The oceanic crust composed of sima, mafic rocks and basalt. This is the top layer of the lithosphere which is found in the ocean floor.

What is composed of the continents and the oceans floor?
Earth's crust is composed of the continents and the ocean floor.
What is the name of ocean crust?
The name of the crust beneath the oceans is called "oceanic crust." It is thinner and younger than continental crust and primarily composed of basaltic rocks.
What makes the crust unique?
What makes the crust unique is that it is the rigid, rocky outer surface of the Earth, composed mostly of thinner under the oceans.
The floor of heavier rock under the oceans is composed of?
The floor of heavier rock under the oceans is primarily composed of basalt. Basalt forms from volcanic activity and makes up the majority of the oceanic crust.
What is crust classified?
Crust is classified into two main types: continental crust and oceanic crust. Continental crust is thicker, less dense, and primarily composed of granitic rocks, while oceanic crust is thinner, denser, and primarily composed of basaltic rocks. These distinctions contribute to the different geological processes and features found on land and beneath the oceans. Additionally, the crust is the outermost layer of the Earth, sitting above the mantle.
Which layer of earth is composed mostly of liquid water and different types of rock crystals such as quartz?
The layer of Earth that is composed mostly of liquid water and various types of rock crystals such as quartz is the crust. The crust is the outermost layer of Earth and is divided into the continental crust (land) and the oceanic crust (under the oceans). It is where we find a diverse range of minerals and rock formations.
What is the crust beneath the oceans?
Oceanic Crust
What is the upper layer of the Earth including the crust?
The layer of the Earth which forms the tectonic plates is composed of the crust and uppermost mantle and is called the lithosphere.
Which of these is composed of lakes rivers and oceans?
the outer space is what is composed of lakes rivers and oceans WRONG. The Hydrosphere is composed of lakes, rivers, and oceans.
What is the description of crust?
the thinnest layer of the earth
What layer of the earth can you find continents and oceans?
Continents and oceans are found on Earth's crust, which is the outermost layer of the Earth. The continents are made up of thicker continental crust, while the oceans are located on thinner oceanic crust.
The crust of the sea floor is essentially composed of?
Oceanic crust is primarily composed of the rock basalt.
