The sea is called “dead” because its high salinity prevents macroscopic aquatic organisms, such as fish and aquatic plants, from living in it, though minuscule quantities of bacteria and microbial fungi are present.

In actuality, it is nearly impossible to swim in the Dead Sea. Because of the high salt content of the water, people who bathe in the Dead Sea can actually float on the surface of the water. The unique salt and chemical content of the waters of the Dead Sea make it toxic upon contact to fish and nearly all marine life.

Due to the high salinity of the Dead Sea, many living creatures, including marine animals, are unable to stay alive in the sea. However, there is one organism that can survive this extreme environment, named Haloferax volcanii. Haloferax volcanii is one of the microbes that live in the Dead Sea.

Scientists captured video evidence of sharks living in a volcano. The scientists dropped a camera into the main crater of the volcano Kavachi, located in the Solomon Islands.

If the drop is just like a water droplet, it will give you severe injury, as the temperature of lava is quite high, but not possiblly kill you. But as lava has very high density, a drop it will form will be normally very big and it has a possibility of kill you if you come in contact. So, stay away from lava drop.

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. With prolonged contact, the amount of lava “coverage” and the length of time it was in contact with your skin would be important factors in how severe your injuries would be!

If you tried to eat it, you would suffer burns before you ever got it in your mouth. If it was poured into your open mouth by someone else, it would cause third degree burns. You wouldn’t be able to swallow it — lava is molten rock, and as such, is extraordinarily dense and viscous.

In addition to regular menu items like café latte, cakes and sandwiches you can order edible lava at Bræðraborg Café in the town of Ísafjörður in the Westfjords. The pieces look exactly like lava, and they even feel like lava in your hand, so people don’t believe they are actually edible until they bite into them!”

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. Cool lava is darn close to pottery (ceramics) with hardly any taste.

Dipping your hand into molten rock won’t kill you instantly, but it will give you severe, painful burns — “the kind that destroy nerve endings and boil subcutaneous fat,” says David Damby, a research chemist at the USGS Volcano Science Center, in an email to The Verge. Now, falling into lava is another story.

Most lava is very hot—about 2,000 degrees Fahrenheit. At those temperatures, a human would probably burst into flames and either get extremely serious burns or die. That lava was less than 1,000 degrees Fahrenheit, though, and the person who survived was still recovering and in pain more than five months later.

Unaware of the arterial damage, his powerful heart continued pumping large quantities of blood toward the oxygen-starved muscles in his right leg, causing valuable blood cells to accumulate uselessly in the expanding interstitial space. Without immediate medical intervention, the wound would have killed him.

While your lungs would almost undoubtedly be irrevocably charred from the hot air above the lava (assuming relatively static air conditions over the lava), it takes about 80 seconds for the average human to fall unconscious from lack of oxygen, and I highly doubt your body will last that long.

Soldier survives 70-foot fall into active Hawaiia’s Kilauea volcano. A 32-year-old soldier attempting to get a better view inside of Hawaii’s Kilauea volcano fell in Wednesday night, authorities said. He was seriously injured, but survived after falling 70 feet into the volcano’s crater.

There is no way to stop the flow of lava, scientists say. Many have tried in the past, including famed U.S. Gen. Patton, who attempted to bomb lava in its tracks. According to the U.S. Geological Survey, Patton was a lieutenant colonel in 1935 when another volcanic eruption on Hawaii’s Big Island threatened Hilo.

Fluid basalt flows can extend tens of kilometers from an erupting vent. The leading edges of basalt flows can travel as fast as 10 km/h (6 mph) on steep slopes but they typically advance less than 1 km/h (0.27 m/s or about 1 ft/s) on gentle slopes.

Scientists use the term magma for molten rock that is underground and lava for molten rock that breaks through the Earth’s surface.

Lava pouring into the ocean has created a plume made of fumes from hydrochloric acid, steam and fine particles of glass. When the lava enters the ocean, it generates a laze plume — a dangerous mix of lava and haze that can cause eye, lung and skin irritation.

The temperature of lava flow is usually about 700° to 1,250° Celsius, which is 2,000° Fahrenheit. Deep inside the earth, usually at about 150 kilometers, the temperature is hot enough that some small part of the rocks begins to melt. Once that happens, the magma (molten rock) will rise toward the surface (it floats).

New bathymetric and gravity mapping, refined volume calculations and petrologic analyses show that the Hawaiian volcano Pūhāhonu is the largest and hottest shield volcano on Earth. This ∼12.5-14.1 Ma volcano in the northwest Hawaiian Ridge (NWHR) is twice the size of Mauna Loa volcano (148 ± 29 vs.

So by the time it’s out of the volcano, lava is generally not quite hot enough to melt the rocks it flows over. But lava flows can set fire to grass, bushes and trees. And sometimes if houses are in the way, the lava flow will set fire to the wood that is in the houses. All that is left of the house is ash.

Rocks that cool quickly, especially the outer layers of a flow, are primarily composed of glass particles and tiny mafic minerals. This is why the outer surface of a flow is black. The most abundant felsic mineral in lava rock is plagioclase feldspar, which gives the surfaces a waxy luster.

lava flow. Lava (magma that has erupted onto the Earth’s surface) is visually mesmerizing – as the molten rock flows downhill, lava exposed to the air cools to a deep black color, while the molten rock beneath glows bright orange. When magma flows or erupts onto Earth’s surface, it is called lava.

When geologists refer to magma, they’re talking about molten rock that’s still trapped underground. If this molten rock makes it to the surface and keeps flowing like a liquid, it’s called lava. Magmas vary in their chemical composition, which gives them—and the volcanoes that contain them—different properties.

Some are heavy, some are light. Others are dark, while some can be almost pure white. Even igneous rocks that are all formed from magma in the Earth’s mantle can look very different.
