The magma inside a volcano contains water, which heats up and turns into steam. As the steam pressure builds, it violently erupts from the crater, causing an explosive eruption.<\/p>\n<p><span style=\"font-size: 14px;\">Thinking about everyday food in relation to natural phenomena makes science much more interesting! By the way, I once observed popcorn in a science club experiment. We used this &#8220;<\/span><a style=\"text-align: center;\" href=\"https:\/\/amzn.to\/41BV1Kz\">JAZZ POPCORN<\/a>&#8221; for the experiment. We roasted it over a lab burner with a wire mesh, and the popcorn came out perfectly fine.<\/p>\n<h3>Carbonated Drinks and Mochi<\/h3>\n<p class=\"p1\">Similar phenomena include the fizzing of a carbonated drink when you open the lid, and how mochi swells up when heated because the water inside turns into steam.<\/p>\n<p class=\"p1\">The same thing actually happens inside magma. Magma deep underground is under immense pressure, and a lot of volcanic gases (mostly water vapor and carbon dioxide) are dissolved in it. However, as the magma rises closer to the surface, the surrounding pressure decreases. The volcanic gases can no longer stay dissolved and form bubbles.<\/p>\n<p class=\"p1\">This is the same principle as when you open a bottle of soda; the pressure inside the bottle drops, and the dissolved carbon dioxide gas escapes as bubbles. This gas formation causes the magma to expand, which can lead to volcanic eruptions. The connection between soda and volcanoes is a bit unexpected, isn&#8217;t it?<\/p>\n<h3>How Magma is Formed<\/h3>\n<p class=\"p1\"><span class=\"s1\">The Earth&#8217;s surface is made up of several <\/span><b>plates (giant slabs of rock) that fit together. These plates move slowly, and sometimes one plate can subduct, or sink, beneath another<\/b><span class=\"s1\">.<\/span><\/p>\n<p class=\"p3\">When this happens, there&#8217;s a layer of <b>mantle<\/b> (which makes up about 80% of the Earth&#8217;s volume) directly above the sinking plate. The mantle is made of rock, but it has the unique characteristic of <span class=\"s2\"><b>flowing very slowly due to heat<\/b><\/span> (<strong>it&#8217;s solid, but it moves!<\/strong>). As a plate subducts, it drags the mantle with it. But this creates an empty space, right? To fill that space, <span class=\"s2\"><b>hot mantle from deeper down rises up<\/b><\/span>.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-47880 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2025\/03\/d9d30a23f1d92591ecad040269088e04.jpg\" alt=\"\" width=\"460\" height=\"329\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2025\/03\/d9d30a23f1d92591ecad040269088e04.jpg 1390w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2025\/03\/d9d30a23f1d92591ecad040269088e04-300x215.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2025\/03\/d9d30a23f1d92591ecad040269088e04-1024x732.jpg 1024w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2025\/03\/d9d30a23f1d92591ecad040269088e04-768x549.jpg 768w\" sizes=\"auto, (max-width: 460px) 100vw, 460px\" \/><\/p>\n<p style=\"text-align: center;\">Reference: <b style=\"font-size: 14px;\">\u300e<a href=\"https:\/\/amzn.to\/4ijQUtL\">Understanding Volcanoes<\/a>\u300f<\/b><span style=\"font-size: 14px;\">by Masaki Takahashi, Seibundo Shinkosha, 2016<\/span><\/p>\n<p class=\"p3\">Furthermore, the surface of the subducting plate was originally exposed to seawater. As a result, the plate contains a lot of water. As it sinks, this water is released from the plate and seeps into the surrounding mantle. The important thing here is that water has the property of making rocks easier to melt. When water is added, the hot mantle melts and becomes magma. Magma is molten rock that has melted into a liquid state deep underground due to heat. Its temperature can exceed 1000\u00b0C.<\/p>\n<p class=\"p3\">Magma is lighter than the surrounding rock, so it moves upward. When it breaks through the Earth&#8217;s crust and reaches the surface, a volcanic eruption occurs. This is how volcanoes are formed. In other words, the birth of a volcano is deeply connected to the movement of plates and the function of the mantle!<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-47877 aligncenter\" src=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2025\/03\/f0b1764d4304510e9e12058cbd74fbe9.jpg\" alt=\"\" width=\"232\" height=\"143\" srcset=\"https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2025\/03\/f0b1764d4304510e9e12058cbd74fbe9.jpg 1566w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2025\/03\/f0b1764d4304510e9e12058cbd74fbe9-300x185.jpg 300w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2025\/03\/f0b1764d4304510e9e12058cbd74fbe9-1024x630.jpg 1024w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2025\/03\/f0b1764d4304510e9e12058cbd74fbe9-768x473.jpg 768w, https:\/\/phys-edu.net\/wp\/wp-content\/uploads\/2025\/03\/f0b1764d4304510e9e12058cbd74fbe9-1536x946.jpg 1536w\" sizes=\"auto, (max-width: 232px) 100vw, 232px\" \/><\/p>\n<p style=\"text-align: center;\"><a href=\"https:\/\/amzn.to\/4ijQUtL\">Also check out this &#8220;Understanding Volcanoes&#8221; book on Amazon.<\/a><\/p>\n<h3>Contact and Requests<\/h3>\n<p>Let&#8217;s make the wonders and fun of science more accessible!
