The African Rift Valley is on example of this process, and eventually, this part will be separated from Africa. Another example is Iceland, which is actively volcanic because of the arrival of primary magma on the surface, as the two plates spread apart.

What event caused the changes described in the above passage?

The Meiji restoration resulted in the Japanese emperor gaining substantial power.


Where and how an eatherquake occurs?

It result from the moving of rock deep under the ground. This movement is caused by the rubbing of one plate into another. The plates have jagged edges, and so when they rub against each other, they get stuck. Since plates constantly move, the plates that are stuck create great tension, and when they are finally free, a huge amount of energy is released. Shock waves move from focus in all directions, and it causes the earth to vibrate.


What is a basal drag?

It is a force that could be contributing or complementing mantle convectional currents in the movements of lithospheric or tectonic plates. This force is generated when there is friction between convectional currents and the lithospheric or tectonic plate that lies above.


Describe the method by which energy is transferred from earth's surface to the air above it?

Its because of convection. Which is caused by a solid liquid or gas as the temperature changes. Love: H.C.S:)


How do scientists identify tectonical active regions?

Scientists use sonar images to watch how the tectonic plates move and spread to create faults or collide to create mountains and volcanoes. The tectonic plates are large pieces of the crust floating on the mantle that push and pull against each other. The more these plates move the more landforms are created, whether underneath or above water. Using the images they see how often the plates move to create these land features and use this to see how active they are. I'm sorry if any of this information ended up being wrong/too vague, I couldn't find literally anything on it for some reason and it was better than "find it yourself" :)

How are earthquacks caused?

Earthquakes are caused when the Earth's tectonic plates:Crash up against each otherGo above one anotherGo below one anotherThis is when two plates do the above. The plates are next to each other to cause this.


Where are volcanoes mostly caused?

You can find volcanoes on plate boundaries because when the plates crash into each other they cause an eruption sending all above it upwards, e.g. sending the lava upwards and the rocks causing a volcano, the tectonic plates are also the reason that things such as tsunami's occur.


When a hotspot rises and cracks the surface is it a convergent divergent or transform boundary?

When a hotspot rises and cracks the surface, it is typically associated with a divergent boundary. At divergent boundaries, tectonic plates move apart, allowing magma from the mantle to rise up and create new crust.


What is the 3 types of tectonic plate motion?

a) Divergent Plate Boundaries: Divergent plate boundaries are locations where plates are moving away from one another. This occurs above rising convection currents. b) Convergent Plate Boundaries: Convergent plate boundaries are locations where lithospheric plates are moving towards one another. The plate collisions that occur in these areas can produce earthquakes, volcanic activity and crustal deformation. c) Transform Boundary: Transform Plate Boundaries are locations where two plates slide past one another. The fracture zone that forms a transform plate boundary is known as a transform fault. Most transform faults are found in the ocean basin and connect offsets in the mid-ocean ridges.


What natural process is causing the motion of earth plates?

the mantle is pressuring the plates above which cause the boundaries we learned about to begin. The boundaries are: Convergent, Divergent, and Transform. the plates will have moved because of the boundaries either one of those three. This all will cause earthquakes and other things that i will learn about through the years of my education.


Why do plates separates from each other?

From the creation of crust by magma at divergent plate boundaries. It has been proposed that when the above crust is created, it creates in the form of an upward pointing wedge of basalt and this wedge forces the plates apart. For a more extensive discussion of this proposal see http://members.tripod.com/~charles_W/ridge.html


What plate boundary are volcanoes formed at?

Volcanoes can form at three places-1. Divergent boundaries2. Convergent boundaries (oceanic-oceanic and oceanic-continental)2. Above hot spots


Can it rain during an earthquake?

No, rain is not caused by earthquakes. Rain occurs due to moisture in the atmosphere condensing and falling to the ground as precipitation. Earthquakes are caused by the movement of tectonic plates beneath the Earth's surface.


How do divergent boundaries of oceanic crust form islands?

Divergent boundaries of oceanic crust form islands through a process called seafloor spreading. As the oceanic plates move apart, magma rises up to fill the gap, solidifies, and eventually forms new crust. Over time, this continuous process can lead to the formation of underwater volcanoes which eventually rise above sea level, forming islands.


Is an earthquake created by tectonic plates?

An earthquake IS caused by the movement of the plates under the ocean. And there is one active site which is known as "The Ring of Fire". +++ The "Ring of Fire" is a whole set of active sites right round the Pacific Ocean, above the subductions of the sea-floor plates below the surrounding continents.


In the mantle and core make tectonic plates move?

Convection currents in the mantle transfer heat, causing the tectonic plates above to move. The movement of these plates is a result of the mantle's heat-driven circulation, which leads to the shifting of crustal plates on Earth's surface. The convection currents help drive plate tectonics by pushing or pulling the plates in different directions.
