Volcanoes and earthquakes

• According to the theory of plate tectonics, Earth is an active planet. Its surface is composed of many individual plates that move and interact, constantly changing and reshaping Earth’s outer layer. Volcanoes and earthquakes both result from the movement of tectonic plates.
• The zones along plate boundaries are the most geologically active regions on Earth. Earthquakes are common along all types of boundaries and occur all over the world; volcanoes are generally associated with divergent and convergent boundaries. One of the most well-known plate boundaries encircles the Pacific Ocean, and the frequent earthquakes and volcanic activity along this circle of boundaries have caused it to be dubbed the Ring of Fire.
