There are two main types of tectonic plates:oceanic and continental. Oceanic - Oceanic plates consist of an oceanic crust called "sima". Sima is made up primarily of silicon and magnesium (which is where it gets its name). Continental - Continental plates consist of a continental crust called...
Earthquake & tectonic plates. Earth structure and plate boundaries categories: Transform boundaries, Convergent boundaries (Subduction boundaries, Collisional boundaries)
aone interesting property of the continental and oceanic crust is that these tectonic plates have the ability to rise and sink 大陆和海洋外壳的一有趣的物产是这些地壳构造板块有能力上升和下沉[translate]
I. Tectonic Plates: Definition and Composition 1.1 Definition: Tectonic plates are large sections of the Earth's lithosphere that float on the semi-fluid asthenosphere beneath. 1.2 Composition: These plates are composed of both continental and oceanic crusts, along with the underlying uppermost mantle...
Oceanic platesare relatively thin (about 6-10 km) and contain very heavy (dense) rocks such as basalt. Continental platesare considerably thicker (35-40 km) but contain lighter (less dense) rocks such as granite. The plates fit together like pieces of a large jigsaw. Tectonic plates meet ...
Surrounding the core lies the mantle, and above the mantle at the surface is the crust of the Earth. There are two kinds of crust, denser, basaltic, oceanic crust which is found under oceans, and continental crust which is less dense and mostly composed of granite. Another important layer ...

Characteristics: Contains both oceanic crust (mostly basaltic) and a small section of continental crust. Interactions: It interacts with many other plates, leading to the formation of the “Ring of Fire,” a zone known for earthquakes and volcanic activity around the Pacific Ocean. ...
Collision zones form whentwo continental plates collide. Neither plate is forced under the other, and so both are forced up and form fold mountains. Which plate will Subduct after the collision of oceanic and continental crusts explain why?
The Indo-Australia plate is a major plate combining the Australian and Indian Plates. But they are widely considered to be two separate plates. TheIndo-Australia platestretches from Australia to India. It also includes the oceanic crust of the Indian Ocean. The northeast side of the Australian ...
