Apr 5, 2018 · The oceanic crust is mainly composed of basalt and gabbro, both igneous rocks. Basalt forms from lava that cools rapidly at mid-ocean ridges, while gabbro is created from …

Sep 23, 2023 · When oceanic and continental crusts converge at a plate boundary, the denser oceanic crust is typically forced beneath the less dense continental crust, a process known as …

Mar 26, 2018 · B. Both oceanic and continental crust are made of granite. This statement is also false. The continental crust is primarily composed of granite, which is a light-colored, less …

Oct 13, 2016 · The temperature of the oceanic crust varies significantly with depth. Generally, the oceanic crust is made up of basalt and can be found at depths ranging from about 5 to 12 …

Mar 24, 2018 · Continental crust and oceanic crust differ mainly in composition, thickness, density, and age. Continental crust is thicker, less dense, and older, composed mainly of …

Mar 3, 2020 · When oceanic crust collides with continental crust, the oceanic crust is subducted beneath the continental crust due to its higher density. This process leads to the formation of …
