Is basaltic lava runny?
Basaltic magma, which is high in temperature, very low on silica and with low gas content.
This type of magma produces fluid lava with very little explosive activity.
Basic lava, which is non-acidic and very runny.
No layers, as the volcano just consists of lava..
Is felsic lava thick or thin?
Felsic lavas are not as hot, high in silica and volatiles, and have a high viscosity. They are thick and gooey and resist flowing. Their high volatile content makes them potentially highly explosive.
What is a basaltic lava flow?
Basaltic lava, or mafic lava, is molten rock enriched in iron and magnesium and depleted in silica. … When on land, basaltic lavas are commonly seen as pahoehoe or ‘a’a flows. Underwater, basaltic lavas are erupted as pillow basalts. More rare basaltic lava features include lava lakes and lava fountains.
What is blue lava?
Indonesia’s Kawah Ijen volcano spews out blue lava thanks to its incredibly high levels of sulfur. … It is one of the world’s most unusual volcanoes because instead of producing the usual red lava and black smoke, its underground activities result in bright blue flames rising into the air.
Is Lava wet or dry?
If we’re using it as an adjective (definition: covered or saturated with water or another liquid), then lava is a liquid state so it therefore it’s wet. But nothing touched by lava is left damp or moist, which means that you can’t really use wet as a verb to describe lava.
Can lava melt a diamond?
So, it is impossible for lava to melt a diamond. But the twist is that at atmospheric pressure, it is almost impossible to melt diamond as its burning point is 900 °C (1173 K). So, if the temperature of lava is above this, the diamond will burn (not melt).
Can lava melt bones?
Bone and teeth are complex mixtures of moderately complex components, but some decomposition products may dissolve in magma, but they still won’t melt.
How far can lava flows go?
Viscous andesite flows move only a few kilometers per hour (couple feet per second) and rarely extend more than 8 km (5 mi) from their vents. Viscous dacite and rhyolite flows often form steep-sided mounds called lava domes over an erupting vent.
Can a drop of lava kill you?
Lava won’t kill you if it briefly touches you. You would get a nasty burn, but unless you fell in and couldn’t get out, you wouldn’t die. … Fortunately in both instances the lava was not very deep and they were able to get out quickly.
What would lava taste like?
Mostly once cooled all volcanic rocks have a non taste. … Freshly cooled lava can have smell and taste from roasted trees and other organics that it burned up. Consider that Hawaiian lava cooled in the ocean might taste salty unless the salt was washed away with rain water.
Can lava melt metal?
Liquid lava temperature is not very high, and won’t melt a chunk of steel for example. Consider this – your normal large firewood burns at 600-800 degrees, which is just a little bit less than liquid lava temperature. You can melt lead, aluminium and maybe copper in this (with due insulation), but that’s about it.
Which type of lava is more viscous?
Thus, basaltic magmas tend to be fairly fluid (low viscosity), but their viscosity is still 10,000 to 100,0000 times more viscous than water. Rhyolitic magmas tend to have even higher viscosity, ranging between 1 million and 100 million times more viscous than water.
Is lava hotter than fire?
In fact, as it spills out onto Earth’s surface as lava, the runny rock’s temperature is only a little lower than the hottest part of a candle flame: about 1200 °C. On the other hand, a big blob of lava contains many more bouncing particles than a small candle flame, so it has a lot more heat energy.
Can you drink lava?
You actually can drink lava. The problem is, you can only do it once. you’d burn your lips off before it goes down into your system. In the same sense that shoving chopsticks up your nose into your brain is “smelling” them, I guess pouring molten rock into your torso through your mouth is “drinking” it.
How fast can lava flow?
In general, lava flows slowly (0.25 mph), with maximum speeds between 6–30 mph on steep slopes. An exceptional speed of 20–60 mph was recorded following the collapse of a lava lake at Mount Nyiragongo.
