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.
These are vents through which volcanic gases and water vapour escape to the earth's surfaec.Fumaroles are formed when magma heats underground water,it mixes with volcanic gases and the mixture is eventually released as steam.
When Hydrogen mixes with Oxygen it forms water!!
a crater lake forms
Ester
The more gases, water vapor and silica there is in magma the bigger the explosiveness of a volcanic eruption.
sodium comes out of rocks and mixes in with the water
No, a lahar is not an example of a pluton. A lahar is a volcanic mudflow that occurs when volcanic debris mixes with water, flowing down the slopes of a volcano. A pluton, on the other hand, is an igneous intrusion formed underground by the solidification of magma.
Hot springs and Geysers. A geyser is a foundation of water and steam that erupts from the ground. A hot spring forms when groundwater heated by a nearby body of magma rises to the surface and collects in a natural pool.
Often these are esters. One such is isoamyl acetate. Please see the link.
Yes obsidian is glassy because it cooled very fast.
In volcanic areas, groundwater heated by magma can be a source of hot springs, geothermal energy, and steam. This heated groundwater can also contribute to the formation of hydrothermal features such as geysers and fumaroles.
yes and no. water effects the magma. a lot of water will make magma harden faster. but a little water makes the magma speed up/move faster. magma gases don't really effect water, its really the volcanic ash and toxic fumes that effect the water. (volcanic mudslides also effect water)
