Explanation text : Volcano Eruption
Do you know what a volcano is? I guess you all know volcano is a mountain with magma inside it. Most volcanoes are formed on land, but there are some volcanoes that are on the ocean floor. You know the famous volcanoes in Indonesia, right? Yes, there are Mount Merapi and Mount Krakatau. Mount Merapi was erupt in October 2010 and Mount Krakatau was erupt in 1883. The eruptions are really massive and destructive. Do you want to know how is the volcano erupting? Well, let me explain to you.
At first, the eruption begins when pressure on a magma chamber inside the volcano forces magma up through the conduit and out the volcano's vents. Then, when the magma chamber has been completely filled, the pressure is getting higher. Finally, the magma reaches up to the surface. When magma reaches earth's surface it is called lava. It may pour out in gentle streams called lava flows or erupt violently into the air. Rocks ripped loose from the inside of the volcano or torn apart by the gas. may be shot into the air with the lava. The lava destroys everything in its path because it is very hot. The big rocks can destroy anything because the sizes are super big. The thick black smoke can burn everything slowly and it’s suffocating.
There’s no doubt that volcano eruption is really dangerous. Many people were dead because of it. A big number of people had to abandon their homes and land forever. Even the whole world's climate was changed for a while as a result of an eruption. But volcano eruptions bring good effects too, because after a long time it can make the land fertile.
