what are the components of lava?

Answer 1

glass and crystals

Glass is volcanic material that froze quickly without forming into anything that you can see.

Crystals are visable mineral grains that cooled from the magma before eruption.

Answer 2

Lava is molten rock expelled by a volcano during an eruption.

In general, a lava's composition determines its behavior more than the temperature of its eruption. Igneous rocks, which form lava flows when erupted, can be classified into three chemical types; felsic, intermediate, and mafic. These classes are primarily chemical; however, the chemistry of a lava also tends to correlate with the magma temperature, its viscosity and its mode of eruption.

Felsic lavas such as rhyolite and dacite are often associated with strombolian eruptions, is high in silica, aluminium, potassium, sodium, and calcium, forming a polymerized liquid rich in feldspar and quartz.

Intermediate or Andesitic lavas are lower in aluminium and silica, and usually somewhat richer in magnesium and iron.

Mafic or basaltic lavas are typified by their high ferromagnesian content. Basaltic magma is high in iron and magnesium, and has relatively lower aluminium and silica.

Ultramafic lavas such as komatiite and highly magnesian magmas which form boninite take the composition and temperatures of eruptions to the extreme. Komatiites contain over 18% magnesium oxide

Answer 3

It depends on what type of lava. Basaltic lavas contain calcium plagioclase feldspars, pyroxenes and olivines. Rhyolitic lavas contain potassium feldspars, sodium plagioclase feldspars, amphiboles, micas and quartz. These are the end points of a whole range of other lavas, which contain a wide variability of mineralogy.

Answer 4

Lava is mostly silica, aluminium, potassium, sodium, calcium, magnesium and iron. Additionaly, it can be classified into three chemical types; felsic, intermediate, and mafic. The chemistry of a lava also tends to correlate with the magmas temperature, its viscosity and its mode of eruption. (lava is called magma while contained within the earths surface)

Felsic lavas erupt at temperatures as low as 650 to 750 and are often associated with lava domes and sheeted flows. They are also associated with pyroclastic surge deposits. They are extremely viscous, due to the high in silica, aluminium, potassium, sodium, and calcium content which forms a polymerized liquid rich in feldspar and quartz, which is much more sticky than other magma types. Felsic magmas can erupt at temperatures as low as 650 to 750 degrees Celsius, although they can be hotter.

Intermediate lavas range from 750 to 950 degrees Celsius and are lower in aluminium and silica, and usually somewhat richer in magnesium and iron. They are also associated with domes and sheeted flows. Poorer in aluminium and silica than felsic lavas, they are less viscous.

Mafic or basaltic lavas are typified by their high ferromagnesian content, and generally erupt at temperatures in excess of 950 degrees Celsius. Basaltic magma is high in iron and magnesium, and has relatively lower aluminium and silica, which taken together reduces the degree of polymerization within the melt. Due to the higher temperatures, viscosities can be relatively low.

Answer 5

Lava leads to the development of Igneous rock rocks such as Granite (as opposed to sedimentary like Sandstone or Slate).

These essentially are made up of Feldspars, quartz, olivines, pyroxenes, amphiboles, and micas. These are essentially the minerals in the formation of igneous rocks. All other minerals present are regarded as nonessential (called accessory minerals).


(I paired this response down but essentially it was taken from Wilkapedia)

Answer 6

lava consists of molten form of many metals like iron and gases like sulphur dioxide

Answer 7

Could be every thing in the core of the earth.

Answer 8

I believe it's molten basaltic rock.
