Classification of Fault 0

Classification of Fault

Classification of Fault may be achieved on the basis of their geometry or their genesis. The geometric classification is easier, but , a genetic classification is more satisfactory. As the genetic classification is difficult...

Periodicity Of Eruption

Volcanoes are divided into three types on the basis of periodicity of eruption and interval period between two eruptions of volcano. Such as Active, Dormant and Extinct. Active Volcanoes: This are which constantly ejects lava,...

Fissure Type Of Eruption 0

Fissure Type Of Eruption

Fissure type of eruption occurs along faults and fractures. There is a slow up-welling of magma and the resultant lava spread over the ground surface. Here, it must be mentioned that the fractures are...

Intraplate Volcanism 0

Intraplate Volcanism

Volcanism in central parts of plates beyond constructive and destructive margins is not so common,  but is the surface expression of local thermal variation or hot spots in the mantle. Intraplate volcanism occurs both...

Plate Margin Volcanism 0

Plate Margin Volcanism

There are two plate boundaries where volcanic activity takes place. Constructive Margin or Divergent Plate Boundary:     The asthenosphere, over which the lithosphere is floating, is mode of peridotite. A slight degree of melting...
