我将采摘,它告诉秘密并且使我脸红。[translate] aThey found water in tiny samples of magma,which was trapped in crystal。Magma is a rock made from cooled lava。 他们在岩浆微小的样品发现了水,在水晶被困住。岩浆是由冷却的熔岩做的岩石。[translate]...
What type of rock forms from the cooling of molten rock at or below the surface? Which statement is false concerning metamorphic rocks? a. Formed under enormous heat and pressure deep in Earth's interior b. Sometimes contain minerals segregated in wavy bands by folia...

Marbleis a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite. Which metamorphic ro...
Granite is an igneous rock that was formed from cooling magma. It contains lots of quartz, feldspar, and other minerals, giving it a distinctive look. Like quartzite, it’s mined in huge slabs. Appearance Appearance isn’t everything, but it significantly impacts your home’s resale value ...
If the acidic volcanic rock class rock has weak or does not have the negative anomaly, explained the rock magma has not been balanced with the plagioclase feldspar, it forms the depth to be supposed to be bigger than 50-60km, the existence adds the thick continental crust if has obvious ...
Komatiites' discovery was surprising in light of then-current geological theories about magmas, molten rock that forms in the Earth's mantle (the layer beneath the crust) and composes volcanic lava eruptions. Prior to 1960, geologists Bowen and Hess disagreed over whether or not the very high...
Before we continue, let's agree on some basics:calcium is an element, calcite and dolomite are minerals, and limestone is a sedimentary rock which can turn into the metamorphic rock called marble if the right conditions occur. Igneous rocks cool from molten magma and form the majority of the...
What kind of rock comes from a volcano? What is the center of a volcano called? What type of volcano is Mount Tambora? Which Cascade volcano will erupt next? What type of volcano is Mount Popocatepetl? What type of volcano is Mount Pinatubo? What are cracks in volcanoes called? Magma tha...
One assuming cause of the event involves massive coal burning, which led to extreme global warming and extinguished most life forms. The team set out to look for evidence of this theory and began to study the region of the Siberian Traps, where magma and lava (岩浆和熔岩)are known to ...
