What forms when magma cools? Magma Transformation: Magma is molten rock and can be found below the Earth's surface and above the Earth's surface. When above, it is called lava. Magma can cool when it's both inside the Earth and outside the Earth. ...

Any rock that forms from the cooling of magma is an igneous rock.Magma that cools quickly forms onekind of igneous rock, and magma that cools slowly forms another kind. When magma rises from deep within the earth and explodes out of a volcano, it is called lava, and it cools quickly on...
Following a large caldera-forming eruption some magma remains in the magma reservoir.This magma cools, its viscosity increases, and when new magma is injected, the magma left over after the caldera-forming eruption stops the fresh magma from propagating to the surface and promotes caldera resurgence...
Volcanoes are formed when___. A. stars shine brightly B. magma cools and hardens C. butterflies dance D. rivers flow quickly 相关知识点: 试题来源: 解析 B。解析:火山是当岩浆冷却并变硬时形成的。选项 A 星星明亮地闪耀与火山形成无关;选项 C 蝴蝶跳舞不会形成火山;选项 D 河流快速流动也不会...
Lava rock, also known asigneous rock, is formed when volcanic lava or magma cools and solidifies. It is one of the three main rock types found on Earth, along with metamorphic and sedimentary. What is hard lava called? When magma reaches the surface it is then called lava and the erupt...
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 ...
very hot magma. very hot magma. Chill zone or chill margin Chill zone or chill margin: At the contact with country rock, magma cools : At the contact with country rock, magma cools quickly due to the heat loss from the magma chamber into the country rock. quickly due to the heat loss...
creating new crust material. Divergent plate boundaries often occur under the ocean. As the magma cools underwater it forms basalt, which makes up the majority of the oceanic crust. Examples of divergent faults include the Mid-Atlantic Ridge, a “crack” in the Atlantic Ocean where molten rock...
