Webcontinental 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. WebSo this is 5 to 10 kilometers. And the continental crust is about 10 to 70 kilometers thick. And obviously, they are both rigid. They are both solid rock. Now below, when you think about composition, or what the layers are made up of, the next layer below that, this is actually the biggest layer of the earth by volume, is the mantle.
