Today, a volcano is the term for any place on the surface of the earth, where hot molten rock or magma is erupted or has been in the past.Try our free app!Android | iOS versionGuaranteed tours 9-25 Jun 2025: Volcanoes and Spices - Sulawesi/Halmahera (Indonesia) 7-22 Jul 2025: From...
At this point, the magm a breaks through the surface —sometimes in a great explosion(爆炸) — at which point it is called lava(岩浆,火山岩).The temperature inside a volcano is very hot. Scientists say it can get as hot as 2, 120degrees Fahrenheit. Molten(熔化的) rock turns an orang...
Magma is hot, molten material that comes from within Earth's mantle or crust and is forced out as lava during volcanic eruptions. It typically contains silicates, suspended crystals and dissolved gases [source: Oxford Dictionary of Science]. Another common categorization, called the Volcano Explos...
Our Earth is constantly changing its form and landscape, due to the fact that the inside of the planet contains molten rock. Volcanoes are one such feature on the Earth's crust that shows how things can change in a moment. Answer and Explanation:1 ...
Unlike volcanoes associated with plate boundaries, hotspot, or inter-plate, volcanoes are located within tectonic plates. They are fueled by localized sources of high heat energy known as thermal plumes. These plumes of molten rock, called magma, rise from the lower asthenosphere. They are much ...
Most composite volcanoes are found in the so-called Ring of Fire, an area in the Pacific basin. What is the difference between a stratovolcano and volcano? Volcanoes are vents found in the crust of planets and satellites from which molten rocks, gas, and lava erupt. There are three types...
What can be found inside a coprolite? When molten rock cools it becomes what kind of rock? What type of igneous rock is diorite? What is geological exploration? Sandstone is an example of what type of rock? What type of igneous rock is granite?
Yellowstone sits above a spot in the Earth's mantle where columns of hot, molten rock called plumes rise to form volcanoes in the planet's crust. This spot is called a hotspot, and it creates atype of volcano not associated with a plate boundary. Yellowstone has produced three calderatypes...
the lava comes up from the mantle (which is the layer under the surface). Once there's enough molten rock — called magma — and enough pressure on it, a volcanic eruption occurs. In many volcanoes, the magma rises up through a central tube or "throat," and emerges out the top of ...
magma (molten rock). Magma above a subducting slab will rise into the crust and form an arc of volcanoes, according toColumbia Universityin New York City. (The hot, molten magma rises because it is less dense and more buoyant than the rock around it, according to theArizona Geological ...
