The different types of eruptions that result from different types of lava?
different types of lava fragments
Stromboli has eruptions of different types which are explosions, quiet eruptions, and showers of lava
higher silica, sio % creates a thicker lava, lower silica sio% creates a thinner, more runny lava viscosity and resistance
Pahoehoe and another
Quiet Eruptions produce pahoehoe lava. It also can produce Aa lava. Pahoehoe is a fast moving and a hot lava. Pahoehoe looks like wrinkles once it starts to cool down.
the two types of volcanic eruptions are magma and lava
Different types of lava: A'a Pahoehoe Pillow Lava
It is not. Hawaiian lava is basaltic, which is the most common type of lava.
Caldera-forming eruptions do not involce lava flows but massive plumes of ash and pumice. The material produced is usually rhyolite. After a caldera-forming eruption, however, the composition can shift, especially since eruptions can be triggered by the mixing of different types of magma.
the different types of volcanoes are cinder cones, shield volcanoes and composite volcanoes. Cinder cones form from explosive eruptions. Shield volcanoes are composed of quiet lava flows. volcanoes built up of alternating layers of rock particles and lava are cold composite volcanoes
Lava and Tephra (rock, ash, etc.)
Volcanic eruptions are always caused by magma. This applies if the eruption is quiet or explosive, or whether the magma is felsic or mafic.
Discounting oceanic crust
What are the differences between pahoehoe and Aa what kind of eruption produces these types of lava-?
Pahoehoe is hot, fast-moving lava that has a low viscosity. AA lava has a cooler temperature and moves more slowly. Quiet eruptions are the type that produce these two types of lava.
there are 4 different types of lava flows maybe more
Earth quakes are completely different to volcanic eruptions. Volcanos erupt because of the lava is pushing up.
A volcano grows as a result of eruptions, which add fresh ash or lava to the surface of the volcano.
True. Many eruptions produce massive clouds of ash, gas, and pumice rather than lava. Phreatic eruptions, as another example, are essentially steam explosions.
There are four main types of volcanoes, namely Shield Volcanoes, Composite Volcanoes, Cinder Cones and Acid-lava Volcano. Shield Volcanoes: * Large base area * Gentle slope * Contains basic lava * Frequent eruptions * Quiet and gentle eruptions * Very tall in height due to large base area Composite Volcanoes: * Relatively small base area * Concave slope * Contains acidic lava * Violent eruptions * Repeated eruptions * Erupts from the side cones *… Read More
How explosive the lava is depends on the density of the lava. Different types of lava have different densities.
the answer is LAVA the answer is LAVA
Why are scientists able to use rocks to be able to find out that a volcano is explosive or nonexplosive?
Explosive and non-explosive eruptions form different types of rock. Explosive eruptions tend to have fragmented rocks composed of cinders, ash, and pumice. Non-explosive eruptions usually produce lava flows, which tend to cool as solid sheets or channels of rock.
Mt. St. Helens has had several different styles of eruptions through its history. The types of eruptions vary from explosive to dome building. The explosive history of Mt. St. Helens is relatively well known from the May 18, 1980 eruption that captured world attention at the time. The eruption style was typical of this volcano, pyroclastic flows and lahars were both generated. The flank collapse was more than likely a result of the earthquake under… Read More
A'a Pahoehoe Pillow Lava The difference between the lava is the elements and amount of water inside the volcano. Also, the thickness of the lava.There are 4 different types of lava flows maybe more
The viscosity of magma or lava will determine whether or not the eruption is explosive or quiet. Higher viscosity magma can result in explosive eruptions. Lower viscosity magmas tend to flow more freely.
The eruptions turn into pillow lava. Pillow lava forms when lava erupts underwater. The lava forms round lumps that are in the shape of pillows.
Igneous rock that flowed out of the surface if lava; lava blown out of explosive eruptions is Volcanic Ash, or Tuff.
The least violent type of volcanic eruption would be Strombolian eruptions. Although the lava is sometimes thrown high into the air, the eruptions are usually short lived.
There are 6 different types of lava. There is Aa, Pahoehoe, Pyroclastic, Andesitic, Rhyolitic, and lastly Basaltic.
quiet eruptions (runny lava)
In one sense, you can divide volcanic eruptions into two general types: "red" eruptions and "gray" eruptions. "Red" eruptions are generally nonexplosive or mildly explosive. These eruptions produce flows or fountains of glowing red lava. The lava flows can be destructive, but they generally move slowly, so "red" eruptions rarely cause a significant loss of life. "Gray" eruptions ares explosive. They produce clouds of hot ash and rock. Some of these clouds race down the… Read More

What ate the differences between pahoehoe and Aa what kind of eruption produces these types of lava?
Pahoehoe and AA lava are produced by quiet eruptions. This means that instead of a blast or explosion, the lava just flows out of the volcano. Pahoehoe lava is hot and flows quickly. AA lava is cooler in temperature and doesn't flow as quickly.
in quiet eruptions, the magma or lava contains more silica than explosive eruptions. in explosive eruptions magma has less silica because lava becomes less dense and can shoot out of an volcano
Lunar maria are areas on the moon where volcanic lava has flowed in the past. It is surmised that they result from asteroid or meteor strikes followed by volcanic eruptions.
No. A "quiet" eruption will produce lava flows. Pyroclastic flows generally result from explosive eruptions.
Because shield volcanoes have lava flows rather than explosive eruptions, they are much quieter than other types of volcanoes. Regardless, shield volcanoes are among some of the largest in the world.
There are several ways to determine what type of eruption a volcano will have. However, the answer is not very straight forward. Although different types of volcanoes are known for different types of eruptions, they can produce other types of eruptions that they are not typically known for. For example, Hawaiian volcanoes, although known for their flowing lava and fire fountains have in recent years been discovered to have very explosive eruptions as well. Another… Read More
Shield volcanoes produce fast flowing lava. They erupt frequently, but eruptions are gentle because the lava is so thin and does not trap gas in the volcano.
Different types of lava have different chemical compositions. Since not all rocks have the same chemical composition and lava is just liquid rock, it does not have an official formula. Most rocks (and therefore lava) are made up of a combination of the elements Oxygen, Silicon, Aluminum, Iron, Calcium, Sodium, Potassium, and Magnesium. Different types of rocks (and lava) have different amounts of these elements. Therefore, there is not a specific chemical formula for lava.
Why do Alaska valcano's not lava flows when eruptions happen?
Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface. At the surface it erupts to form lava flows and ash deposits. Ash deposits result from more explosive activity and lava flows usually are associated with quieter activity. Anyway, once you have piled up lava and/or ash around the vent, you have a young volcano. After many many more eruptions you have a big volcano that is constructed… Read More
they are all different types of volcanoes. A shield volcano generally erupts low viscosity lava with a low silica content. Eruptions are generally not explosive. Such volcanoes are characterized by broad, gentle slopes. A composite volcano or stratovolcano is composed of layers of ash and lava flows. Such volcanoes tend to erupt higher viscosity material with a higher silica content. Eruptions are often explosive, producing plumes of ash, gas, and pumice instead of lava flows… Read More
The type of volcanoes that forms depends on the type of lava its made from . In some places lava is thin and runny, is also thick and stiff .Because there different types of volcanoes.
The effects vary depending on the kind of eruption. In an effusive eruption lava essentially oozes out of a vent or fissure. The lava, which is generally runny, basaltic lava then flows downhill. Such eruptions mean the magma has a low gas content Lava flows of more viscous lavas can occur as well. These flows do not look like the typical lava flow. Then there are various types of explosive eruptions. Fire fountain eruptions are… Read More
