The most common causes of tsunamis are underwater earthquakes. To understand underwater earthquakes, you must first understand plate tectonics. The theory of plate tectonics suggests that the lithosphere, or top layer of the Earth, is made up of a series of huge plates. These plates make up the continents and seafloor. They rest on an underlying viscous called the asthenosphere. Think of a pie cut into eight slices. The pie crust would be the lithosphere and the hot, sticky pie filling underneath would be the asthenosphere. On the Earth, these plates are constantly in motion, moving along each other at a speed of 1 to 2 inches (2.5-5 cm) per year. The movement occurs most dramatically along fault lines (where the pie is cut). These motions are capable of producing earthquakes and volcanism, which, when they occur at the bottom of the ocean, are two possible sources of tsunamis. When two plates come into contact at a region known as a plate boundary, a heavier plate can slip under a lighter one. This is called subduction. Underwater subduction often leaves enormous "hand prints" in the form of deep ocean trenches a long the seafloor. In some cases of subduction, part of the seafloor connected to the lighter plate may "snap up" suddenly due to pressure from the sinking plate. This result in an earthquake. The focus of the earthquake is the point within the Earth where the rupture first occurs, rocks break and the first seismic waves a re generated. The epicenter is the point on the seafloor directly above the focus. When this piece of the plate snaps up and sends tons of rock shooting upward with tremendous force, the energy of that force is transferred to the water. The energy pushes the water upward above normal sea level. This is the birth of a tsunami. The earthquake that generated the December 26, 2004 tsunami in the Indian Ocean was a 9.0 on the Richter scale - one of the biggest in recorded history. The following is mention~d in the text about tsunami, EXCEPT that they are .. . A. predictable following any incidence of earthquakes B. close to the rise of sea levels from the sinking plate C. connected to deep ocean trenches along sea floors D. related to strong movement of plate tectonics E. highly linked to underwater earthquakes

Hai! Kakak bantu jawab yaa. Jawaban yang benar adalah: C. connected to deep ocean trenches along sea floors Soal ini meminta kita untuk mencari pernyataan yang TIDAK disebutkan dalam teks tentang tsunami. Mari kita identifikasi masing-masing opsi: A. Predictable following any incidence of earthquakes. (Dapat diprediksi setelah terjadinya gempa bumi.) Pernyataan ini BENAR. Terdapat info di bacaan, yaitu: The most common causes of tsunamis are underwater earthquakes. (Penyebab tsunami yang paling umum adalah gempa bumi bawah laut.) B. Close to the rise of sea levels from the sinking plate. (Dekat dengan kenaikan permukaan laut dari lempeng yang tenggelam.) Pernyataan ini BENAR. Terdapat info di bacaan, yaitu: In some cases of subduction, part of the seafloor connected to the lighter plate may "snap up" suddenly due to pressure from the sinking plate. This result in an earthquake. (Dalam beberapa kasus subduksi, bagian dari dasar laut yang terhubung ke pelat pemantik mungkin "terbentur" secara tiba-tiba karena tekanan dari pelat yang tenggelam. Hal ini mengakibatkan gempa bumi.) C. Connected to deep ocean trenches along sea floors. (Terhubung ke parit laut dalam di sepanjang dasar laut) Pernyataan ini SALAH. Yang berhubungan dengan parit laut adalah subduksi, bukan tsunami. Terdapat info di bacaan, yaitu: Underwater subduction often leaves enormous "hand prints" in the form of deep ocean trenches a long the seafloor. In some cases of subduction, part of the seafloor connected to the lighter plate may "snap up" suddenly due to pressure from the sinking plate. This result in an earthquake. (Subduksi bawah air sering kali meninggalkan "jejak tangan" yang sangat besar dalam bentuk parit laut dalam di sepanjang dasar laut. Dalam beberapa kasus subduksi, bagian dari dasar laut yang terhubung ke pelat pemantik mungkin "terbentur" secara tiba-tiba karena tekanan dari pelat yang tenggelam. Hal ini mengakibatkan gempa bumi.) D. Related to strong movement of plate tectonics. (Terkait dengan kuatnya pergerakan lempeng tektonik.) Pernyataan ini BENAR. Terdapat info di bacaan, yaitu: The most common causes of tsunamis are underwater earthquakes. (Penyebab tsunami yang paling umum adalah gempa bumi bawah laut.) E. Highly linked to underwater earthquakes. (Sangat terkait dengan gempa bumi bawah laut.) Pernyataan ini BENAR. Terdapat info di bacaan, yaitu: The most common causes of tsunamis are underwater earthquakes. (Penyebab tsunami yang paling umum adalah gempa bumi bawah laut.) Dengan demikian dapat kita simpulkan bahwa pernyataan yang salah ada pada opsi C. Jadi, jawaban yang benar adalah: C. connected to deep ocean trenches along sea floors Semoga membantu yaa.
