What forms when magma cools and hardens?
Volcano lava forms as rocks as it cools down. Rocks are formed with magma and lava which when cooled down would form as rough matters. Rare lava parts are formed up like ruby, diamonds, and even emeralds.
What do both silica and water do to magma?
Silica is silicon dioxide. Is is perhaps the most common compound on earth. In magma the amount of silica is key in determining the viscosity. More silica leads to a more viscous magma.
Which property of magma will change the viscosity?
Silica content determines viscosity. The higher the silica content the more viscous (slower moving). Ultramafic <45% silica Least viscous Mafic 45-52% Silica Intermediate 53-65% Silica Felsic >65% Silica Highly viscous
How does the amount of silica content change the viscosity of magma How does this affect the flow of magma?
The amount of silica and water affect the viscosity of the magma. The more viscous the magma, the slower the flow rate and the shorter and the thicker the flows. Silica makes for a more viscous magma.
What igneous rocks are formed from from hardened lava?
It would have to be a volcano rock because the heat and magma hardens it and make it into a igneous rock. So when the volcano explodes it explodes with the magma. So when the magma heats and hardens it transforms into an Igneous rock.
How can bowens reaction series determine the silica content in magma?
Higher silica contents will be in the igneous rocks that form with lower temps. Ones that form earlier in the series like olivine have lower percentages of silica.

How does magma turn to a igneous rock?
magma pushes its way up through cracks and may become trapped surrounded by solid rocks, the magma cools slowly it may take centuries to harden during this long time the igneous rocks form with large crystals large crystals give rocks a coarse texture hope this helps with your homework! i hate science even if I'm kinda good at it!
Do igneous rocks have a coarse texture?
Igneous rocks have different textures for two reasons.The first reason is that the magma from which the igneous rocks were made can be acid (having a lot of silica in it like Granite) or basaltic (having less silica and a lot more dark minerals). The acidity of a magma has a great affect on the viscosity of the lava and this affects the texture of the rocks formed.The second (and more important) reason relates to the speed with which the magma cools. If the magma cools quickly the crystals are small and the rocks are fine textured. If the magma cools slowly the rocks end up with big, course grained crystals.
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 is a dark colored low silica rock?
Mafic igneous rocks, like basalt, are dark colored and low in silica.
What is a dark-colored low silica rock?
Mafic igneous rocks, like basalt, are dark colored and low in silica.
Which feature forms when magma cools beneath Earth’s surface?
igneous rocks When magma cools and solidifies in these spaces, Intrusive or plutonic igneous rocks are formed deep beneath the Earth's surface. Intrusive features like stocks, laccoliths, sills, and dikes are formed.
