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.Answer and Explanation: When magma cools, it creates igneous rock. Igneous is a word ...
What forms when magma cools? What is the effect of water on rock melting? What type of metamorphism does a meteorite impact cause? What process changes the grain size of a metamorphic rock? What kind of igneous rock usually contains large crystals?
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. ...
In simple terms, a rock is made up of two or more minerals and can also contain organic compounds.Rocks occurin different shapes, colors, weights, strengths, sizes, and texture. Rocks also change from one form to another and differ from one region to another because of the rock cycle. T...
If the magma cools down over a really long time, bigger crystals can grow. And then the rocks can look more speckled and multicoloured. Sounds: Music ends Nij: So is igneous rock only found near volcanoes? Heather: No, you can find igneous rocks in lots of places. And that's because...
What rock is shiny? Igneous rocksare formed when magma (molten rock deep within the earth) cools and hardens. Sometimes the magma cools inside the earth, and other times it erupts onto the surface from volcanoes (in this case, it is called lava). When lava cools very quickly, no crystals...
What type of rock is granite? Granite is anigneous rockthat forms when magma cools relatively slowly underground. It is usually composed primarily of the minerals quartz, feldspar, and mica. When granite is subjected to intense heat and pressure, it changes into a metamorphic rock called gneiss...
The geology of the Earth's surface is continually being shaped by volcanic activity. This natural process begins deep beneath the crust, when superheated magma (a liquid rock material made up of minerals and gases) rises toward the surface and erupts through cracks or vents. The molten rock re...
In that sense, Earth is probably unique. Although we may detect some life elsewhere, it will necessarily be completely different.从这个意义上说，地球可能是独一无二的。虽然我们可能会在其他地方发现一些生命，但那肯定是完全不同的。It was this mind-blowing series of improbable events that made Earth...
magma come out of solution, producing bubbles that are frozen in shape when the molten rock cools. Like pumice, scoria contains porous vesicles. However, the walls of the vesicles are thicker. Thus, scoria is darker in color (black, purplish red, dark brown) and more dense than water (...
