What would happen if the rate of seafloor spreading is faster than the rate of seduction?
What would happen if the rate of seafloor spreading was faster than the rate of subduction? The Earth would grow larger.
What happens when one plate goes under another?
Plates Subduct 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. A deep ocean trench forms at this subduction boundary.
When two continents are pushed together at a convergent boundary the result is?
When two continental plates converge, they smash together and create mountains. The amazing Himalaya Mountains are the result of this type of convergent plate boundary.
Which of the following best describes the distribution of earthquakes?
Which of the following best describes the distribution of earthquakes around the globe? They occur in distinct zones. The map below depicts the locations of earthquakes in the ocean basins.
Why does the oceanic crust sink beneath the continental crust at a subduction boundary?
Because ocean crust is more dense than continental crust, it will sink beneath continents if tectonic forces push the oceanic crust into the continent.
Which plate boundary has a subduction zone?
convergent plate boundaries Subduction zones are where the cold oceanic lithosphere sinks back into the mantle and is recycled. They are found at convergent plate boundaries, where the oceanic lithosphere of one plate converges with the less dense lithosphere of another plate.
What process occurs along transform fault 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.
What type of plate boundary is established between India and the Eurasian plate?
Typically, a convergent plate boundary—such as the one between the Indian Plate and the Eurasian Plate—forms towering mountain ranges, like the Himalaya, as Earth's crust is crumpled and pushed upward.
What type of convergent plate boundary triggers the formation of active volcanoes as magma rises beneath the surface?
Subduction zones Subduction zones have a lot of intense earthquakes and volcanic eruptions. The subducting plate causes melting in the mantle above the plate. The magma rises and erupts, creating volcanoes.
What is a transform plate boundary quizlet?
Transform Boundary. A boundary where the two plates slide against each other in a sideways motion. As two plates slide past one another, neither plate is added to at the boundary, or destroyed.
How does plate tectonics explain the distribution of earthquake epicenters active volcanoes and major mountain belts?
According to the theory of plate tectonics, the Earth's outer shell (lithosphere) is made up of seven large and many smaller moving plates. As the plates move, their boundaries collide, spread apart or slide past one another, resulting in geological processes such as earthquakes, volcanoes and mountain making.
What plate boundary is associated with volcanic island arcs?
oceanic-continental convergent plate boundary When two oceanic plates collide against each other, the older and therefore heavier of the two subducts beneath the other, initiating volcanic activity in a manner similar to that which occurs at an oceanic-continental convergent plate boundary and forming a volcanic island arc.
Why does earthquake occur in subduction zone ?( The area where subduction occur?
Why do so many earthquakes originate in this region? The belt exists along boundaries of tectonic plates, where plates of mostly oceanic crust are sinking (or subducting) beneath another plate. Earthquakes in these subduction zones are caused by slip between plates and rupture within plates.
How are folded mountain belts like the Himalayas formed?
Fold mountains are created where two or more of Earth's tectonic plates are pushed together. At these colliding, compressing boundaries, rocks and debris are warped and folded into rocky outcrops, hills, mountains, and entire mountain ranges. Fold mountains are created through a process called orogeny.
Which plate boundary and movement commonly create non volcanic mountains explain how non volcanic mountains are created by plate tectonics?
Answer and Explanation: The convergent boundary is one where the impact of the two plates towards one another results in the formation of non-volcanic mountains.
How did the Himalayan mountains form quizlet?
The Himalayas were formed due to the collision between the Eurasian Plate and the Indian Plate. When Asia and Europe collided, subduction stopped because India could not sink into the mantle. Since it could not sink, the Indian Plate pushed the crust upward and also downward, because of this, the Himalayas were formed!
What is a deep valley that forms where an oceanic plate collides with a continental plate?
A. Trench is formed on the oceanic side when oceanic and continental crust collide. Explanation: … At the subduction boundary a deep ocean trench forms.
What causes the force that pushes magma from the magma chamber through the pipe and vent of a volcano gravity water flow expanding gases convergent boundaries?
When a volcano erupts, the force of the expanding gases pushes magma from the magma chamber through the pipe until it flows or explodes out of the vent.
Which type of basin forms at divergent boundaries rift?
A divergent plate boundary on land rips apart continents (Figure below). When plate divergence occurs on land, the continental crust rifts, or splits. This effectively creates a new ocean basin as the pieces of the continent move apart.
What is the motion of ridge trench transform fault?
A transform fault is a plate boundary along which the relative motion between the two plates is parallel to the strike of the fault and is geometrically the arc of a small circle about the pole of rotation between two plates.
How do you describe the location of earthquake epicenters active volcanoes and moving plates in the Pacific Ring of Fire *?
Answer: The Ring of Fire also referred to as the Circum-Pacific Belt is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes. … Along much of the Ring of Fire plates overlap at convergent boundaries called subduction zones.
What is the origin of the volcanoes in the Lesser Antilles and Central America?
Mountains formed in Central America and Lesser Antilles by plate collisions (subduction). Volcanoes formed islands and mountains. Coral reefs, uplifted by tectonic collisions, became islands.
How are continental rift magmas and continental arc magmas different?
Continental arc magmas are more viscous than continental rift magmas.
Why do geological activities such as earthquake volcanism and mountain formation happen to be confined on certain places around the globe?
Geologic processes such as plate tectonics impact the entire surface of the planet and have major influences on the location of natural hazards like earthquakes and volcanoes. So far, we have only studied large scale patterns in plate tectonics.
Which describes the boundary where earthquake activity occurs along rift valleys?
Divergent boundaries – where two plates are moving apart. Divergent boundaries within continents initially produce rifts, which produce rift valleys.
Why do earthquakes and volcanic eruptions occur along plate boundaries?
Tectonic plates are extremely large and can encompass both land and ocean. These tectonic plates interact with one another because of the Earth's internal heat. This heat causes movement of material beneath the Earth's crust and releases energy in the form of earthquakes and volcanic eruptions.
How the convection current affects the movement of tectonic plates?
Convection currents drive the movement of Earth's rigid tectonic plates in the planet's fluid molten mantle. In places where convection currents rise up towards the crust's surface, tectonic plates move away from each other in a process known as seafloor spreading (Fig. 7.21).
How did the Mauryan and Mughal empires bring religious diversity to India?
The Mauryan and Mughal empires brought religious diversity to India by introducing Buddhism and Islam. As the Mauryan empire flourished, its leader, Asoka, began studying Buddhist nonviolent teachings and built many stupas. This brought Buddhism to India.
What does convection ridge push and slab pull work together?

How plate tectonics lead to the formation of the Great African rift valley?
Millions of years ago, the Arabian Peninsula was connected to Africa. Seafloor spreading caused the Arabian and African plates to rift apart. The Indian Ocean flooded the rift valley between the continents, creating the Red Sea. Today, Africa and Asia are connected by the triangle of the Sinai Peninsula.
