What happens when two continental plates transform? When oceanic or continental plates slide past each other in opposite directions, or move in the same direction but at different speeds, a transform fault boundary is formed. No new crust is created or subducted, and no volcanoes form, but earthquakes occur along the fault.
What happens when two continental plates crash into each other?
When two plates carrying continents collide, the continental crust buckles and rocks pile up, creating towering mountain ranges. When an ocean plate collides with another ocean plate or with a plate carrying continents, one plate will bend and slide under the other. This process is called subduction.
What happens when an ocean plate collides with a continental?
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 is it called when two continental plates collide?
They are also known as destructive boundaries as rock is lost and melted in the process. The two plates must be an oceanic plate and a continental plate. When the two plates collide, a process called subduction occurs. What happens when two continental plates collide quizlet?
What happens when 2 continental plates converge?
When two continental crusted plates converge, they eventually collide and end up producing mountains; this was how the Himalayan Mountains were created. Neither continental crust will subduct underneath one another because of their similar densities.
What happens when 2 continental plates diverge?
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 happens when transform plate boundaries move?
The grinding action between the plates at a transform plate boundary results in shallow earthquakes, large lateral displacement of rock, and a broad zone of crustal deformation. Perhaps nowhere on Earth is such a landscape more dramatically displayed than along the San Andreas Fault in western California.
What is the effect of continental continental convergence?
Effects found at a convergent boundary between continental plates include: intense folding and faulting, a broad folded mountain range, shallow earthquake activity, shortening and thickening of the plates within the collision zone.
What is formed in a transform boundary?
The Earth's crust is split into sections called tectonic plates. Transform boundaries are where two of these plates are sliding alongside each other. This causes intense earthquakes, the formation of thin linear valleys, and split river beds.
What is formed when two plates are moving apart?
Mid-Ocean Ridges and Rift Valleys As the plates move apart, new cracks open in the solid rock. More molten material rises and hardens. The growing ridge stands high above the sea floor.
What is the result of the movement of transform fault?
Transform faults specifically accommodate lateral strain by transferring displacement between mid-ocean ridges or subduction zones. They also act as the plane of weakness, which may result in splitting in rift zones.
How do plates move at transform plate boundaries?
At transform boundaries, plates move past each other. This is one of the most common causes of earthquakes. At convergent boundaries, plates move toward each other. They can push together and cause mountain ranges to form.
What geologic events occur along two continental convergent plates?
A convergent plate boundary is a location where two tectonic plates are moving toward each other, often causing one plate to slide below the other (in a process known as subduction). The collision of tectonic plates can result in earthquakes, volcanoes, the formation of mountains, and other geological events.
What is the major geologic feature formed by the convergence of two continental plates?
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.
What is often formed when two continental plates collide?

Why do volcanoes form when continental plates collide?
When a continental and an oceanic plate collide, the oceanic plate slides underneath the continental plate, which leads to the formation of volcanoes due to the rocks in the oceanic plate turning to magma as they are sucked deeper into the earth. This happens due to the fact that oceanic plates are denser than continental plates.
What type of collision occurs when a sea or ocean between the two slowly shrinks until it fully disappears answer
This type of continental collision occurs when a sea or ocean between the two slowly shrinks until it fully disappears and the continents join together to form a large mountain range. Before it collided with the Eurasian plate, the Indian subcontinent was actually an island located on its own tectonic plate.
What happens when the plates grind at the transform plate boundary?
The grinding action between the plates at a transform plate boundary results in shallow earthquakes, large lateral displacement of rock, and a broad zone of crustal deformation. Perhaps nowhere on Earth is such a landscape more dramatically displayed than along the San Andreas Fault in western California.
Why are transform plate boundaries called transform plate boundaries?
Such boundaries are called transform plate boundaries because they connect other plate boundaries in various combinations, transforming the site of plate motion.
What plate boundary is the Pacific Plate?
The Pacific Plate slides north-northwestward past the North American Plate along the San Andreas Transform Plate Boundary. The San Andreas Fault is responsible for most of the movement in western California, causing a sliver of the state to slide past the rest of the continent. In Mexico, a combinatiion of divergent and transform plate boundary motion is opening the Gulf of California, causing the Baja Peninsula to separate from the rest of Mexico.

Norton & Comp., New York.#N#Point Reyes National Seashore, Golden Gate National Recreation Area, and Pinnacles National Park present landscapes affected by the main line of movement, the San Andreas Fault. Channel Islands National Park, Santa Monica Mountains National Recreation Area and Joshua Tree National Park are within the Transverse Ranges, a block of crust that rotated as a result of the shearing motion. Cabrillo National Monument south of San Diego also lies within the broad zone of deformation between the two plates.#N#The transform plate boundary between the Pacific and North American Plates in western California formed fairly recently. About 200 million years ago, a large tectonic plate (called the Farallon Plate) started to subduct beneath the western edge of North America. This resulted in a line of volcanoes stretching all the way from what is now Alaska to Central America. Beginning about 30 million years ago, so much of the Farallon Plate was consumed by subduction that the Pacific and North American plates were in contact, forming the San Andreas transform plate boundary in western California. Over time, the San Andreas transform plate boundary has grown longer as the Farallon Plate split into two separate plates—the Juan de Fuca Plate on the north, and the Cocos Plate on the south. Remnants of the ancient volcanic mountain chain remain. In central and southern California, for example, the volcanoes have largely eroded away and massive areas of granite from the cooled magma chambers form portions of the Sierra Nevada Mountains, including Yosemite National Park.
What plate formed between the Pacific and North American plates?
Forty million years ago, a large tectonic plate, known as the Farallon Plate, was between the Pacific and North American plates. Subduction of the Farallon Plate beneath the entire West Coast created a line of volcanoes from Alaska to Central America.
What plate is the Virgin Islands in?
Carribean Tectonic Map. The Virgin Islands are in a broad zone where the landscape is being sheared up as the Carribean Plate slides eastward past the oceanic part of the North American Plate. Active volcanoes of the Lesser Antilles Island Arc form as the North American Plate subducts beneath the Caribbean Plate.
Which plate boundary formed between the Pacific and Pacific plates?
As the mid-ocean ridge separating the Farallon and Pacific Plates entered the subduction zone, the Farallon Plate separated into the Juan de Fuca and Cocos Plates. A transform plate boundary developed where the Pacific Plate was in contact with the North American Plate and the volcanism ceased in central California.
Which plate boundary formed during the West Coast tectonic evolution?
West Coast Tectonic Evolution. The San Andreas Transform Plate Boundary developed within the past 40 million years as a large portion of the Farallon Plate was subducted and the Pacific Plate made contact with the North American Plate in the California region.
Answer
When continental plates collide, mountains form. The least understood of all tectonic boundaries, continental plates have greater density, sometimes reaching lower than the mantel.
Answer
The collision of two continental plates results in the sandwich pattern, in which the plates pushes one another in the upward direction, giving rise to the formation of huge mountain ranges. The rocks are highly folded and faulted here due to the immense compressional force. This type of plate motion results in the earthquakes of various magnitude.
