956 | |
Santa Maria | 1902 | |
Agung | 1963 | |
Mount St. Helens | 1980 | |
Hekla | 1947 | |
Helka | 1970 | |
Naguruhoe | 1975 |
Conclusion:
Hence, volcanoes are arranged in order of greatest to least eruption rates.
