Earth Science-Exam 1 Questions and Answers 100% Pass What are the two main types of Earth's crust? Oceanic and Continental Explanation: The Earth's crust is divided into two main types: the oceanic crust, which forms the ocean floors, and the continental crust, which forms the continents. Which type of crust has higher density? Oceanic Explanation: Oceanic crust is denser than continental crust due to its composition of basaltic rocks. Which type of crust is thicker? ...
