The outermost solid layer of the Earth, mostly consisting of crystalline rock and extending no more than a few miles from the surface to the Mohorovicic discontinuity. 3, record 1, English, - Earth%27s%20crust

Earth's outermost, rigid, rocky layer is called the crust. It is composed of low-density, easily melted rocks; the continental crust is predominantly granitic rock, while composition of the oceanic crust corresponds mainly to that of basalt and gabbro. Analyses of seismic waves, generated by earthquakes within Earth's interior, show that the crust extends about 50 km (30 miles) beneath the continents but only 5-10 km (3-6) miles beneath the ocean floors. 4, record 1, English, - Earth%27s%20crust

In composition, the Earth is made of three nested spheres. At the center of the Earth, a body of intensely hot iron and nickel forms the core. A less dense and much larger middle sphere is made of materials rich in iron, magnesium and calcium comprises the mantle. The outermost layer is a thin veneer of lighter rocks called the crust. 5, record 1, English, - Earth%27s%20crust
