Answer:
The correct answer is letter “C”.
Compared to the size of the entire earth, the crust is very thin.
Step-by-step explanation:
The most characteristic elements that make up the earth's crust are silicon, oxygen, aluminum and magnesium. It has three layers: sedimentary, granitic and basaltic, each composed of rocks of different characteristics. Finally, it is important to mention that the earth's crust is divided into two types: the oceanic and the continental, which is where the water and the earth of the planet are concentrated respectively.
The earth's crust is the most external of the structure of the geosphere. It is comparatively thin, with a thickness that varies depending on the region. For example, at the bottom of the ocean it can be 5 km and in mountainous areas of the continents it can be 70 km. The volumes of the earth's crust have increased over time.
