Region along the plate boundary where one plate moves under another plate. Lithosphere Outer layer of earth made up of the upper part of the mantle and the crust.

There are three types of lithospheric plate boundaries: divergent (where lithosphere and oceanic crust is created at mid-ocean ridges), convergent (where one lithospheric plate sinks beneath another and returns to the mantle), and transform (where two lithospheric plates slide past each other).

This fracture can be seen beneath the ocean as a line of ridges that form as molten rock reaches the ocean bottom and solidifies. Plate Tectonics—the theory supported by a wide range of evidence that considers the earth’s crust and upper mantle

melt rises to form volcanoes. (Ex. the Aleutian Islands.) Oceanic-Continental convergence—An oceanic plate converges on a continental plate and the denser crust of the oceanic plate sinks beneath the more-bouyant continental plate. In this type of convergence, trenches, strong, destructive earthquakes and the rapid uplift of mountain ranges are

boundaries where plates are moving toward each other, and sometimes one plate sinks (is subducted) beneath another. The location where the sinking of a plate occurs is called a subduction zone. 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

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. gaps from upwelling magma from the mantle.

Oceanic trench. The oceanic trenches are hemispheric-scale long but narrow topographic depressions of the sea floor. They also are the deepest parts of the ocean floor. Trenches define one of the most important natural boundaries on the Earth’s solid surface, that between two lithospheric plates.

a trench is formed. (Example: The Marianas Trench, the Challenger Deep, at the southern end of the Marianas Trench, plunges deeper into the Earth’s interior (nearly 11,000 m) than Mount Everest, the world’s tallest mountain, rises above sea level (about 8,854 m).) Inboard of the overlying plate a volcanic arc forms.

Plates moving away from each other to form rifts and mid-ocean ridges. Convergent boundary Plates moving toward each other and colliding to form ocean trenches, mountain ranges, volcanoes and island arcs. Divergent boundary North American and Eurasian plates at the Mid-Atlantic Ridge is a example of what boundary?

At what type of boundary do deep-ocean trenches form? It began breaking up. According to Wegener, what happened about 200 million years ago to the super continent Pangea?

what boundary do trenches form
Trenches define one of the most important natural boundaries on the Earth’s solid surface, that between two lithospheric plates. Trenches form boundaries on the Earth’s solid surface between two lithospheric plates.
