There are several reasons - continental crust is less dense than the magma below - also - through a process known as Isostatic Equilibrium the continental crust maintains its level above the mantle.
When oceanic crust contacts continental crust at plate boundaries there is a subduction zone where the oceanic crust is pushed under the continental crust because is it much thinner and less massive.

What is the largest layer of earths surface?
The largest layer of Earth's surface is the crust, which is divided into oceanic and continental crust. The continental crust is thicker and less dense than the oceanic crust, covering about 40% of the Earth's surface.
What do you call the thin outer layer of the earth's surface?
The Crust
What is meant by continental crust and oceanic crust?
They are two different types of crust. Continental crust is heavier than Oceanic crust, so when the two collide, the Continental crust 'subducts' under the Oceanic Crust. 'Crust' referring to the tectonic plates, the surface of the Earth we stand on.
What is the name of the crust not under the ocean?
The crust not under the ocean is called continental crust. It is thicker and less dense compared to oceanic crust and forms the landmasses on Earth's surface.
What are the 2 types of crust that cover the earth's surface which one is more dense?
The Earth's surface is covered by two types of crust: continental crust and oceanic crust. Continental crust is thicker and less dense, primarily composed of lighter rocks like granite, while oceanic crust is thinner and more dense, mainly composed of heavier basaltic rocks. As a result, oceanic crust is denser than continental crust.

The largest layer of Earth's surface is the crust, which is divided into oceanic and continental crust. The continental crust is thicker and less dense than the oceanic crust, covering about 40% of the Earth's surface.
What is the name of the thin rocky layer on the surface of earth?
The crust, which is subdivided into continental crust and oceanic crust.
What are the 2 types of crust that cover the earth's surface?
The two types of crust that cover the Earth's surface are oceanic crust, which is thinner and denser, and continental crust, which is thicker and less dense. Oceanic crust is mainly composed of basalt, while continental crust is primarily composed of granite.

What is the top most layer of the earth's surface?
The topmost layer of the Earth's surface is called the crust. It is the outermost solid shell of the Earth and is composed of various types of rocks, minerals, and soil. The crust is divided into two types: continental crust, which makes up the continents, and oceanic crust, which forms the ocean floors. The thickness of the crust varies, with continental crust being thicker than oceanic crust.
What layer of the earth can you touch?
You can touch the Earth's crust, which is the outermost layer of the Earth's surface where we live. It is composed of solid rock and consists of both the continental crust and the oceanic crust.
On which layer of the earth can you find granite?
You would find granite in the continental crust.
What is the name of the crust not under the ocean?
The crust not under the ocean is called continental crust. It is thicker and less dense compared to oceanic crust and forms the landmasses on Earth's surface.

What is the continental crust of the earth?
The continental crust is the outermost layer of the Earth's surface that makes up the continents. It is thicker and less dense than the oceanic crust, primarily composed of granitic rocks such as granite and sedimentary rocks. The continental crust is divided into several tectonic plates that float on the semi-fluid asthenosphere layer beneath them.
Why does water float on Earth's surface?
Oceanic crust is denser than continental crust, it floats lower in earths mantle.
