Magma The precursor to lava when still underground. If the magma rises, it can lead to an eruption. 1 Lava A hot substance that emerges from volcanoes and cools to form rock. The island was formed by layers of lava over time. 4 Magma Magma (from Ancient Greek μάγμα (mágma) ...
When magma (the molten liquid inside of volcanoes) cools, it forms igneous rock. Though their formation may be similar, igneous rocks can look and feel quite different. Phaneritic rocks are coarse, while aphanitic rocks have a much finer grain and are smoother. ...
When a planet gets big enough, when it acquires enough mass, it migrates inwards towards the star. Understanding this phenomenon was a real revolution.当一颗行星变得足够大，当它获得足够的质量时，它会向恒星内部迁移。理解这一现象是一场真正的革命。Planetary migration explains why the majority of ...
Magma is a mixture of molten and semi-molten rock beneath the surface of the Earth that can cause an eruption when it finds its way to the surface, becoming lava. If the magma erupts beneath the sea, it will be more explosive than if it erupts on land, experts say, though an erupti...
What happens to a substance when it melts? When a substance melts, it transitions from a solid state to a liquid state. 2 Is "molten" a permanent state? No, "molten" is a temporary state; the substance solidifies again as it cools. 2 Share Your Discovery Share via Social Media Embed...
ropy "pahoehoe" lava (pronounced "pah-HOY-hoy"). It has the consistency of molten peanut butter. It cools very quickly to make thick black rock layers. The other type of lava that flows from volcanoes is called "A'a" (pronounced "AH-ah"). It looks like a moving pile of coal c...
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 ...
like iron and copper.When the water shoots up and re-enters the cold ocean, it quickly cools and these minerals precipitate out.They’re released and they are deposited into the ocean water, which affects its composition.And it also creates quite a site, these vents have a plume that looks...
