The oceans are said to be the source of life. The
enormous, blue, calm oceans are the signatures of
the planet earth. They cover nearly three-fourths
of the surface of the earth. This is equal to 71
percent of the earths entire surface or about 361
million sq km (140 million sq mi). Its average
depth is 5000 m (16, 000 ft), and its total volume
is about 1, 347, 000, 000 cu km (322, 300, 000 cu
mi). This includes the Atlantic, Pacific, and
Indian oceans. These oceans are bordered by the
continent...

ter> Describe the frequency, origin and
distribution of earthquakes at mid-ocean ridges,
ocean basins, subduction zones and continental
shields. Earthquakes are happening
almost everyday all over the world. Most of the
time earthquakes are not strong enough to be felt
by people, but the shaking caused by an earthquake
is recorded by a seismogram. These are located all

The core is divided into two parts, the solid
inner core and the liquid outer core. The inner
core is thought to be solid and primarily made up
of iron and some nickel. The outer core is all
around the inner core and is believed to be made
up of liquid iron mixed with liquid nickel. The
outer core is about 2890 to 5100 km. The inner
core is 5100 to 6378 km. Earths mantle is mainly
composed of substances high in iron and magnesium.
The melting point of every substance depends on
the pressure and ...

We live in an extraordinary era of exploration. We
are now able to reach far out into space and deep
down into the ocean. We have the advantage with
technology such as computers and satellites. We
can now simply understand the dynamic forces that
shape our Earth. Our Earth is constantly
destructing and recreating. It balances through a
continuous rebirth cycle. The Earth? s dynamic
shape can be summed up very simply-Transfer Of
Energy. This " Big Idea" helps to
explain many things such...

trembling or Natural Disasters earthquake,
trembling or shaking movement of the earths
surface. Most earthquakes are minor tremors.
Larger earthquakes usually begin with slight
tremors but rapidly take the form of one or more
violent shocks, and end in vibrations of gradually
diminishing force called aftershocks. The
subterranean point of origin of an earthquake is
called its focus; the point on the surface
directly above the focus is the epicenter. The
magnitude and intensity of an earthquake i...
