The first continental crust formed during the Archean Eon. Geologists have determined that it formed from the solidification of the lighter components of magma between 3.9 and 3.8 billion years ago.
Most continental crust had formed during the Precambrian Era.

Fold mountains.
The definition of ocean continental collision means the continental crust and the ocean's crust collide with one another. A subduction is formed when the collision occurs.
They both behave as brittle solids and are both formed of a mixture of igneous, metamorphic and sedimentary rocks.
A basic mountain should be formed from the collision of continental crust and oceanic crustAnswerWhen an oceanic and a continental crust collide, the heavier oceanic crust tends to subduct under the lighter continental crust. Because of the collision and corresponding compression and also because of volcanism related to dehydration and melting of the subducted plate a mountain range is formed. The Andes mountain range is a, if not the, most typical example.
Continental /Oceanic Crust is being formed.
Fold mountains.
The mountains on the west coast of North America, such as the Cascade Range and Sierra Nevada, were mainly formed by the movement of tectonic plates. The collision of the Pacific Plate with the North American Plate caused compression and uplift, leading to the formation of the mountain ranges we see today. Additionally, volcanic activity played a significant role in shaping these mountain ranges over millions of years.

the continental crust is the plate crust formed under the continent (less density) as opposed to oceanic crustformed under the ocean(higher density)

In technical terms, the oceanic crust is denser than the continental crust so when the continental crust and the oceanic crust meet the continental crust will sink under and the oceanic crust will slide over and a volcano will be formed as well as producing earthquakes in the process.

Continental /Oceanic Crust is being formed.
The continental crust is the land. The oceanic is under the ocean.
At convergent boundaries are boundaries the crust is destroyed by subduction of oceanic crust underneath continental crust or other oceanic crust.
