Detailed explanation-1: -Much of the planet’s mantle consists of magma. This magma can push through holes or cracks in the crust, causing a volcanic eruption. When magma flows or erupts onto Earth’s surface, it is called lava. Like solid rock, magma is a mixture of minerals.
Detailed explanation-2: -The rocks that make up Earth’s mantle are mostly silicates-a wide variety of compounds that share a silicon and oxygen structure. Common silicates found in the mantle include olivine, garnet, and pyroxene. The other major type of rock found in the mantle is magnesium oxide.
Detailed explanation-3: -The molten material in the mantle of the Earth is called magma. Sometimes when magma breaks the surface, as in volcanic eruptions, it is called lava.
Detailed explanation-4: -Felsic and mafic magmas are common and are high in silica, but vary in viscosity and their composition of other elements like iron. Both these magmas can form around subduction zones or rising mantle plumes.
Detailed explanation-5: -Magma is derived from partial melts of existing rocks in Earth’s mantle. Complete answer: Igneous rock or magmatic rock is made up of molten magma. It is one of the three main rock types; sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of lava.
