Explanation Text

"Tsunami"

A tsunami is a natural disaster that is a series of waves that move quickly in the ocean caused by strong earthquakes, volcanic eruptions, landslides, or just asteroids or meteors in the ocean. The term of “tsunami” comes from the Japanese which means harbour (“tsu”) and wave (“nami”). 

      Tsunamis have very long wavelengths. This can be hundreds of kilometers long. Usually, tsunamis start suddenly. Waves travel at high speed across the ocean with little loss of energy. They can remove sand from the beach, destroy trees, throw and drag vehicles, homes, and even destroy entire cities. 

       In the depths of the ocean, tsunami waves do not dramatically increase. But as the waves move inland, they build to higher and higher heights as the depth of the sea decreases. The speed of a tsunami wave depends on the depth of the sea and not the distance from the source of the wave. 

        Tsunami waves can move as fast as jets over deep waters, only slowing when they reach shallow waters.Tsunamis cannot be prevented. However, there are ways to help stop people dying from a tsunami. Like issuing a warning sonar before the big waves reach the shore. Because the earthquake that caused the tsunami could be felt before the waves reached the shore, people could be warned to go somewhere safe.

Cause and Effect

"Cause and Effect of Jealousy"

Jealousy is an emotion that is inherent in humans. Jealousy usually makes people greedy and controlled by one's own perspectives. 

Cause of jealousy include :

1. Dissatisfaction.
2. Comparison to others. 
3. Pride. 
4. Low self-esteem. 
5. Desire for worldly gain. 

The effect of jealousy involves an individual having a desire for what another person has.  When this feeling is not controlled or tended to, it develops into disdain or scorn for the other person simply because they remind the individual of what they are lacking.  If uncontrolled, the feeling can also lead to malice, in which the individual wishes to destroy the good in the other person’s life.  This is done with the idea that if the individual cannot experience the pleasure that the person has from that good, then that person shouldn’t be able to either.

Personal Letter

Dear friend, Sadana.

    It's been a long time since the last time I wrote a letter for you after 2 years. I have know you in the first of middle school. We used to be friends because have a same hobbies and sometimes have same opinions. Sadly we're not enter the same high school, so we're not together this time.

   In my school I learn about SDG program. I don't know about what is that before, but after I know i little bit interest about that, especially about Life on Land program.  You know about what happened in Australia, right? It's so sad many forest destroy. Pollution everywhere, many animal death and losing place to life.

   So because of that I started interests about SDG, especially about life on Land program. What about you? About your school? Do you learn about SDG in your school too? Please tell me. I hope you always happy and life peacefully.


Your friends
