* Convergent Plate Boundaries: Where tectonic plates collide. This can result in one plate sliding under the other (subduction), causing magma to rise and form volcanoes, or mountains to buckle upwards and trigger earthquakes. Examples include the Pacific Ring of Fire, the Himalayas, and the Andes Mountains.
* Divergent Plate Boundaries: Where tectonic plates move apart. This creates space for magma to rise from the mantle, leading to volcanic activity. Examples include the Mid-Atlantic Ridge and the East African Rift Valley.
Other Areas of Volcanic and Seismic Activity:
* Hotspots: Areas of unusually hot mantle plumes that can cause volcanic activity even in the middle of tectonic plates. Examples include the Hawaiian Islands and Yellowstone National Park.
* Transform Plate Boundaries: Where tectonic plates slide past each other horizontally. This can cause earthquakes but not usually volcanic activity. Examples include the San Andreas Fault in California.
Note: While the majority of volcanic and seismic activity occurs along plate boundaries, there are some exceptions. For example, hotspots can be found far from plate boundaries.
