Which is thicker continental crust or oceanic?

Continental crust is also less dense than oceanic crust, though it is considerably thicker; mostly 35 to 40 km versus the average oceanic thickness of around 7-10 km. About 40% of the Earth’s surface is now underlain by continental crust.Click to see full answer. Similarly, it is asked, why continental crust is thicker than oceanic crust?The continental crust is denser than the oceanic crust, because it contains more hard rock like igneous and metamorphic. These form the bedrock of the continents, otherwise the continental plates are less stable. These formations extend much deeper into the Earth’s interior relative the continental and oceanic plates.Secondly, which type of crust is thicker? At 25 to 70 km, continental crust is considerably thicker than oceanic crust, which has an average thickness of around 7–10 km. About 40% of Earth’s surface area and about 70% of the volume of the Earth’s crust is continental crust. Most continental crust is dry land above sea level. Also Know, is continental crust thicker than oceanic? Continental crust is thicker, 22 miles (35 km) on average and less dense than oceanic crust, which accounts for its mean surface elevation of about 3 miles (4.8 km) above that of the ocean floor (Archimedes’ principle). Continental crust is more complex than oceanic crust…How thick is the oceanic crust?The oceanic crust is 5 km (3 mi) to 10 km (6 mi) thick and is composed primarily of basalt, diabase, and gabbro. The continental crust is typically from 30 km (20 mi) to 50 km (30 mi) thick, and it is mostly composed of less dense rocks than is the oceanic crust.
