Question

What is the different types of plate movements?Explain

Answer 1

In the theory of plate tectonics, the earth's crust is broken into plates that move around relative to each other. As a result of this movement, three types of plate boundaries are formed: divergent, convergent, and transform boundaries.

Introduction to Plate Boundaries

I hope you have never been in a car accident, but I know we all have seen one in our lives. If you have watched many movies, you almost certainly have. Have you noticed how even when the car is no longer at the accident site, you can tell what happened to it - like where it was impacted, how fast it was going (or the other car was going), and what part was hit first? Even without impacts, perhaps you can piece together what happened when a scratch shows up on the side of the car. As tectonic plates of the earth, or giant pieces of the earth's crust, move and crash into each other, similar tell-tale signs show up to give us some ideas about how they move with relation to each other.

The theory of plate tectonics states that the crust of the earth is broken up into large pieces, or plates, that move around by floating on top of the liquid layer of the earth known as the mantle. This process is driven by convection currents within the mantle. Convection currents are formed by hot magma near the core rising towards the surface, while cooler magma near the crust sinks, setting up a current that causes the plates to move. These currents are the primary driving force behind plate movement. This theory was the result of decades of work and observations made of the earth's surface. It is still the first model to neatly explain all the pieces of data scientists couldn't explain when they thought the surface of the earth was stationary.

The red lines show where the crust is divided into several plates.

The map above may seem confusing at first, but the main thing is that the colored lines show the lines where the crust is broken up into many different plates. Most are named after the continents that are contained on them.

Some plates are entirely oceanic crust, or crust under the ocean, while others are a combination of oceanic and continental crust, which is crust of the continents. The boundary where two separate plates meet is where all the action occurs and is called a fault. A fault is a crack in the earth's crust resulting from the movement of the two plates.

Getting back to the example of cars, when two cars are next to each other, there are three possible ways for the cars to move with relation to each other. Plates act in a similar manner.

3 Types of Plate Boundries

Continental Drift | 3 Types of Rocks | 3 Types of Plate Boundries

Divergent plate

Divergent:

     Almost all the Earth's new crust forms at divergent boundaries, but most are not known because they lie deep under the oceans. These are zones where two plates move away from each other, allowing magma from the mantle to rise up and make a new crust. Divergent boundaries are where the plates move apart. Seafloor spreading is a procces in which the magma creates new land under water and this process takes over millions of years to form a ten foot hill cause the growth ranges from two-ten centimeters per year. The magma is buoyant and creates more ridges and an example of this is Mid-Atlantic Ridge.  

covergent plates

Convergent:

convergent  is collision of two plates. A collision of a less dense continental plate with a more  denser oceanic plate collides with a continental plate and the ocean plate goes under the continental plate. This takes a great deal of energy and results in the melting the continental crust, vulcanism occurs. The kinds of volcanoes which can occur depends on the chemical composition of the magma which desides its viscosity and there are three different types of flow one is Basaltic is wheni t makes lava plains or sheild valcanos, Andesite is when it  makes strato-volcanoes , Dacite or rhyolite is when it makes a crater such as St. Helens.

transformal plate

Transform:

      here two plates slide by one another in opposite directions. The San Andreas Fault is the most well-known (and most deadly) translational interface. The two plates slides by one another along a large scale fault. Since these are two large pieces of rock, there is a great deal of frictional coupling that occurs. Sometimes the plates get locked in some local region and great deal of strain energy is stored in that region. Eventually, the strain energy builds up to the point where the it is suddenly released which creates a large scale earthquake.In a transverse wave the particle displacement is perpendicular to the direction of wave propagation. one-dimensional transverse plane wave propagating from left to right. The particles do not move along with the wave; they simply oscillate up and down about their individual positions as the wave passes by.
