What is formed in trench trench boundary?

Trenches are formed by subduction a geophysical process in which two or more of Earth’s tectonic plates converge and the older denser plate is pushed beneath the lighter plate and deep into the mantle causing the seafloor and outermost crust (the lithosphere) to bend and form a steep V-shaped depression.

What type of plate boundaries are found in the Atlantic Ocean?

The Mid-Atlantic Ridge is a mid-ocean ridge (a divergent or constructive plate boundary) located along the floor of the Atlantic Ocean and part of the longest mountain range in the world.

What type of plate boundary occurs between Eurasian plate and North American plate?

Divergent boundary. When two plates are moving apart a divergent boundary takes place. The North American plate and the Eurasian plate share a boundary in the middle of the Atlantic ocean. Here they move apart from each other at this boundary and the mantle from below rises to the surface to a create a new crust.

Which two tectonic plates are separated by a mid-ocean ridge?

Seafloor spreading occurs along mid-ocean ridges—large mountain ranges rising from the ocean floor. The Mid-Atlantic Ridge for instance separates the North American plate from the Eurasian plate and the South American plate from the African plate.

Which type of seismic waves do the most damage in an earthquake?

Rayleigh waves cause both vertical and horizontal ground motion. These can be the most destructive waves as they roll along lifting and dropping the ground as they pass.

Where is the epicenter of a vertical fault?

However unlike your fingers the whole fault plane does not slip at once. The rupture begins at a point on the fault plane called the hypocenter a point usually deep down on the fault. The epicenter is the point on the surface directly above the hypocenter.

Where is the Hayward fault line?

San Francisco Bay
The Hayward Fault Zone is a geologic fault zone capable of generating destructive earthquakes. This fault is about 74 mi (119 km) long situated mainly along the western base of the hills on the east side of San Francisco Bay.

What type of plates formed the Mariana Trench?

The Mariana Trench in the South Pacific Ocean is formed as the mighty Pacific plate subducts beneath the smaller less-dense Philippine plate.

Where is the Marianas Trench?

the Pacific Ocean
The Mariana Trench in the Pacific Ocean is so deep your bones would literally dissolve. What’s down there in its black crushing depths? Somewhere between Hawaii and the Philippines near the small island of Guam far below the surface of the water sits the Mariana Trench the deepest spot in the ocean.May 29 2020

What geologic processes formed the Marianas Trench?

The Mariana Trench was formed through a process called subduction. Earth’s crust is made up of comparably thin plates that “float” on the molten rock of the planet’s mantle. While floating on the mantle the edges of these plates slowly bump into each other and sometimes even collide head-on.

What is Ocean-Ocean convergent boundary?

At an ocean-ocean convergent boundary one of the plates (oceanic crust and lithospheric mantle) is pushed or subducted under the other (Figure 4.6. 1). … It mixes with the overlying mantle and the addition of water to the hot mantle lowers the crust’s melting point and leads to the formation of magma (flux melting).

What is a convergent plate boundary also called?

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 and volcanoes. As the plates collide the oceanic plate is forced beneath the continental plate.

What are the three types of convergent boundary?

Convergent boundaries where two plates are moving toward each other are of three types depending on the type of crust present on either side of the boundary — oceanic or continental . The types are ocean-ocean ocean-continent and continent-continent.

What type of plate movement is vertically across the Atlantic ocean?

The most significant vertical movements of the oceanic crust in the Central Atlantic are characteristic of transverse ridges confined to transform fracture zones. These movements are also recorded in some local depressions of the Mid-Atlantic Ridge (MAR) and in older structures of deep-sea basins.

What type of plate boundary makes up the Mid-Atlantic Ridge?

divergent boundary

A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface solidifying to create new oceanic crust. The Mid-Atlantic Ridge is an example of divergent plate boundaries.

What type of boundary is the Mid-Atlantic Ridge?

divergent boundaries
Perhaps the best known of the divergent boundaries is the Mid-Atlantic Ridge. This submerged mountain range which extends from the Arctic Ocean to beyond the southern tip of Africa is but one segment of the global mid-ocean ridge system that encircles the Earth.Sep 15 2014

What type of plate boundary is between the Philippine plate and Eurasian Plate?

3 show that the segments of the Philippine-Eurasia plate boundaries are different with each other though they are all convergent boundaries. The interaction between the plates could be discussed one by one in four parts: the Nankai trough the Ryukyu trench the Tanwan area and the Philippine islands.

What type of plate boundary is found between the Australian and Eurasian plates?

This plate boundary is called the Sumatran Subduction Trench and it is where the oceanic Indian/Australian plate is slowly descending beneath (subducting under) the continental Eurasian plate at a rate of about 4.5 cm/year (2 inches/year).

What plate boundary is formed between African Plate and Eurasian Plate?

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 type of plate boundary is the Aleutian Trench?

convergent plate boundary
The Aleutian Trench (or Aleutian Trough) is an oceanic trench along a convergent plate boundary which runs along the southern coastline of Alaska and the Aleutian islands.

What observation is the Mid-Atlantic Ridge?

Q. Which observation about the Mid-Atlantic Ridge region provides the best evidence that the seafloor has been spreading for millions of years? The bedrock of the ridge and nearby seafloor is igneous rock. The ridge is the location of irregular volcanic eruptions.

At which type of boundary does ridge push occur?

divergent boundary

The ridge-push force is created by tectonic plates moving away from a divergent boundary due to their higher elevation than the surrounding ocean floor. These forces are influenced by the high rates of volcanism occurring beneath mid-ocean ridges.

What type of plate boundary is capable of producing the largest earthquakes?

At convergent plate boundaries where two continental plates collide earthquakes are deep and also very powerful. In general the deepest and the most powerful earthquakes occur at plate collision (or subduction) zones at convergent plate boundaries.

Which waves are responsible for the earthquake?

The two main types of waves are body waves and surface waves. Body waves can travel through the Earth’s inner layers but surface waves can only move along the surface of the planet like ripples on water. Earthquakes send out seismic energy as both body and surface waves.

Which type of earthquake waves do the most damage quizlet?

Surface waves make the rock particles travel in a circle/elliptical motion. Of all the three waves surface waves cause the most damage.
