Would a'a form lava tubes or pahoehoe?
Lava tubes are characteristic of pahoehoe, as it can maintain a solid crust. With a'a the crust on the flows is constantly breaking.
Lava tubes are usually produces by pahoehoe.
Lava tubs form as a result of pahoehoe lava flows. As one of these flows progresses, it builds of a layer of rock on top of it. eventually, thus becomes thick enough to support is own weight, and forms an insulating tube through which lava can flow.
Neither. A'a and pahoehoe are lava flows that occur when basaltic lava is erupted in a non-explosive fashion. Vesuvius erupts exolisvely, producing clouds of ash and pumice rather than lava flows, and the material is of a different composition from the lava that forms a'a and pahoehoe. If it were to come out as lava, it would form a block lava flow.
No. Lava tubes generally form with basaltic lava. The rhyolitic lava that the Yellowstone volcano would produce is to viscous.
Pahoehoe lava forms by small pieces of lava from an irregular flow. It is typical in certain types of volcanoes such as shield volcanoes.
there is no difference between pahoehoe and lava because pahoehoe is a type of lava there is a difference between pahoehoe lava and AA (ahah) lava
Not always. Shield volcanoes produce basaltic lava, which can form into either pahoehoe or a'a. Sometimes both are found in the same lava flow.
The lava is pahoehoe Lava.
A pahoehoe is a form of lava flow of basaltic rock, usually dark with a smooth or ropey surface.
The difference between Pahoehoe lava and AA lava is that pahoehoe lava is smooth and AA lava is jagged.
basaltic lava can form a'a, pahoehoe, or pillow lava.
Niether. Pahoehoe and a'a are terms that apply to lava with a mafic composition (low silica content, low viscosity). Tambora's massive 1815 eruption would have produced ash and pumice, but not lava flows. An eruption as explosive as that usually indicates felsic material (high silica content, very high viscosity), which will form block lava rather than a'a or pahoehoe.
Yes. Pahoehoe is a variety of basaltic lava.
Pahoehoe or pillow lava - same thing
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.
Pahoehoe is a texture that is found in highly fluid lava. It occurs due to the deformation of the flow of the lava. A pahoehoe rock is the result of the cooled lava.
Neither. There are more kinds of lava than a'a and pahoehoe. Both of these are texture varieties of mafic lava, which cools to form basalt. Mount Rainier erupts lava of a different composition of an intermediate composition, which contains more silica than mafic lava and forms andesite when it cools. This lava is far more viscous than a'a or pahoehoe.
The types of lava flows that are found on the moon are lava tubes, block lava, aa lava and pahoehoe lava. The youngest lava found on the moon is about 2000 years old, while the oldest lava flow is about 15,000 years old.
Pahoehoe and a'a have essentially the same composition. They both cool to form a kind of rock called basalt.
it is called pahoehoe
Its called pahoehoe
Pahoehoe lava is a lava type flowing from volcanic eruptions. It is not to be confused with Aa lava. Pahoehoe is smooth and ropy lava, cooling into a ropy texture. Aa, on the other hand, is stony and rough. On another note (take this as you will): I would rather stand on Aa lava because it is cooler, characterised simply by its viscosity. Pahoehoe is at around 1100-12000C, as opposed to 1000-1100 for Aa. Please… Read More
Not necessarily. All pahoehoe is basaltic, but not all basaltic lava is pahoehoe. A'a and scoria are also basaltic.
What do lava flows made of pahoehoe and Aa indicate about the type if volcanic eruption that occurred?
The lava structures of a'a and pahoehoe indicate the viscosity (resistance to flow) and temperature of the lava as it was erupting. The pahoehoe structures form when the lava is more fluid and hotter and a thin crust is able to congeal before deformation by the heat of the interior of the flow. The a'a structures form when the lava is slightly cooler and less fluid as it travels downslope. A pahoehoe-forming lava can cool… Read More
Both pillow lava and pahoehoe lava have about the same composition and harden into a kind of rock called basalt.
The differences between pahoehoe and AA lava pahoehoe is fat moving lava and looks like wrinkles curves but smother than AA.Aa is cooler than pahohoe and is all bumpy .
A rope shaped or billowy shaped flow is a form of basaltic lava known as Pahoehoe.
Pahoehoe lava wrinkles as the lava moves underneath while pillow lava forms rounded lumps like pillows it erupts underwater
Yes. Pahoehoe is lava, specifically basaltic lava which ranges from 1,800 to 2,200 degrees Fahrenheit.
Pahoehoe and a'a are textural variaties of basaltic lava, which has a low viscosity, meaning it flows fairly easily. This is the reason for the gentle slopes of shield volcanoes.
Blocky Lava, Pahoehoe Lava, Aa Lava, Pillow Lava
pahoehoe or a'a rocks are the most common coming from a lava flow. pahoehoe or a'a rocks are the most common coming from a lava flow. pahoehoe or a'a rocks are the most common coming from a lava flow.
When Mauna Loa erupted in1984 a river of lava flowed from its summit Most of the material that came from that eruption would be what?
pahoehoe lava, aa lava
thr pic ubove is not pahoehoe pahoehoe is grey [PAH hoye hoye]
ropey lava = Pāhoehoe
1) Pahoehoe 2) Aa Pahoehoe is lava which move fast and is slipery. Aa is lava which moves slowy and is very sticky.
Pahoehoe and a'a refer to different texutres of lava flows. Although cindercones can produce lava flows, their main mode of eruption is called "fire fountaining" which tends to produce chunks of lava called scoria, rather than pahoehoe or a'a.
Pahoehoe lava, Aa lava, and Blocky lava
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.
Pahoehoe isn't used for anything, it is a natural cause. It is a type of lava. Pahoehoe means smooth and unbroken lava, when is cools to rock, it forms a ropey, billowing and smooth texture.
A pahoehoe flow is a type of lava flow in which fluid lava forms a "ropey" texture. The other common type of lava flow is a'a, which has a jagged, broken surface.
Kilauea produced both pahoehoe and a'a. These terms refer to the texture that a basaltic lava flow can take on and do not mean a difference in composition. Ofteb Kilauea's lava starts out as pahoehoe and becomes a'a as it cools an becomes more viscous.
No. Many shield volcanoes produces pahoehoe.
Different types of lava: A'a Pahoehoe Pillow Lava
Niether. Pahoehoe and a'a are both varieties of basaltic lava. The material from Pinatobo is of a dacitic composition, which is much more viscous than a'a or pahoehoe. It tends to erupt explosively, producing ash and pumice rather than lava flows. When dacitic lava does flow it creates a block lava flow.
Unlike limestone caves, which can take thousands of years to form, lava caves and lava tubes form almost instantaneously, as they form from rapid cooling.
This type of lava is Pahoehoe.
The four types are block lava Pahoehoe lava Aa lava and pillow lava
The lava is pahoehoe Lava.
It can be if it takes the form of a type of lava flow called pahoehoe. However, basalt may also come in the form of jagged a'a flows.
