How are the continental plants formed and how are they eventually destroyed ? (AS 1)
When two continental plates diverge, a rift valley is formed as the Earth's crust splits apart. Magma rises to the surface and creates new crust, eventually leading to the formation of a mid-ocean ridge.
rift valley Answer 2 Continents are formed when continental plates pull apart.
Subduction zones are formed when oceanic plates slide beneath continental plates. The process leads to the oceanic plate being forced into the Earth's mantle. This can result in the formation of deep oceanic trenches and volcanic activity at the surface.
When two continental plates diverge, a rift valley forms due to the pulling apart of the Earth's crust. Magma rises to fill the gap created by the separating plates, eventually leading to the formation of new oceanic crust. Over time, this process can result in the formation of a new ocean basin.
Mountain ranges are formed when plates with continental crust collide. The immense pressure causes the crust to buckle, fold, and uplift, creating mountainous terrain such as the Himalayas or the Alps.

Deep-ocean trenches are formed where seafloor tectonic plates subduct under continental plates.

New continental crust is formed at divergent plate boundaries, where tectonic plates move away from each other. As the plates separate, magma from the mantle rises and solidifies to form new crust. This process is known as seafloor spreading and creates new oceanic crust, which can eventually be uplifted and become part of a continent.
Some examples of mountain ranges created by continental-continental convergence are the Himalayas (resulting from the collision of the Indian and Eurasian plates) and the Alps (formed by the collision of African and Eurasian plates).
When it is two continental plates, new oceanic crust is formed, and when this continues, more oceanic crust is formed between the plates.

They were formed on the edges of two ancient continental plates that collided with each other in the geological past.
Oceanic crust is constantly being recycled. New oceanic crust is formed at mid ocean ridges while old ocean crust is destroyed at subduction zones. As a result there is little oceanic crust that is older than 200 million years. Continental crust does not get destroyed by subduction, so much of it has been around since the Precambrian time.
