Earthquake region

The greatest concentration of earthquakes is found around the Pacific Ocean. Another stretches from the Mediterranean sea to the Hilmalayas. Both areas are the plates moving towards each other. The volcanic belt coincide with the major earthquake zone. THE PLATES AND THE RING OF FIRE REGION Advertisements

AN EARTHQUAKE

WHAT IS AN EARTHQUAKE? The vibration or tremors in the earth’s crust , caused by a sudden release of energy when the rock displaced along a fault. THE FORMATION OF AN EARTHQUAKE When two plates move towards or away from each other or slide movement is not smooth cause the friction between the moving plates […]

PLATE MOVEMENT- TRANSFORM

Slide past each other ( Transform plate) When the two plates past  slide each others. This will change the location of the original plate. Earthquakes commonly take place along the plate boundary. The Pacific plate and the North American slide past each other.

PLATE MOVEMENT- DIVERGENT

Move away from each other (DIVERGENT PLATE) When the two plates move away from each others.  As the plate moves apart, the rocks break and form fractures in the crust when an earthquake occur along the plate boundary. Magma from the mantle rises to the ocean floor through these fractures and solidifies at the plate […]

PLATE MOVEMENT- CONVERGENT

MOVE TOWARDS EACH OTHER    (CONVERGENT PLATE) When the two plates move towards or collide each others. This will make the subduction where one plate ( oceanic crust) move downwards beneath the other plate into underlying mantle and form block of mountain ( Continental crust) and oceanic ridges ( Oceanic crust). Subduction is the process which […]

THE PLATE TECTONIC MOVEMENT

How the plate moves? The convection current in the mantle inside the earth is very hot. The heat cause the magma in the mantle to expand and rise. The magma cause risen and spread out beneath the plates. As the result of this the plate moves. The repeated heating and rising of the magma set […]

PLATES

What is a PLATE? Plate is a crust together with the upper part of mantle is divided into pieces. Plate is like a jig-saw puzzle frame to the earth’s crust. There are many major plates and several smaller ones can be found.  The earth is made up of moving plate is put forward in the […]
