different types of lava fragments
Stromboli has eruptions of different types which are explosions, quiet eruptions, and showers of lava
Different types of lava: A'a Pahoehoe Pillow Lava
the two types of volcanic eruptions are magma and lava
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.
Lava and Tephra (rock, ash, etc.)
higher silica, sio % creates a thicker lava, lower silica sio% creates a thinner, more runny lava viscosity and resistance
there are 4 different types of lava flows maybe more
It is not. Hawaiian lava is basaltic, which is the most common type of lava.
Discounting oceanic crust
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 answer is LAVA the answer is LAVA
Volcanic eruptions are always caused by magma. This applies if the eruption is quiet or explosive, or whether the magma is felsic or mafic.
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
How explosive the lava is depends on the density of the lava. Different types of lava have different densities.
Earth quakes are completely different to volcanic eruptions. Volcanos erupt because of the lava is pushing up.
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.
A volcano grows as a result of eruptions, which add fresh ash or lava to the surface of the volcano.
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.
quiet eruptions (runny lava)
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
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 6 different types of lava. There is Aa, Pahoehoe, Pyroclastic, Andesitic, Rhyolitic, and lastly Basaltic.
Why do Alaska valcano's not lava flows when eruptions happen?
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 * Usually not very tall in height due to gentle slopes Acid-lava Volcanoes * Small base area * Steep slope * Contains acidic lava * Violent eruptions * Creates crater lakes (caldera) after eruptions * Tall in height due to steep slopes Cinder Cones * Small base area * Steep slopes * Symmetrical slopes * Moderate eruptions * Not tall in height as slopes are easily eroded
