Thus at divergent boundaries, oceanic crust, made of basalt, is created. When two plates come together, it is known as a convergent boundary. The impact of the two colliding plates buckles the edge of one or both plates up into a rugged mountain range, and sometimes bends the other down into a deep seafloor trench.

A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, lava spews from long fissures and geysers spurt superheated water. Frequent earthquakes strike along the rift. Beneath the rift, magma—molten rock—rises from the mantle.

A transform boundary is where plates slide past each other. with no creation or destruction of lithosphere. Plate Margin Examples. There are three general types of plate boundaries: divergent, convergent, and transform. Each general type has multiple. ‘species’: divergent boundaries can be spreading ocean ridges or. continental rift zones; convergent boundaries can occur between. two continental plates.

The new theory extends the theory of plate tectonics - a kinematic description of plate motion without reference to the forces behind it - with a dynamical theory that provides a physical explanation for both the motions of tectonic plates as well as motion of plate boundaries.

Plate tectonics theory describes how the lithosphere of the. Earth is broken into various plates. These plates drift on the. asthenosphere at very slow rates. As plates move away from. each other the lithosphere thins and tears. At these divergent. plate boundaries new oceanic lithosphere is created in the.

Current Major Plates. Plate tectonics, from Greek builder or mason, is a theory of geology that has been developed to explain the observed evidence for large scale motions of the Earth's lithosphere.

There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. This image shows the three main types of plate boundaries: divergent, convergent, and transform. Image courtesy of the U.S. Geological Survey.

Three types of plate boundaries exist, with a fourth, mixed type, characterized by the way the plates move relative to each other. They are associated with different types of surface phenomena. The different types of plate boundaries are:

Where the plates meet, their relative motion determines the type of boundary: convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries. The relative movement of the plates typically ranges from zero to 100 mm annually.

As the MORE DENSE oceanic plate (OP) subducts under. the less dense plate (CP or OP), it pulls the front edge. of the less dense plate down, creating a deep ‘zone’. (TRENCH). Illustration of what is happening. Landform: VOLCANOES. Plate Boundary: CONVERGENT.

what type of boundary is created when two tectonic plates pull apart?
A divergent boundary is created when two tectonic plates pull apart.
