Continental Crust
overall review score: 4.5
⭐⭐⭐⭐⭐
score is between 0 and 5
The continental crust is the thick, solid outer layer of the Earth's lithosphere that forms the continents. It is primarily composed of granitic and tonalitic rocks, making it less dense than the oceanic crust. The continental crust plays a crucial role in Earth's geology, accommodating various landforms, supporting ecosystems, and serving as the foundation for human civilization.
