Answer:
- The continental crust is the layer of granitic, sedimentary and metamorphic rocks which form the continents and the areas of shallow seabed close to their shores, known as continental shelves. It is less dense than the material of the Earth's mantle and thus "floats" on top of it.
- continental crust, the outermost layer of Earth's lithosphere that makes up the planet's continents and continental shelves and is formed near subduction zones at plate boundaries between continental and oceanic tectonic plates. The continental crust forms nearly all of Earth's land surface.
- The continental crust forms one-third of the Earth's surface, and makes up all of the dry land found on Earth. The continental crust varies in thickness between 6 and 43 miles (25 and 70km). ... This is because Earth does not replace the rocks in its continental crust from the mantle as often as its does the oceanic crust.
