Even more dramatically, the shuffling of tectonic plates can give Earth’s surface a complete makeover. More than 200 million years ago, Earth had only one huge landmass: Pangaea. Over time, the shifting of tectonic plates broke that landmass apart and...
Some of the minor plates include theArabian, Caribbean, Nazca, and Scotia plates.Over millions of years the plates have been moving relative to oneanother. The plates are moving at a few centimeters per year.When these plates bump into each other, earthquakes (地震)and volcanoes (火山) can ...
Earth’s tectonic plate boundaries are unusual because they can consist ofcontinent and ocean crust. Here are the 7 major tectonic plates of the world in a bit more detail. 1. Pacific Plate The Pacific major plate is the largest which underlies the Pacific Ocean. Specifically, it stretches al...

The Earth's crust, or lithosphere, is divided into seven major areas called tectonic plates. Each plate drifts around slowly based on convection currents in the mantle. Even though the movement is slow, tectonic plates can have enormous impacts, creating impact phenomena, like mountain ranges, ...
Convergent boundariesoccur where two plates slide towards each other to form either a subduction zone (if one plate, normally an oceanic plate moves underneath the other) or a continental collision. Subduction zones include the boundaries of the Pacific plate (e.g. Western South America) where th...
Earth’s lithosphere is composed of seven major tectonic plates, and additional minor plates. Each plate shifts somewhere between 0 and 10 mm annually. The boundaries where plates meet are sites of transformation. Depending on the type of boundary, the interactions of tectonic plates can cause ear...
Tectonic processes include, divergence, which is when plates move away from each other, convergence, when plates move toward each other and collide, Subduction zones, which occur where an oceanic plate meets a continental plate and is pushed underneath, Obduction, which occurs when the continental ...
At convergent boundaries, the plates move towards each other, causing one plate to be forced beneath the other in a process called subduction. This collision can result in the formation of mountain ranges, volcanic activity, and earthquakes. Examples of convergent boundaries include the Himalayas, ...
