Topographical features at divergent and convergent

Ecofeminism and ecopsychology are mentioned, for example, as are terms from organic gardening and permaculture. Because the life sciences messily overlap that's lifeterms from botany, biology, geology, chemistry, meteorology, and agriculture are included as well.

Topographical features at divergent and convergent

As these plates slowly move about, they interact with each other, forming boundary zones.

Topographical features at divergent and convergent

Each of these different types of plate boundaries produces unique geographical features on the surface, including fault lines, trenches, volcanoes, mountains, ridges and rift valleys. Fault Lines A transform boundary connects two diverging boundaries, creating a fault line.

This line represents an area of shear, where two plates are moving horizontally against one another. Trenches Trenches are geological features formed by convergent boundaries. When two tectonic plates converge, the heavier plate is forced downward, creating a subduction zone.

This process results in the formation of a trench. The Marianas Trench is an example of a trench formed by the convergence of two oceanic plates.

The deepest part of this trench, called the Challenger Deep, is over 36, feet deep, deeper than Mount Everest is tall. Sciencing Video Vault Volcanoes Another geological feature that results from a subduction zone is volcanoes.

When the plate being forced downward begins to melt, this magma rises to the surface, forming volcanoes. Mount Saint Helens is an example of a volcano formed by an oceanic plate that is subducting under the North American continental plate.

When two oceanic plates converge, both a trench and a string of volcanoes are formed. These volcanoes can build to produce island chains, such as the Mariana Islands, which are located alongside the Marianas Trench.

GIS techniques and technology

Mountain Ranges When two continental plates converge, neither of the buoyant plates is able to give way and subduct beneath the other. This results in a powerful collision that produces tremendous, crushing pressure. Ultimately, this pressure causes large vertical and horizontal displacements, forming towering mountain ranges.

The Himalayas, one of the tallest mountain ranges in the world, is an example of a geological feature that is formed when continental plates collide. Ridges Opposite of a convergent boundary, a divergent boundary is formed by the spreading of a tectonic plate.

This process feeds magma to the surface, creating new crust.

Plate tectonics - Wikipedia

Divergent zones in oceanic plates form a geological feature called a ridge, forced upward by the pressure of the rising magma. The Mid-Atlantic Ridge is an example of an oceanic divergent boundary formation. Rift Valleys When divergent boundaries occur in continental plates, a different geological feature, called a rift valley, is formed.

These depressions slowly fill with water, forming lakes, as their level drops. Ultimately, they will form the floor of a new ocean. An example of this type of geological feature is the East African Rift Zone.Divergent plate boundaries are where two plates are moving apart from one another (Ritter, ).

The topographic features that develop at this boundary are due to extension of the plate boundaries which causes rifting in continental and oceanic crusts (Strahler, , ).

Video: Plate Boundaries: Convergent, Divergent, and Transform Boundaries In the theory of plate tectonics, the earth's crust is broken into . Plate tectonics (from the Late Latin tectonicus, from the Greek: τεκτονικός "pertaining to building") is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates of the Earth's lithosphere, since tectonic processes began on Earth between 3 and billion years model builds on the concept of continental.

Oceanic trenches are topographic depressions of the sea floor, relatively narrow in width, but very long. These oceanographic features are the deepest parts of the ocean floor.

Relating information from different sources

Oceanic trenches are a distinctive morphological feature of convergent plate boundaries, along which lithospheric plates move towards each other at rates that vary from a few millimeters to over ten centimeters per year. GIS cadastral map with multiple layers.
