- In the United States, where do volcanoes like the one shown in diagram C occur?
- Three quarters of dry land on earth is covered by which type of rock?
- A major concentration of earthquakes and composite volcanoes that runs through the Mediterranean Sea, crosses the Mideast and the Himalaya, and passes through the East Indies.
- Steep-sided dome- or spine-shaped mass of volcanic rock; are extremely high viscosity, degassed, felsic lavas (often glassy, for example, obsidian)
- Approximately 1,500 potentially ... volcanoes worldwide
- are volcanic depression at least 1 km in diameter• Result from very violent eruptions.• Crater Lake in Oregon is an example.A volcanic depression much larger than the original crater.
- New crust is created from rising magma at plate boundary 3
