This unit focuses on the study of earthquakes and volcanoes as a means for better understanding the dynamic Earth we live on; and the impact of catastrophic events on human life. The student should complete this unit with a greater understanding of Earth's dynamic nature, being able to scientifically explain the cause of earthquakes and volcanoes. Along with the science of volcanoes and earthquakes the student will appreciate the value of scientific study as it relates to the protection of human life and society. This unit is by no means an all inclusive look at all catastrophic events. The goal is an understanding of two types of catastrophic events that will enable the student to analyze other catastrophic, their scientific study and their impact on human life.
