Magma originates inthe lower part of the Earth's crust and in the upper portion of the mantle. Most of the mantle and crust are solid, so the presence of magma is crucial to understanding the geology and morphology of the mantle. Where does magma come from and how does it form? Magma ...
Where does all that lava come from?We asked Gabi Laske, a geophysicist at the University of California-San Diego who led one of the first projects to map the deep plumbing that feeds the Hawaiian Islands' volcanoes, to explain. Where is the magma surfacing at Mauna Loa coming from?
Two gemstones, diamonds and peridot, are found much deeper in the Earth. Diamond forms in “kimberlite pipes” that originate in the Earth’s mantle (>125 miles) and end at the surface. Molten magma running through these pipes usually reaches the surface as lava and cools off, but if it...
The locationbeneath the vent of a volcanowhere molten rock (magma) is stored prior to eruption. Also known as a magma storage zone or magma reservoir. What is the storage of magma? Magma forms above the subducting slab of oceanic crust and accumulates at the base of Earth's rigid crust b...
Where does sea level rise occur? Where does contact metamorphism occur? Where do fire tornadoes mostly occur? Subduction occurs when Where does basaltic magma form? How does gully erosion occur? When did the Ouachita orogeny occur? Where does groundwater come from?
Educational providers are creating coursework and materials that give teachers new ways to express and participate in classrooms; imagine that instead of building a papier-mâché model of a volcano you could virtually experience being the magma that’s ejected into the atmosphere. In heavy industrie...
In this case, the reason was the impact of a celestial body, but most nickel-bearing sulfidic ores were created through the cooling of magma. Besides nickel, they also contain copper, cobalt, and metals of the platinum group, such as palladium or iridium. This means that the same ore (...

Even as you are reading this, magma from beneath the lithosphere is rising up to form new crust on the ocean floor. This process creates the longest mountain ranges in the world and contributes to our ever-shifting Earth.Answer and Explanation: ...
