Jan 28, 2017 · The main differences are the thickness and nature of the crust in oceanic and continental plates. oceanic plates are formed at divergent boundaries mainly at mid ocean ridges. The material that is poured out are basaltic lave in nature. Basalt is denser and heavier than the granite that makes up continental plates. Oceanic plates are much thinner than the continental …

Jan 28, 2017 · The material that is poured out are basaltic lave in nature. Basalt is denser and heavier than the granite that makes up continental plates. Oceanic plates are much thinner than the continental plates. When an oceanic plate meets a continental plate at a convergent boundary the oceanic plate is forced under the continental plate and destroyed.

Subduction > An oceanic plate goes under a continental plate and causes volcanism on the continental plate. This occurs because the continental plate is less dense. An example of oceanic slab subduction would be the Andes mountains of South America, which run along the western side of that continent. Mountain ranges can form when two continental plates collide as, it is …

May 7, 2018 · Oceanic crust is largely made up of basalt, diabase, gabbro and other volcanic rocks. Continental is largely granitic. Oceanic crust is largely made up of basalt, diabase, gabbro and other volcanic rocks. Continental crust is composed largely of granitic rocks that are of low-density. You can read about continental crust and what it is composed of in this Socratic …

Aug 22, 2017 · The location of a convergent boundary stays reasonably constant. When an ocean plate converges with a continental plate. The Ocean plate is driven down creating a subduction zone. The subduction zone often creates an ocean trench at the point the two plates meet. The continental plate is pushed upward as the ocean plate is pushed under the continental plate. …

Apr 9, 2016 · Rising magma pushes against and along tectonic plates, which eventually moves the plates together, apart, or along each other. Convection currents happen in fluids with a heat source. Hot liquid or gas near the heat source becomes hotter and less dense, so moves upwards. This forces the cooler stuff at the top to move back down. As the hot molecules …

Oct 11, 2016 · The rocks of the Ocean plates get compressed under heat and pressure and turned into metamorphic rocks. The rocks of the Ocean plates that get pushed further under the continental plates get melted and turned into igneous rocks. These melted rocks form volcanos along the edges of the subduction zones, such as the Pacific ring of fire.

Jan 20, 2017 · The theory of plate tectonics explains the formation of the Himalayans by the collision of two continental plates. Most places on the earth the convergent boundaries are places with the a continental plate collides with an oceanic plate. In a convergent boundary where an oceanic plate meets a continental plate the oceanic plate is subducted or pushed under the …

Feb 21, 2018 · Continents and tectonic plates are related because continents have tectonic plates beneath them. Every continent has one or more tectonic plate underneath them. Therefore, they are related because these plates under the continents can …

Jun 5, 2017 · Plate tectonic is newer form of Continental drift with more evidence and an proposed mechanism for the movement of the Continents. Continental drift was rejected at the time it was proposed despite substantial evidence to support the theory. The rejection was based on several factors. Continental drift challenged the prevailing theories of uniform processes, …
