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:1 When magma cools, it creates igneous rock. Igneous is a word...
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...
What is extrusive igneous rock? Igneous Rocks: Igneous rocks are formed when lava or magma cools, allowing the elements inside to crystallize. Igneous rocks are one of the three major groupings of rocks. Answer and Explanation:1 Extrusive igneous rocks are rocks that are formed by lava that ...
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. ...
There are three kinds of rock: igneous, sedimentary, and metamorphic. Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocksoriginate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. ...
Is Basalt made of lava? Basalt is themost common composition of lava rocksthat cool from magma, liquid rock that rises from the deep Earth at volcanoes. What two minerals are in Basalt? Basalt is mainly made of two minerals:Plagioclase feldspar and pyroxene. ...
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 (...
When the magma breaks through Earth's surface, the confining pressure on the gas is suddenly removed. The release of confining pressure causes the gas to expand as an explosive eruption that launches a spray of molten rock into the air. The molten rock cools as it flies through the air, ...
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...
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 erup...
