The colour that it is lol. For a picture go here: http://www.Flickr.com/photos/coreywilloughby/254842207/ Im not sure if it is actually magma or a water splash, but that is what the colour should be.
Magma is called lava when it gets to the top, and the colour it turns when it cools down is white through yellow, orange and red, until it finally becomes a black colour as it hardens and solidifies into rock.
Volcanoes can be black, brown, gray, or reddish depending on the material they erupt.
Magma is white when its inside the volcano but, when it gets out its called lava and it turns red because air hits it just like blood!!! go on another site.. this site sucks!
Magma as it is molten often glows red or orange. Magmas with lower melting points might not clow and may appear black or gray.
brown
brown
mafic
Norris Geyser Basin is the hottest geyser.
No single volcano can claim this. The hottest type of lava, basaltic lava, is also the most common. It erupts at temperatures of 1,800 to 2,200 degrees Fahrenheit.
why is the creater and the magma and the ventard the most important part of a volcano?
Felsic magma tends to be thick and viscous, while mafic magma tends to be fluid.
Composite volcanoes can contain virtually any kind of magma ranging from basaltic to rhyolitic. Andesitic magma is the most common. One stratovolcano contains unique carbonatite magma, which is unlike the magma of any other volcano in the world.
Steaming
The latest and hottest fads is pink hair color. In 2012 it was the platinum hair color which most celebrities used for their concepts. Now pink hair color is inspired from asian manga and anime.
It should be magma is the hottest because it is usually molten rock that has not reached the surface during an eruption.Lava is 2nd hottest. It is the molten rock we see when a crack in the crust of the earth or a volcano eruption allows molten rock from beneath the crust to come up.
Green to black.
One of the most hottest star is Eta carinae. its surface temperature is 36000-40000 Kelvin. it color is blue.
High pressure steaming allows you to cook your food, but saved most of the nutrients in it. Such as steaming broccoli instead of cooking it in water.
magma
wet magma is nothing but magma which is cooling down.if wet magma touches water, it will cool down the magma.2. Much volcanic material, magma included contains water - hence forming clouds above an active volcano. But seldom is material ejected from the throat steaming when it lands, therefore most of the moisture is rapidly dissipated.Volcanic glasses can occasionally contain water, under large pressure and temperature, and upon the explosive ejection, may form pumice or ignimbrite.Presumably the water in the magma was entrained during the subduction phase of the cycle.
i think the hottest is Egypt
copper white
Depends on what it's made of, but most is black. It looks red (or even yellow) from the heat ... but that's just radiation.
The Arabian Desert is the hottest 'A"' desert.
