Consider the statements regarding different types of plates in ‘Plate Tectonic Theory’.
1) Destructive plate boundary is one in which continuous upwelling of molten material ie lava takes place.
2) Divergent plate boundary is one which two plates slide past one another thus neither creating nor destroying continental landmass.
3) Convergent plate boundary is one in which one plate overrides the other plate.
Choose the correct statement/s from the following code.
1, 2 only.
2 only.
3 only.
All the above.
Explanation:
Divergent plate boundary or constructive plate boundary:A tectonic boundary where two plates are moving away from each other and new crust isforming from magma that rises to the Earths surface between the two plates. The middle ofthe Red Sea and the mid-ocean ridge (running the length of the Atlantic Ocean) aredivergent plate boundaries.Convergent plate boundary or destructive plate boundary:It is a tectonic boundary where two plates move towards each other. If thetwo plates are ofequal density, they usually push up against each other,forming a mountain chain. If they areof unequal density, one plate usually sinks beneath the other in a subduction zone.The western coast of SouthAmerica and the Himalayan Mountains are convergent plate boundaries. Also called active margin , collision zone.Transform plate boundary:Transform plate boundary is one in which two plates slide past one another thus neithercreating nor destroying continental landmass.
