HOW MOUNTAINS STRENGTHEN THE EARTH'S CRUST
The Earth's crust, the surface on which we daily walk and build our houses
safely, in fact moves on a layer called the mantle which is denser than the crust. If
there was not a system in place to keep this motion under control, continual shocks
and quakes would occur on the Earth and the world would be a truly unlivable
place. And yet, the mountains and their extensions under the ground greatly de-
crease underground movements, and hence such shocks.
The Earth's mountains have come about as a result of movements and clashes of
huge plates which make up the planet's crust. When two of these plates collide, one
usually slides under the other. The plate on top is pushed up and so forms moun-
tains. At the same time, the plate at the bottom proceeds under the ground and
forms a deep protrusion. This means that mountains have deep downward protru-
sions that are as large as those visible on the surface. In other words, mountains are
firmly rooted in the Earth's layer called the mantle.
Therefore, mountains effectively clench the Earth's plates by stretching above
and below the ground at the conjunctions of these plates. In this way, mountains
prevent the crust of the Earth from sliding on the magma layer or between its own
layers. In short, we may compare mountains to nails firmly holding pieces of wood
together. This characteristic of the mountains, through counteracting the unstable
nature of the Earth's crust, prevents shocks to a significant degree.
These magnificent-looking mountains also have other roles to play in maintain-
ing certain balances on the Earth, especially in dispersing heat.
The temperature difference between the equator and the Earth's poles is about
100°C (212°F). If such a difference arose on the surface level, storms at blinding
speeds reaching 1,000 km (621 miles) per hour would devastate the Earth. However
the uneven surface of the Earth blocks strong air currents that such heat differences
could cause. These mountain ranges begin with the Himalayas in China, continue
with the Taurus mountain range in southern Turkey, and then again up into the
Alps of Europe. The mountain ranges of the Atlantic and Pacific Oceans also figure

into this equation.
Like all other details on the Earth, what is manifested in the mountains is part of
Seeing these magnificent examples, what man must acknowledge is that the most
important fact of his life is his duty to serve Allah and to work for this and this
alone. Because man is in need of countless blessings, whereas Allah is Rich Beyond
