The Earth's crust is an extremely thin layer of rock, like the skin of an apple in relative terms. It amounts to less than half of 1 percent of the planet. But the crust is exceptionally important, and not just because we live on it.ceanic crust covers about 60 percent of the Earth's surface. Oceanic crust is thin and youngâno more than about 20 km thick and no older than about 180 million years. Everything older has been pulled underneath the continents by subduction.
Continental Crust A layer of the earth's crust that lies under the seven continents. It is about 20 to 40 miles (35 to 70 km) thick and very old. Convergent Boundary The boundary that occurs where two plates are pushing toward each other. Crust Hard and rigid, the earth's outermost and thinnest layer. It is only a few miles (5 km) thick under the oceans and averages 20 miles (30 km) thick under the continents.
