Lesson 7.1 - Volcanoes and Plate Boundaries

Most volcanic activity occurs at divergent or convergent plate boundaries. However, some hot spots form away from plate boundaries (i.e, the Hawaiian Islands).

Lesson 7.2 - Volcanic Eruptions and Features

The way a volcano erupts is controlled by the composition of the magma, the amount of dissolved gas, and its temperature. These factors also affect the viscosity and flow of lava, which result in different volcanic features.

Lesson 7.3 - Hazards of Volcanic Eruptions

Gas emissions, lahars, and pyroclastic flows are some hazards that result from volcanic eruptions.
