The document contains explanations of two natural phenomena: 1) It explains tsunamis as series of waves generated by rapid displacement of large volumes of water, often caused by earthquakes or landslides, and how they radiate across oceans and cause damage upon reaching land. 2) It explains the water cycle as the continuous movement of water on Earth through evaporation, condensation, precipitation, and flow towards oceans, where the cycle repeats as heat from the sun evaporates water again.

6. Tsunami

7. General Statement
The term of “tsunami” comes from the japanese which
means harbour “tsu” and wave “nami”. A tsunami is series of
waves generated when water in a lake or the sea is rapidly
displaced on a massive scale.

8. Sequenced Explanation
A tsunami can be generated when the sea floor abruptly
deforms and vertically displaces the overlyng water. Such large
vertical movements of the earth’s crusht can occur at plate
boundaries.
Subduction of earthquakes are particulerly effective in
generating tsunamis, and occur where denser oceanic plate slim
under continental plates.

9. As the displaced water mass moves under the influence or
gravity to regain its equilibrium, it radiates across the ocean
like ripples on a pond.

10. Conclusion
Tsunamis always brine 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.

11. Water Cycle

12. General Statement
The water cycle is the never-ending movement of the
earth’s water. Water goes from the ocean to the air, to the
land, and back to the oceans again. For that reason, its
movement is called a cycle.

13. Sequenced Explanation
This cycle begins when heat from the sun turns ocean
water into water vapor. Water vapor is water that has become a
gas. The water vapor rises high into the sky, where it cools off.
The cooled water vapor changes into tiny drops of water. The
drops are held up in the sky by rising warm air. When billions
of these drops of water cluster together they form a cloud. The
water in the clouds eventually falls to earth as rain. If the
water vapor is cold enough, it turns into ice and falls as snow.

14. Conclusion
Most rain and snow falls into the ocean, but some falls on
land. In time, this water also flows back to the ocean and the
cycle starts again.
