The crust that forms the continents is which?

• A. Continental crust
• B. Oceanic crust
• C. Mantle
• D. Outer core

Answer: (A)

Continental crust is the crust that forms the continents. It is thicker and less dense than oceanic crust, made mainly of granitic rocks rich in silica and aluminum. Because it’s lighter, it sits higher on the mantle and builds the landmasses we stand on. Oceanic crust, in contrast, is thinner and more dense, composed primarily of basalt, and forms the ocean floors. The mantle lies beneath the crust, while the outer core is far below and not part of the crust.
