The largest tectonic plate is the Pacific plate, measuring over 100 million square kilometres. It is known as an oceanic plate as most of its crust is below sea level. At its centre, the Pacific plate has a hot spot whic... More »

Hawaii sits on the Pacific Plate. Underneath this vast tectonic plate are hot spots, locations beneath the surface of the Earth where magma accumulates. This magma occasionally rises and solidifies on Earth's surface, fo... More »

The plate tectonics theory suggests that the outer shell of the Earth's surface is split into a few plates that move along the mantle, forming a hard shell, with pressure from mid-ocean ridges and subduction zones causin... More »

The seven major lithospheric plates are the African plate, Antarctic plate, Eurasian plate, Indo-Australian plate, North American plate, South American plate and Pacific plate. These are also called Earth's tectonic plat... More »

The most common rocks on top of oceanic plates are basaltic rocks, which are denser than ones found on continents; these are found on top of the oceanic plates because they are pieces of the oceanic plates that have been... More »

Tectonic hazards are geological results of plate shifting exhibited by volcanic eruption, glacial erosion, tsunamis and earthquakes. Earthquakes are the most commonly reported hazards because of the greater likelihood of... More »

A plate boundary is a location where two tectonic plates meet. There are three different types of tectonic plate boundaries, which are defined by the relative motion of each plate. The three types of plate boundaries are... More »
