The Earth's crust includes ocean floors and?
The Earth's crust includes oceanic and continental categories, the oceanic crust composed of basalt rock and recycled in roughly 150 million year intervals by lithospheric plate movements, and the older less dense continental crust, composed of granitic rock.
What is the compition for the crust?
Crust is made up of mainly granite, a felsic rock wit a lower density than basalt, what makes up the ocean's crust, thus why the continental crust rises up compared to ocean crust.
What are the two types of crust and which rocks make up each crust?
there are two types of crust such as the oceanic crust and the continental crust, the oceanic crust is thinner and more dense than the continental crust and is constantly being recycled via subduction upon collisions with Continental crust, and creating at mid-ocean ridges. x
What makes up the continents and the ocean floor?
Continents are made up of lighter, less dense rock types such as granite and sedimentary rocks, which are usually thicker and less dense than oceanic crust. The ocean floor, on the other hand, is composed mostly of basaltic rock that is denser and thinner than continental crust. Additionally, the ocean floor includes features such as seamounts, ridges, trenches, and abyssal plains formed by various geological processes like seafloor spreading and subduction.
What rock type is most abundant in the crust of the ocean floors?
The most abundant rock type in the ocean floor crust is basalt. This volcanic rock forms from the rapid cooling of lava at mid-ocean ridges and is a key component of oceanic crust. Basalt is typically dense and rich in iron and magnesium, distinguishing it from the continental crust, which is primarily composed of lighter granitic rocks.
What are the primary rock types that make up ocean and continental crust?
Basalts and granites.
Differences of the continental crust and oceanic crust?
The continental crust is thicker, less dense, and older than the oceanic crust. It is composed mainly of granite rocks and is found beneath continental landmasses. In contrast, the oceanic crust is thinner, denser, and younger, with basalt rocks being the dominant rock type. It forms the ocean floor and is continually created and destroyed through the process of seafloor spreading and subduction.
What is the crust beneath the ocean called?
The crust beneath the ocean is called oceanic crust. It is thinner and younger than continental crust, primarily composed of basaltic rock formed at mid-ocean ridges through volcanic activity.
The Earth's crust includes ocean floors and?
The Earth's crust includes oceanic and continental categories, the oceanic crust composed of basalt rock and recycled in roughly 150 million year intervals by lithospheric plate movements, and the older less dense continental crust, composed of granitic rock.
How do oceanic and continental crust differ?
Oceanic crust is typically thinner, denser, and younger than continental crust. It is primarily composed of basaltic rocks and forms the ocean floor, while continental crust is thicker, less dense, and contains a wider variety of rock types, including granitic rocks. Continental crust forms the continents and is older than oceanic crust.
Crust under the ocean is called?
Crust under the oceans is called oceanic crust.
What is the compition for the crust?
Crust is made up of mainly granite, a felsic rock wit a lower density than basalt, what makes up the ocean's crust, thus why the continental crust rises up compared to ocean crust.

Compared to earths continental crust earths oceanic crust is?
Earth's oceanic crust is thinner, denser, and younger than Earth's continental crust. It is primarily composed of basaltic rock, whereas continental crust is made up of less dense granitic rock. Oceanic crust is constantly being formed at mid-ocean ridges and destroyed at subduction zones.
Why is the oldest rock at the bottom of the ocean?
The oldest rock is found in the continental crust. The youngest rock is found in the oceanic crust. This is because the ocean floor is recycled every 160 million years or so in the process of plate tectonics.
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.
What is the composition of ocean crust?
It is mostly composed of basalt, and few other mineral types. It is made mostly of igneous rock, same with continental crust.
