Q:

Where does subduction take place?

A:

Quick Answer

Subduction is a geological process that takes place at the boundaries between tectonic plates in which one plate is forced underneath another. Subduction occurs when the massive pressures of entire continental or oceanic tectonic plates collide, over the course of millennia, and one slowly is subsumed underneath the other.

Full Answer

Subduction often results in spectacular natural geographic phenomena. Geological subduction is exemplified by the Himalayan Mountains, the earthquakes of the American Pacific coast and the volcanic activity that gave rise to the island of Japan. Subduction is one of the most immense physical processes on Earth, shaping the face of the Earth itself.

  • Q:

    What happens at a transform boundary?

    A:

    Tectonic plates move horizontally past one another at transform boundaries in either strike-slip or aseismic motions. Earthquakes and tsunamis occur when the pressure locking plates in a strike-slip boundary releases suddenly. Volcanic activity, while common at convergent and divergent plate boundaries, is rare at transform borders.

  • Q:

    What are the eight minor plates?

    A:

    The earth's surface is divided up into seven major and eight minor tectonic plates. The minor plates consist of the Caribbean plate, the Arabian plate, the Juan de Fuca plate, the Nazca plate, the Scotia plate, the Philippine plate, the Cocos plate and the Indian plate. Due to its size and the significant amount of land on it, some scientists consider the Indian a major plate instead.

  • Q:

    What is the definition of plate boundaries?

    A:

    Plate boundaries are locations where two tectonic plates meet. There are three different types of plate boundaries, which are defined by the type of motion occurring at the boundary. Some boundaries are located within continents of land, while others are located under oceans.

  • Q:

    What is the place where two plates move together?

    A:

    Areas where tectonic plates make contact with each other are known as convergent boundaries. Collisions between two plates are very slow, with movement of only a few centimeters per year occurring at the convergent boundaries.
