i genous rock
It is made of Basalt.
basalt
The oceanic crust is primarily made of solid rock, primarily basalt. However, beneath the oceanic crust, there is a layer of partially molten rock called the mantle that flows slowly over time.
it is a mixture of volcanic rock or "cooled lava" and sedative rock
The oceanic crust is mostly made up of basalt, which is a dense volcanic rock that forms from the cooling of lava at the Earth's surface.
The rock that makes up both continental and oceanic crust is called basalt. Basalt is a mafic extrusive igneous rock that forms when lava cools and solidifies rapidly at the Earth's surface. It is commonly found in oceanic crust, while continental crust is made up of a variety of rocks including basalt.
Oceanic crust.
Oceanic plates are primarily made of basalt, which is a type of volcanic rock that forms from the cooling and solidification of magma on the ocean floor. Basalt is dark in color and has a fine-grained texture.
Oceanic plates are primarily made of basalt, which is a dark-colored, fine-grained volcanic rock that forms from the rapid cooling of lava at or near the Earth's surface.
Oceanic crust is predominately made of basaltic rock with a thin layer of sedimentary rock on top. Continental crust is predominately made of granitic rock, with a thin layer of sedimentary rock covering much of the visible surface.
AnswerThe continental plates are made up of largely granitic rock, while the oceanic plates are largely basaltic rock. Certainly some other types of rock are included, but these are the largest contributors to the material or composition. A link is provided below for more information.
