When two plates move apart from each other and the space that this creates is filled with new crustal material sourced from molten magma that forms below. When two oceanic plates converge, both a trench and a string of volcanoes are formed.
There are three plate boundaries convergent, divergent, and transform. Ridges Opposite of a convergent boundary, a divergent boundary is formed by the spreading of a tectonic plate.
Rift Valleys When divergent boundaries occur in continental plates, a different geological feature, called a rift valley, is formed. Ultimately, they will form the floor of a new ocean. There are seven plates. The lithosphere is broken up into what are called tectonic plates.
As these plates slowly move about, they interact with each other, forming boundary zones. Mount Saint Helens is an example of a volcano formed by an oceanic plate that is subducting under the North American continental plate.
At the surface, the topographic expression is commonly an oceanic trensch on the ocean side and a mountain range on the continental side. These depressions slowly fill with water, forming lakes, as their level drops.
Deep marine trenches are typically associated with subduction zones. Trenches Trenches are geological features formed by convergent boundaries.
Fault Lines A transform boundary connects two diverging boundaries, creating a fault line. The nature of a convergent boundary depends on the type of lithosphere in the plates that are colliding. The relative motion of the two plates.
When two tectonic plates converge, the heavier plate is forced downward, creating a subduction zone. The first one convergent occur when two plates slide towards each other commonly forming either a zone. Because of friction, the plates cannot simply glide past each other.
The origin of new divergent boundaries. When the plate being forced downward begins to melt, this magma rises to the surface, forming volcanoes. Sciencing Video Vault Volcanoes Another geological feature that results from a subduction zone is volcanoes.
This process feeds magma to the surface, creating new crust. Divergent zones in oceanic plates form a geological feature called a ridge, forced upward by the pressure of the rising magma.
Ultimately, this pressure causes large vertical and horizontal displacements, forming towering mountain ranges.
However, the most famous transform boundaries are found on land. Mountain Ranges When two continental plates converge, neither of the buoyant plates is able to give way and subduct beneath the other. Most transform boundaries are found on the ocean floor, where they often offset active spreading riges to form a zigzag plate boundary.
Divergent boundaries are when two plates slide apart from each other examples of which can be seen at mid-ocean ridges and active zones of riftingg. This line represents an area of shear, where two plates are moving horizontally against one another.
Whe a dense oceanic plate colldes with a less-dense continental plate, the oceanic plate is typically thrust underneath because of the greater buoyancy of the continental lithosphere, forming a subduction. An example of this type of geological feature is the East African Rift Zone.
The Marianas Trench is an example of a trench formed by the convergence of two oceanic plates. Because of friction and heating of the subducting slab, volcanism is almost always closely linked.
The third one is transform boundaries are when plates slide or, grind past each other along transform faults.Topographical Features at Divergent and Convergent Plate Margins Essay Essay Question 1: Compare and contrast the topographical features at divergent and convergent plate margins.
