What happens when basaltic lava reaches the ocean?
When lava comes into contact with ocean water it produces a gas plume known as laze – lava and haze. Laze forms through a series of chemical reactions as hot lava boils the colder sea water.
What is it called when lava meets the ocean?
The ocean entry is producing a laze plume. Laze is formed when hot lava hits the ocean sending hydrochloric acid and steam with fine glass particles into the air. Health hazards of laze include lung damage, and eye and skin irritation. Be aware that the laze plume travels with the wind and can …
What happens when lava hits water?
When the large surface of lava hits deeper water, Volcano Watch says the result can be flash steam that can lead to explosions of varying magnitudes. The explosions can cause fragments of molten rock and volcanic glass, created when the lava rapidly cools, to be launched into the air.
What does basaltic lava produce?
Basaltic lava fountains and fissure eruptions, however, still form explosive fountains hundreds of meters tall. Common minerals in basalt include olivine, pyroxene, and plagioclase.
What happens once basaltic magma is formed?
Basaltic magma is usually very dense and gets stopped in the continental crust rather than reaching the surface, causing it to crystallize. This crystallization releases the basaltic magma's heat, causing the temperature of the continental crust to rise and melt.
What is basaltic lava?
Basaltic lava is another term for mafic lava. Mafic lava is molten rock that is enriched in iron and magnesium and low in silica. When mafic lava cools on the earth's surface, it forms basalt, which is why mafic lava is commonly called 'basaltic lava.
When lava mixed with water is formed?
Hydrovolcanism: When Magma and Water Mix.
Does lava turn water into acid?
Yes. Crater lakes atop volcanoes are typically the most acid, with pH values as low as 0.1 (very strong acid). Normal lake waters, in contrast, have relatively neutral pH values near 7.0.
What happens to water as it interacts with hot magma?
Magma rising through the Earth's crust carries with it a great deal of heat, or thermal energy. If this hot magma comes in contact with water (or ice), either on the surface or in the subsurface, the water can be quickly converted to the gaseous state (steam) via the transfer of thermal energy.
What is basaltic lava flow?
Basalt is a hard, black volcanic rock with less than about 52 weight percent silica (SiO2). Because of basalt's low silica content, it has a low viscosity (resistance to flow). Therefore, basaltic lava can flow quickly and easily move >20 km from a vent.
What do magma forms on the ocean?
When located beneath the ocean, these plumes, also known as hot spots, push magma onto the seafloor. These volcanic mounds can grow into volcanic islands over millions of years of activity. Transfer of HeatMagma can also be created when hot, liquid rock intrudes into Earth's cold crust.
Where are basaltic lava flows?
Basaltic lava flows on Earth are erupted on the mid-ocean ridge system, magmatic arcs, ocean islands, and flood basalt terranes in LIPs. The dark lunar mare are plains of basaltic rock formed by impact melting. Lunar lava flow produced by shock melting.
What happens when water interacts with magma?
The major effect of magma–water interaction is an increase in thermal energy flux and induction of a special type of magma fragmentation, i.e., phreatomagmatic fragmentation.

When lava mix with water is called?
Hydrovolcanism: When Magma and Water Mix.
What magma is called when it reaches the surface?
When magma reaches Earth's surface and erupts from a volcano, it becomes lava.
What is a basaltic flow?
Basalt flows are noneruptive, voluminous, and characterized by relatively low viscosity. They generally advance less than one mile or kilometer per hour on gentle slopes and may reach more than 30 mi (50 km) from their source or erupting vent.
How does the heat in the magma affect the water?
The large thermal gradients near the magma–water contact will produce large pressure and velocity gradients, and perturba- tions in water movement may result in hydro- dynamic instability.
What does lava turn into?
Lava cools to form volcanic rock as well as volcanic glass. Magma can also extrude into Earth's atmosphere as part of a violent volcanic explosion. This magma solidifies in the air to form volcanic rock called tephra. In the atmosphere, tephra is more often called volcanic ash.
Can you drink lava?
Wax, kerosene, and polyethylene glycol are found, all dissolved in water. Wax is, in general, non-toxic in humans. Kerosene, at least in the amount that could be found in a lava lamp, is not poisonous, but the polyethylene glycol, could be a problem.
What happens when magma reaches the surface?
When magma reaches Earth's surface and erupts from a volcano, it becomes lava.
Which type of volcano ejects a basaltic magma?
Shield volcanoes Shield volcanoes They are built up slowly by the accretion of thousands of highly fluid lava flows called basalt lava that spread widely over great distances, and then cool as thin, gently dipping sheets. Lavas also commonly erupt from vents along fractures (rift zones) that develop on the flanks of the cone.
How does water interact with lava?
Water has a greater opportunity to penetrate into the cracks of a'a, where it expands explosively and fragments the lava into airborne particles. Littoral cones can develop at the water's edge from the accumulation of these airborne fragments.

Can you pee in lava?
While exploring an active volcano, Dante Lopardo decided to urinate on some molten rock, which has a temperature of about 700°C. As seen in the video Lopardo took, the pee instantly vaporizes as it hits the liquid rock and the lava sizzles. It also leaves something of a charred black mark after sizzling off.
What’s lava taste like?
Hot volcano lava would instantly burn away your taste buds so the taste would not be discernible.
What is formed when magma reaches the top of the volcano during an eruption?
Magma can also extrude into Earth's atmosphere as part of a violent volcanic explosion. This magma solidifies in the air to form volcanic rock called tephra. In the atmosphere, tephra is more often called volcanic ash. As it falls to Earth, tephra includes rocks such as pumice.
What do you call the heated magma which reaches the Earth’s surface?
Magma is molten rock material. As magma cools the elements within the magma combine and crystalize into minerals that form an igneous rock. Magma cools either below the surface or at the surface (magma that reaches the surface is called lava).
Which type of volcano Release thick or viscous lava that can reach great heights?
In fact, Mount Vesuvius is a composite volcano that is most famous for burying the ancient Roman city of Pompeii in up to 20 feet of volcanic ash in 79 AD. The explosiveness of their eruptions is due to the thick, highly viscous lava that is produced by composite cone volcanoes.
When a volcano ejects lava explosively The eruption is called?
A Pelean eruption is associated with explosive outbursts that generate pyroclastic flows, dense mixtures of hot volcanic fragments and gas described in the section Lava, gas, and other hazards. Pelean eruptions are named for the destructive eruption of Mount Pelée on the Caribbean island of Martinique in 1902.
