divergence of continental crust create rift zones e.g.east african rift valley.firstly,divergence will create updoming of the area.after that step faulting will take place and that will result in narrow linear sea formation like red sea.finally separation of land and ocean ridge will occur.
No, the oceanic crust is denser. That's why the land areas "float" so much higher than the ocean bedrock.
Ocean trenches and Island arcs.
All major plates contain both continental and oceanic crust except for the Pacific and Nazca plates.
Because the oldest parts reach the continental crust and then the ocean floor sinks beneath the continental crust, into the mantle.
The oceanic crust, or the crust of the earth that is under water, is between 15,840 feet and 31,680 feet thick. The continental crust, or the crust not covered in ocean water, is between 105,600 feet and 158,400 feet thick.
a rift valley
An example of continental to continental divergence is the ongoing separation of the African Plate and the Eurasian Plate along the East African Rift. This tectonic boundary is causing the African Plate to split into two separate plates, resulting in the formation of new oceanic crust and eventually a new ocean basin in millions of years.
When two continental plates collide, the crust is thickened, buckled and deformed--gaining elevation. Mountain chains are the result; their creation occurring over periods of millions of years.
Continental crust is less dense and thicker than oceanic crust, causing it to float higher on the mantle. The continental crust is also compositionally different, with a greater amount of less dense materials like granite compared to the basaltic composition of oceanic crust. This difference in density and composition results in the continental crust floating higher on the mantle.
Ocean crust is younger than landform crust. Oceanic crust is constantly being created at mid-ocean ridges through volcanic activity, making it much younger in comparison to the older landform crust found on continents.
younger
From the colliding plates called Plate Tectonics which two continental crust/ two oceanic crust/ continental - oceanic crust will collide then the one that is denser will go in the mantle that we called Subduction after that happens the one continental crust will go upward until volcano will formed that is called Upthrust Faulting. It is either the crust will form mountain or volcano but it depends upon the pressure in the mantle that makes the landform to have a Magma Chamber
mountains
When two continental plates converge, a major landform created is a mountain range. The intense pressure and collision between the plates causes the Earth's crust to uplift, forming large mountain ranges such as the Himalayas or the Alps.
Continental crust is the thicker of the two: it extends far beneath and above the Oceanic crust.
Continental crust is far older than oceanic crust.
It is not. The oceanic crust is thinner than the continental crust!
