Depending on the type of plates that collide, they either lift or subduct. When an oceanic plate collides with a continental plate, it typically slides underneath it. If two like plates collide, they crush together at the collision point and lift up broken material from both plates.
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 divergent, convergent, and transform. These plate boundaries can occur both wit
Continental and oceanic are the two types of tectonic plates. Continental plates tend to be larger than oceanic and bear the majority of a continent's mass. Continental plates tend to be much thicker on average, but less dense.
According to the U.S. Geological Survey website, tectonic plates are massive, irregular-shaped slabs of solid rock, composed of oceanic and continental lithosphere. The continental crust is made up of lightweight minerals like feldspar and quartz, while the oceanic crust is made of heavier and dense
There are seven major tectonic plates on the planet that are further subdivided into dozens of smaller plates. Geologists do not always agree on how to subdivide the minor plates. Each plate is in motion relative to the other plates.
Plate tectonics is primarily caused by Earth's cooling mechanism, which generates convection currents in the planet's mantle that trigger slow but constant tectonic plate movement. This phenomena occurs on the boundaries of adjacent plates, which are classified as divergent, convergent and transform
Each continent is embedded onto plates, which are made from lithospheres - Earth's outermost layer. Because this layer is stronger than the underlying layer, it is able to move. Several forces encourage it to do this, which means Earth's landmass remains the same, but the location of continents shif
According to About.com, plate tectonics is the scientific theory that attempts to explain the movement of the Earth's lithosphere, which has formed the landscape features seen across the globe. It provides geology with a comprehensive theory that explains how the Earth works.
Tectonic plates shift as a result of the intense heat at the Earth's core, which causes molten rock in the mantle layer to rise, while cooler rock near the surface sinks back down. This is a process referred to as thermal convection.
Earth's tectonic plates move due to the movement of magma in the mantle underneath the crust. Extreme temperatures inside the planet's core cause a convection cycle in which hot magma rises to the surface and eventually sinks back toward the core as it cools.
