Which rock makes continental and oceanic crust?

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.


The light colored rock that makes up most of the continental crust is what?

The light colored rock that makes up most of the continental crust is granite. It is a coarse-grained igneous rock composed mainly of quartz and feldspar minerals. Granite is less dense than the dark basaltic rock that makes up oceanic crust.

What layer is made up of solid rock?

The solid rock layer of the Earth is known as the crust, which is the outermost layer of the planet. The crust is divided into two types: continental crust, which makes up the continents, and oceanic crust, which makes up the ocean floors. The thickness of the crust can vary, with continental crust being thicker than oceanic crust.


The mineral composition of the oceanic crust is similar to the composition of what rock?

The mineral composition of the oceanic crust is similar to the composition of basalt rock. Basalt is a type of volcanic rock that contains minerals such as feldspar, pyroxene, and olivine, which are also commonly found in the oceanic crust.
