Question

An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter. What causes earthquakes and where do they happen?

The earth has four major layers: the inner core, outer core, mantle and crust. (figure 2) The crust and the top of the mantle make up a thin skin on the surface of our planet. But this skin is not all in one piece – it is made up of many pieces like a puzzle covering the surface of the earth. (figure 3) Not only that, but these puzzle pieces keep slowly moving around, sliding past one another and bumping into each other. We call these puzzle pieces tectonic plates, and the edges of the plates are called the plate boundaries. The plate boundaries are made up of many faults, and most of the earthquakes around the world occur on these faults. Since the edges of the plates are rough, they get stuck while the rest of the plate keeps moving. Finally, when the plate has moved far enough, the edges unstick on one of the faults and there is an earthquake. Why does the earth shake when there is an earthquake?

While the edges of faults are stuck together, and the rest of the block is moving, the energy that would normally cause the blocks to slide past one another is being stored up. When the force of the moving blocks finally overcomes the friction of the jagged edges of the fault and it unsticks, all that stored up energy is released. The energy radiates outward from the fault in all directions in the form of seismic waves like ripples on a pond. The seismic waves shake the earth as they move through it, and when the waves reach the earth’s surface, they shake the ground and anything on it, like our houses and us!

Soal menanyakan, "Teks tersebut berbicara tentang apa?"

Topik pembahasan teks dapat ditemukan pada pikiran utama teks. Pikiran utama teks dapat ditemukan pada awal kalimat teks atau akhir kalimat teks.

Pada awal kalimat teks soal tertulis;

"An earthquake is what happens when two blocks of the earth suddenly slip past one another." (Gempa bumi adalah apa yang terjadi ketika dua blok bumi tiba-tiba tergelincir satu sama lain.)

Dari kutipan teks, kita tahu bahwa teks berbicara tentang gempa bumi (an earthquake).

Jadi, jawaban yang benar adalah: The text is about an earthquake.
