What are 3 facts about the oceanic crust?
Oceanic crust differs from continental crust in several ways: it is thinner, denser, younger, and of different chemical composition. Like continental crust, however, oceanic crust is destroyed in subduction zones. The lavas are generally of two types: pillow lavas and sheet flows.
How old is the crust?
The average age of the current Earth’s continental crust has been estimated to be about 2.0 billion years. Most crustal rocks formed before 2.5 billion years ago are located in cratons.

- The crust is deepest in mountainous areas.
- The continental and oceanic crusts are bonded to the mantle, which we spoke about earlier, and this forms a layer called the lithosphere.
- Beneath the lithosphere, there is a hotter part of the mantle that is always moving.
Why is the crust so important?
The crust is a thin but important zone where dry, hot rock from the deep Earth reacts with the water and oxygen of the surface, making new kinds of minerals and rocks. It’s also where plate-tectonic activity mixes and scrambles these new rocks and injects them with chemically active fluids.
