Plate Tectonics

Plate tectonics are plate movements which will in turn cause earthquakes, volcanic eruptions, mountain ranges, and islands.

Why can diamonds form in the mantle?

User Avatar

Asked by Wiki User

The weight of the rocks above the mantle results in high pressure.
Diamonds need high temperatures and pressure to form from carbon. Diamonds form in the mantle in certain zones where conditions are right for them to do so.

There just happens to be the right critical temperature-pressure-mineral environment in the mantle in certain zones for their formation.

Is mount adatara a plate boundary or a hotspot?

User Avatar

Asked by Wiki User

Mount Adatara is associated with a convergent plate boundary, as are all of Japan's volcanoes.

unequal distribution of heat within Earth.

What countries are part of the mid ocean ridge?

User Avatar

Asked by Wiki User

Since it is called the 'mid ocean ridge' , it is in the middle of the ocean, far from land/countries.

However, with one exception, Iceland. The mid Atlantic ocean ridge continues above the surface of the ocean, and has formed the island of Iceland.

Is north american plate oceanic?

User Avatar

Asked by Wiki User

NO!!! Most of it is above the ocena.

However, the eastern seaboard of the USA marks the edge of the submarine part of that plate.

If you look at a map of the eastern seaboard, without the ocean , the it fits neatly into the round should of Saharan North Africa; plate tectonics. !!!!!

What regions are most affected by earthquakes?

User Avatar

Asked by Wiki User

The regions that are located along the tectonic plate boundaries, such as the pacific ring of fire, are most prone to earthquakes due to the movement and interaction of the earth's crustal plate.

What is the theary of plates tectonics?

User Avatar

Asked by Wiki User

The theory of plate tectonics states that the Earth's lithosphere (the solid outer layer) is divided into several large plates that move relative to each other. These plates float on the semi-fluid asthenosphere underneath. Plate boundaries are where the plates interact, resulting in processes like earthquakes, volcanic activity, and the formation of mountain ranges. This theory helps explain the distribution of continents, the occurrence of earthquakes and volcanoes, and the formation of oceanic trenches and mountains.

What is the earths very top of the mantle combined?

User Avatar

Asked by Wiki User

The very top of Earth's mantle is known as the lithosphere. It is a rigid layer that consists of both the uppermost part of the mantle and the crust above it. The lithosphere is broken into tectonic plates that float on the semi-fluid asthenosphere beneath it.

One hypothesis states that plate movements results from convection currents in the?

User Avatar

Asked by Wiki User

Earth's mantle. These convection currents are driven by heat from the Earth's core, which causes material in the mantle to become less dense and rise, and denser material to sink. This movement of the mantle material pushes and drags the tectonic plates along with it.

What process allows the tectonic plates to move?

User Avatar

Asked by Wiki User

Tectonic plates move due to a process called plate tectonics. It is driven by the movement of molten rock in the Earth's mantle, which causes the plates to slowly drift and collide with each other. This movement is caused by convection currents in the mantle, creating a continuous cycle of plate motion.

Unlike what happens to the lithosphere at a duvergent or a convergent boundary the lithosphere at a transform fault boundary?

User Avatar

Asked by Wiki User

at a transform fault boundary does not experience any significant formation or destruction. Instead, it undergoes horizontal sliding past each other. This movement can result in earthquakes as the two plates grind against each other.

Are metals mined from the earth's mantle or crust?

User Avatar

Asked by Wiki User

Metals are primarily mined from the earth's crust, which is the outermost layer of the Earth. The crust contains a wide range of minerals and metal ores that can be extracted through mining processes. The earth's mantle, which lies beneath the crust, is composed mainly of solid rock and does not contain significant deposits of metals that are economically viable to mine.

What do geologists believe heats thee upper mantle portion of the asthenosphere?

User Avatar

Asked by Wiki User

Geologists believe that the upper mantle portion of the asthenosphere is primarily heated by the residual heat left over from the formation of the Earth, known as radiogenic heat. This heat is generated by the decay of radioactive isotopes present in the mantle. Other sources of heat include the heat transferred from the core and the heat produced by ongoing mantle convection.

What are structures on earth that move on the asthenosphere?

User Avatar

Asked by Wiki User

One example of a structure on Earth that moves on the asthenosphere is a tectonic plate. These plates are huge sections of Earth's lithosphere that float and move on the semi-fluid asthenosphere. The movement of these plates is responsible for phenomena such as earthquakes, volcanic activity, and the formation of mountains.

How does the theory of plate tectonics explain how mountains form?

User Avatar

Asked by Wiki User

The theory of plate tectonics explains that mountains form when two tectonic plates collide. This collision causes one plate to be forced beneath the other, creating intense pressure and causing the Earth's crust to buckle and fold, forming mountains. This process is known as convergent plate boundary.

What does the time-distance graph of seismic waves show?

User Avatar

Asked by Wiki User

The time-distance graph of seismic waves shows the relationship between the time it takes for seismic waves to travel and the distance they travel. It helps in determining the speed at which seismic waves propagate through the Earth's interior and provides information about the structure and composition of the Earth's layers.

In shiatsu the points are called?

User Avatar

Asked by Wiki User

In shiatsu, the points are called tsubos. These tsubos are specific points on the body that correspond to the meridians or energy pathways. Pressure is applied to these points to stimulate and balance the flow of energy in the body.

What was created when the Arabian and the African tectonic plates diverged?

User Avatar

Asked by Wiki User

When the Arabian and African tectonic plates diverged, the Red Sea was created. This divergence resulted in the formation of a rift or a gap between the two plates, which eventually filled with seawater to form the Red Sea.

In the plate tectonics theory the lithosphere is divided into?

User Avatar

Asked by Wiki User

It is divided into lots of different plates. Some people think that all the continents where once all one big land mass. That theory is called Pangea.

How does the temperature and density drive the convection currents in the mantle?

User Avatar

Asked by Wiki User

Temperature differences in the mantle drive convection currents because warm material is less dense and rises, while cooler material is more dense and sinks. This movement creates a circular flow as the cooler material sinks and gets heated, while the warmer material rises and cools down. The density variations caused by the temperature differences are a key driver of convection in the mantle.
