Volcanoes usually occur along the line where two plates meet.
They are both caused by movement of tectonic plates.
Nearly all of them are located in chains stretching across the earth, often for many thousands of miles. Geologists believe that this distribution is related to a theory of the development of the earths surface called plate tectonics.
Plate tectonics is considered to be a unifying theory because a consensus finds it to be true. Most scientists believe the plate tectonics cause volcanoes and earthquakes.
Plate tectonics
Volcanoes are caused by the magma from the Earth's mantle; this magma is released through faults in the Earth's tectonic plates.
The theory of plate tectonics helps explain the location of earthquakes, as they frequently happen along fault lines.
it is connected because pacific theory is all about submarine volcanoes and when you say submarine volcanoes it means that........ volcanoes under the sea that's why volcanoes & pacific theory is related to each other...
Plate tectonics.
The theory of plate tectonics helps to explain how earthquakes and volcanic eruptions occur.
Continental drift, sea floor spreading, glacial striation, jigsaw fit of the continents, geological matches on different contintents (such as type of rock or fossil found) ,earthquakes, and volcanoes led to the theory of plate tectonics.
The unifying theory of geology is the theory of plate tectonics, which explains the movement of Earth's lithosphere (outer shell) through the interactions of large plates that float on the semi-fluid asthenosphere beneath them. This theory helps explain various geological processes such as earthquakes, volcanoes, mountain building, and the distribution of continents.
the theory explains how Earth's plates form and move. it also explains how plates interact ,producing volcanoes,mountain range ,earthquakes,and featurs of the ocean floor
