Question

Earthquakes are the vibrations caused by rocks breaking under stress. The underground surface The size or magnitude of earthquakes is determined by measuring the amplitude of the seismic waves recorded on a seismograph from the earthquake These are put into a formula which converts them to a magnitude, which is a measure of the energy released by the earthquake. For every unit increase in magnitude, there is roughly a thirty-fold increase in the energy released. along which the rock breaks and moves is called a fault plane A magnitude 8,6 earthquake releases energy equivalent to about 10.000 atomic bombs of the type developed in World War II. Fortunately, smaller earthquakes occure much more frequently than large ones and most cause little or no damage Earthwuake magnitude was traditionally measured on the Richter scale. It is often now calculated from seismic moment, which is proportional to the fault area multiplied by the average displacement on the fault The focus of an earthquake is the point where it originated within the earth. The earthquake epicente is the point on the Earth's surface directly above the focus. 16. What is the main topic of the text above? A. Earthquake B. Earthquake cause. C. Earthquake power. D. Earthquake effects

D. Nur · Accepted Answer

Halo, Anonim. Kakak bantu jawab, ya.

Jawaban untuk soal ini adalah C. Earthquake power.

Soal ini menanyakan topik atau inti bahasan dari teks yang tertera.

Untuk menjawab soalnya, perhatikan beberapa kalimat 1 dan 2 berikut:

- Kalimat 1:
"Earthquakes are the vibrations caused by rocks breaking in the underground surface" artinya "Gempa bumi adalah getaran yang disebabkan oleh retakan batuan di bawah tanah".

Kalimat 2:
"The size or magnitude of earthquakes is determined by measuring the amplitude of the seismic waves recorded on a seismograph from the earthquake" artinya "Besar kekuatan gempa ditentukan dengan mengukur amplitudo gelombang seismik dari gempa bumi yang terekam di seismograf".

Berdasarkan arti dua kalimat tersebut, dapat ditentukan bahwa teks di soal ini intinya membahas tentang besar-kecilnya kekuatan gempa bumi. Ini sesuai dengan opsi C.

Jadi, jawaban untuk soal ini adalah C. Earthquake power.
