How Earthquakes Happen

    Earthquake is one of the most destroying natural disasters. Unluckily it often happens in several regions. Recently a horrible earthquake has shaken West Sumatra. It has brought great damages. Why did it occur? Do you know how an earthquake happens?

     Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves. It make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. They don't just slide smoothly. The rocks are still pushing against each other, but not moving. After a while, the rocks break because of all the pressure that's built up. When the rocks break, the earthquake occurs.

     During the earthquake and afterward, the plates or blocks of rock start moving, and they continue to move until they get stuck again. The spot underground where the rock breaks is called the focus of the earthquake. The place right above the focus is called the epicenter of the earthquake.

DISCUSSION

The Pros and Cons of School Uniform

    School uniforms are dress codes that are determined by the teaching institutions and students has to follow the designed code obediently everyday. Many people believe that school uniforms should be applied but the others don't.

    Uniforms have various advantages for both the family and the child. A united school apparel can relief a financial stress of the backs of many families. As kids tend to compete and imitate each other, the race of following new trends in fashion or, providing different attire for every school day is considered a financial burden, not every family can afford it. 

    Additionally, a uniform creates a sense of equality between all pupils. Young kids tend to judge others according to their look and what they wear. Uniting their school attire will draw their attention to other criteria and, the only advantage of one student over another would be personality, academic achievement or being good at sports. On the other hand, as repetition can lead to boredom, children can get frustrated of wearing same thing to school every day. Also, prevent their first steps of individuality by taking away their right to choose what to wear on their own free well.

    In conclusion, I believe uniforms aren’t meant to suppress the creativity or freedom of children. It helps redirecting kids’ creativity towards more important things than outer look, and waive financial burden of their families.
