3. Explanation is a text which tells
processes relating to forming of natural,
social, scientific and cultural phenomena.
Explanation text is to say ‘why’ and ‘how’
of the forming of the phenomena. It is
often found in science, geography and
history text books.

4.  Generic structure of Explanation : stating
the phenomenon issues which are to be
explained.
 A Sequenced of Explanation : A sequenced
explanation of why or how something occurs

5.  Focus on generic, non-human participants

 The use of action verbs
 The use of simple present tense

 The use of technical language

6. The term of “tsunami” comes from the Japanese
which means harbour ("tsu") and wave ("nami"). A tsunami
is a series of waves generated when water in a lake or a
sea is rapidly displaced on a massive scale.
A tsunami will be generated when the seafloor
abruptly deforms and vertically displaces the overlying
water. Such large vertical movements of the earth's crust
can occur at plate boundaries.
Subduction of earthquakes are particularly effective
in generating tsunami, and occur where denser oceanic
plates slip under continental plates.
As the displaced water mass moves under the
influence of gravity to regain its equilibrium, it radiates
across the ocean like ripples on a pond.
Tsunami always bring great damage. Most of the
damage is caused by the huge mass of water behind the
initial wave front, as the height of the sea keeps rising fast
and floods powerfully into the coastal area.
