### Learning Outcomes

This chapter has several goals and objectives:

• Describe the causes of tectonic stress and how they influence earthquakes and volcanoes.
• Understand where earthquakes and volcanoes are located around the world and why.
• Explain geologic structures that lead to folding and faulting of the physical landscape.
• Determine how the composition of magma determines the explosiveness of the volcanic eruption.
• Describe the various types of fault lines and volcanoes and the landforms they form.

## Essential Questions

• Could humans live in places along the Wasatch Front without the Wasatch fault and the earthquakes it causes?
• How does plate tectonics explain where and why earthquakes and volcanoes occur where they do?
• What role do earthquakes and volcanoes have on civilization? What benefits do they bring us?
• How could understanding Earth’s tectonic forces help save lives?
• What beneficial roles do tectonic forces have ecologically and for humanity?
