Volcano Eruptions We live on the crust of the earth. Beneath the crust is a layer of rock called the mantle. Inside the mantle is the earth's core. Magma, or melted rock, and gas are trapped in the core. A volcanic eruption occurs when magma from deep inside the earth pushes up through the mantle and the crust. Volcanic eruptions can cause fires, mudslides, floods, avalanches, and earthquakes. Even a sudden volcano eruption can kill many people. A volcanic eruption begins with the formation of magma in the lower sections of the Earth's crust and the upper region of the mantle. With pressure driving the magna, it travels upward with tremendous force. If it is halted in a magma chamber, the pressure will begin to increase. Eventually, the solid rock and other material surrounding the chamber will crack, creating a new passage to the earth's surface. The magma will then flow through this conduit until it reaches the surface, where it will spew out in a volcanic eruption. When magma reaches the surface, it erupts as lava, ash, and volcanic rocks. Magma that reaches the earth's surface is called lava. Steam and gases, such as carbon dioxide, are also released into the atmosphere during a volcanic eruption. Lava flows can reach speeds of 90 to 100 miles per hour as they slide down the side of a volcano. These kinds of eruptions can push down entire forests. They can change the course of rivers. They affect the air we breathe, the food we eat, and the water we drink. Taken from: Many Sources B. Answer the following questions based on the text above! 2. Explain in brief about how volcano eruptions erupt!

Hai Diandra, kakak bantu jawab yaa. Jawaban dari soal ini adalah "Volcanic eruptions start when magma in the Earth's crust is pushed up by great pressure. As a result of too much pressure, rock and material will crack and cause magma to reach the surface which eventually becomes a volcanic eruption." Perintah dari soal adalah menjelaskan secara singkat bagaimana gunung berapi meletus. Berikut adalah bagaimana proses terjadinya letusan gunung api, "A volcanic eruption begins with the formation of magma in the lower sections of the Earth's crust and the upper region of the mantle. With pressure driving the magma, it travels upward with tremendous force. If it is halted in a magma chamber, the pressure will begin to increase. Eventually, the solid rock and other material surrounding the chamber will crack, creating a new passage to the earth's surface. The magma will then flow through this conduit until it reaches the surface, where it will spew out in a volcanic eruption." Terjemahan proses di atas adalah sebagai berikut: Letusan gunung berapi dimulai dengan pembentukan magma di bagian bawah kerak bumi dan bagian atas mantel. Dengan tekanan yang mendorong magma, ia bergerak ke atas dengan kekuatan yang luar biasa. Jika dihentikan di dapur magma, tekanannya akan mulai meningkat. Akhirnya, batuan padat dan material lain yang mengelilingi ruangan itu akan retak, menciptakan jalur baru ke permukaan bumi. Magma kemudian akan mengalir melalui saluran ini hingga mencapai permukaan, di mana ia akan memuntahkan letusan gunung berapi. Secara singkat, dapat disimpulkan bahwa letusan gunung berapi dimulai dari magma di kerak bumi yang didorong ke atas oleh tekanan yang besar. Akibat tekanan yang terlalu besar, batuan dan material akan retak dan menyebabkan magma mencapai permukaan yang akhirnya menjadi letusan gunung berapi. Jadi, jawaban yang tepat adalah "Volcanic eruptions start when magma in the Earth's crust is pushed up by great pressure. As a result of too much pressure, rock and material will crack and cause magma to reach the surface which eventually becomes a volcanic eruption." (letusan gunung berapi dimulai dari magma di kerak bumi yang didorong ke atas oleh tekanan yang besar. Akibat tekanan yang terlalu besar, batuan dan material akan retak dan menyebabkan magma mencapai permukaan yang akhirnya menjadi letusan gunung berapi.) Semoga membantu.
