It explains how high-viscosity lava leads to explosive eruptions, while low-viscosity lava flows create distinct formations. Key factors for predicting volcanic activity include seismic events near volcanoes, gas emissions, and ground deformation.

Eruptions result from melting mantle rock and vary based on magma composition, impacting the environment. They can be effusive or explosive, with supervolcanoes like Yellowstone posing significant threats.

It highlights the difficulties in the theory's acceptance due to lack of a driving mechanism for continental movement and geographic biases among early 20th-century geologists. The text also outlines learning objectives related to understanding different plate boundaries, the driving forces behind plate movements, and California's plate boundaries.

It discusses Alfred Wegener's continental drift theory, evidence supporting it, and the mechanism of seafloor spreading. The text describes types of tectonic plate boundaries: divergent (mid-ocean ridges), convergent (subduction and mountain formation), and transform (like the San Andreas Fault).

It details the types of tectonic stress, the mechanisms behind earthquakes at different plate boundaries, and emphasizes the significance of fault lines and seismic waves. Notable earthquakes are mentioned to illustrate these concepts. The text underscores the importance of construction quality and preparedness measures to minimize damage and fatalities in earthquake-prone areas.
