Earthquakes and Volcanoes Earthquakes and volcanoes are closely connected because both occur due to dynamic processes in the Earth’s crust. Earthquakes and volcanoes are separate geological events, but they often occur in close proximity to each other. The majority of earthquakes occur along plate boundaries. Volcanoes, on the other hand, result from the movement of molten rock, or magma, from the Earth’s mantle to the surface. Volcanic eruptions are commonly associated with convergent plate boundaries where two plates collide and one sinks below the other. When the plate sinks, it heats up and releases water and other substances that cause the overlaying mantle to melt. The magma rises to the surface under the pressure, and volcanoes are formed. The Pacific Ring of Fire is also the site of most of the world’s volcanic activity. The Taal volcano is one of the most active volcanoes in the Philippines. Volcanoes can cause earthquakes, and earthquakes can cause volcanic eruptions. The relationship between earthquakes
WEATHER WONDER
Did you know that earthquakes can occur within tectonic plates? These are called intraplate earthquakes and occur away from the boundaries.
