Mantle is a largest part of Earth, 3000 km thick. Magma is molted material with high portion of SiO2 conponent. There fore, magmatic rocks are consistrd of si locate minerals. Magma is called lava when om surface. Most eruptions are caused by significant amount of water sliding down to volcanic crater, later when heated working as a fuel for eruption. In such cases, eruption trows rocks, vapor and lava onto surface. But, rearest and deadliest type of eruption is a hot spot eruption. It occurs when there is high concentration of ultramafic magma in a buble (gigant one), much hotter and less dense than sorounding magma. In such casec, eruption brings mostly lava, only small portion of rocks and vapor.

Magma is molted material consisting of most common elements that form all the minerals (crystals) on Earth’s surface while mantle is a part of Earth (largest one in volume). It would be right to say that Earth’s mantle is about 3000 km thick layer of molted material (magma) with high concentration of Si. There fore, magmatic rocks have so much SiO2 components, whether in form of quartz or other silicatic minerals with SiO2 component. There are many for s of eruption, most of them are caused by certain amount of water falling down to crater, than causing rapid heating where later water steam works as a fuel for volcanic eruption. Them, cooled rocks, lava (magma but outside) and vapor are injected into atmosphere. But, there is that finala, deadliest
