What happens when an oceanic plate collides with a continental plate Why does this happen?
When an oceanic and a continental plate collide, eventually the oceanic plate is subducted under the continental plate due to the high density of the oceanic plate. As time goes on the hot magma rising upward from the subduction zone causes further compression of the mountain belt.
What happens when an oceanic plate converges with a continental plate quizlet?
What happens when an oceanic plate converges with a continental plate? The oceanic plate is subducted. The two plates are forced upward, and a large mountain range is formed.
What are the consequences of convergent oceanic and continental plates?
Effects of a convergent boundary between an oceanic and continental plate include: a zone of earthquake activity that is shallow along the continent margin but deepens beneath the continent, sometimes an ocean trench forms immediately off shore of the continent, a line of volcanic eruptions a few hundred miles inland
What happens when a continental plate converges with another continental plate?
What happens when two continental plates collide? Instead, a collision between two continental plates crunches and folds the rock at the boundary, lifting it up and leading to the formation of mountains and mountain ranges.
What happens if oceanic plate continues to move downward?
= If the leading edge of Plate A continuously be moving downward, its leading edge will melt forming magma because beneath crust is the mantle. The mantle is also hotter than the crust.
What is the difference between oceanic plates and continental plates?
Oceanic plates are much thinner than the continental plates. At the convergent boundaries the continental plates are pushed upward and gain thickness. The rocks and geological layers are much older on continental plates than in the oceanic plates. The Continental plates are much less dense than the Oceanic plates.
What happens when two plates diverge?
The plates diverge and this causes the construction of new rock. It happens when two tectonic plates pull apart and rock from the mantle rises up through the opening to form new surface rock when it cools. It happens at the start of a new ocean and continues at the mid-ocean ridge while the ocean is opening.
Is continental or oceanic plate more dense?
Both oceanic crust and continental crust are less dense than the mantle, but oceanic crust is denser than continental crust. This is partly why the continents are at a higher elevation than the ocean floor. As a result, the rock that forms from that melt is less dense than the original rock.
What geologic feature is created when an ocean plate converges with another ocean plate?
Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. Volcanoes are one kind of feature that forms along convergent plate boundaries, where two tectonic plates collide and one moves beneath the other.
Why are convergent plate boundaries dangerous?
A convergent plate boundary, also known as a destructive plate boundary, usually involves an oceanic plate and a continental plate. The plates move towards one another and this movement can cause earthquakes. As the plates collide, the oceanic plate is forced beneath the continental plate.
What is an example of oceanic continental convergence?
Examples of ocean–continent convergent boundaries are subduction of the Nazca Plate under South America (which has created the Andes Mountains and the Peru Trench) and subduction of the Juan de Fuca Plate under North America (creating the Cascade Range).
What are examples of convergent boundaries?
Examples of continent-continent convergent boundaries are the collision of the India Plate with the Eurasian Plate, creating the Himalaya Mountains, and the collision of the African Plate with the Eurasian Plate, creating the series of ranges extending from the Alps in Europe to the Zagros Mountains in Iran.
What forms when two continental plates pull apart?
When two continental plates diverge, a valleylike rift develops. This rift is a dropped zone where the plates are pulling apart. As the crust widens and thins, valleys form in and around the area, as do volcanoes, which may become increasingly active.
What are the two continental plates?
two types of plates—oceanic and continental—which float on the surface of the Earth’s mantle, diverging, converging, or sliding against one another.
Do two colliding continental plates always cause volcanoes?
Volcanoes more often occur from the collision of an oceanic plate and a continental plate rather than two continental plates.
