Newly published research has revealed that compositional rock anomalies within oceanic plates caused by ancient tectonics influence the trajectory and speed of the plates as they plunge deep into ...

Whatever drives the movement, plate tectonic activity takes place at four types of boundaries: divergent boundaries, where new crust is formed; convergent boundaries, where crust is consumed ...

Geographic (A) and tectonic (B) maps of the Philippine Sea Plate region. Present-day plate boundaries are red (modified from ...

The Earth is made of different layers: the core, mantle and crust. Plate tectonic theory shows that the crust of the Earth is split into plates (pieces of the Earth’s crust). The movement of ...

Four types of plate tectonic activity are demonstrated in this feature. Keep an eye on the map to see where in the world the activity takes place. Also known as spreading boundary, a divergent ...

The plate belonged to a region where two major tectonic realms—the Tethyan and Panthalassa—once interacted, creating a ...

Topics include a wide range of geological concepts including plate tectonic setting of Mexico, living with volcanoes: the Mexican volcanic belt, the Mexico City earthquake, issues of water supply, ...

The country’s susceptibility to earthquakes is a consequence of its complex geological setting ... and Eurasian tectonic plates. The northward movement of the Indian Plate against the Eurasian ...
