semi-solid rock known as the mantle. This contains more iron, magne-
sium and calcium than the crust, and is also hotter and denser, because
temperature and density in the Earth increase with depth.
At the centre of the Earth is the core, approximately twice as dense
as the mantle. The reason for that density is that it contains a higher
proportion of metals (iron-nickel alloy) than rock. The Earth's core
consists of two parts. One is the 2,200 km (1,370 miles) thick liq-
uid outer core, the other a 1,250 km (777 miles) thick solid
inner core. The liquid outer core provides the Earth's
magnetic field as the planet rotates.
The truth of this similarity between the
sky and the layers of the Earth, only identi-
fied by 20th century technology, is
without doubt another of the
Qur'an's scientific miracles.
