What is a low-silica magma?
A magma containing not much silica (= SiO2). For example: a basaltic magma. These magma's have a low viscosity since the lower the SiO2-content, the lower the viscosity; and hence flow easily (↔ a felsic magma).
What natural resources are formed by magma?
It can make obsidian if it mixes with sand but mainly makes different forms of stone
What the same about silica rich and silica poor magma?
Silica is a natural element found within the Earth's crust. There are several different types of it. Silica gets inside magma when a volcano forms. During the formation, the magma from deep inside the Earth pushes its way up to the surface. As it progresses upward, it passes through the continental crust, or layer of crust below Earth's continents. Silica is abundant in that area. While the magma is in the continental crust, even if only for a little while, it mixes with the silica. Some parts of the continental crust aren't quite as plentiful in silica as others. Depending on the amount of silica mixed with the magma, the magma can become 'silica-rich', or have sufficient amounts of silica. This lavish amount of silica in the magma makes the magma thick and pasty. Then, when the volcano goes to erupt, the magma gets stuck in the caldera, or crater hole in the top of the volcano, because of its thickness. Pressure builds up behind the plugged exit, as more gas and magma yearns to escape. Eventually, this pressure builds up SO much that the magma cork gives way, allowing all the gases and lava to burst out of the volcano in a GIGANTIC eruption. This is why an explosive eruption has so much smoke, from the gas build-up inside of the volcano. Quiet eruptions don't because there is no gas pressure to stop the thin magma from leaking out of the hot spot/volcano. In conclusion, silica creates a thick magma. This results in a plugged caldera. Gas pressure within the volcano then builds up because of the thick magma cork. When the cork gives way, a HUGE eruption results, releasing all the gases and smoke. Hope that this explanation helped!
What are the 3 stages in the formation of volcano?
When a continental plate and an oceanic plate move toward each other and collide, the edge of the oceanic plate goes down into the part of the mantle which consists of molten rocks. At a depth of 125 to 160 km below the earth's surface, the heat is so great that the rock which goes down is partially melted. This partial melting of rocks generates magma. The downgoing rocks also brings water. The other materials in the mantle interact with the water and also generate magma. Magma has lower density than the surrounding rocks. The gas from the melting rock which mixes with the magma makes it rise. As magma rises, it melts its way through the surrounding rocks and forms a large chamber where magma is stored until it finds it way out to the earth's surface.
Why some volcanic eruptions are very explosive and others are less explosive?
It all depends on the consistency of the magma and the temperature of the magma. The thicker the magma is, the quieter the eruption. If the magma is thinner, the eruption will be more violent.
Compare and contrast the three types of magma?
Basaltic Magma is typically forms when rocks in the upper mantle melt...Andesitic Magma is found along continental margins....Rhyolitic Magma forms when molten material rises and mixes with the overlying silica-and water-richcontinental crust...All 3 of them is a magma.

What forms when cold water mixes with hot volcanic magma?
This depends on the amount of water and magma, their location, and speed of contact. Magma that cools slowly within a magma chamber usually ends up forming bodies of plutonic rocks such as gabbro, diorite and granite, depending upon the composition of the magma. Alternatively, if the magma is erupted it forms volcanic rocks such as basalt, andesite and rhyolite. The water boils quickly to become steam.
