• From the last lesson we know that the Earth’s crust is a thin fragile layer, made up of

• Oceanic crust is:

– Mostly dense basalt

– 5-10 km thick

– “Young” No more than 200 million years old

• Continental crust is

– mostly less dense granite

– Up to 50 km thick

– Very old-rocks up to 3.5 billion years
