From “Donna O’Meara: The Volcano Lady” by McGraw Hill Education
"When Donna went back to school at the age of 32 to study science, her passion for volcanoes began. She took geology classes to learn more about what rocks and soil tell us about the earth. She found out that volcanism is one of the most dynamic forces in nature. Volcanoes constantly shape and change the earth. Many islands, such as the islands that make up Hawaii, were formed by volcanic activity."
