Does a composite volcano have an Aa type of lava?
A'a can occur at composite volcanoes, but block lava flows, which are far more viscous, are more common.
A Stratovolcano Composite Volcano with aa lava
Either a type of lava called AA (ah-ah) comes out of the volcano of a type of lava called pahoho comes out. An Extrusive Igneous Rock.
Why is it that pahoehoe and AA lava are more frequent in shield volcanoes than in composite volcanoes?
Aa and pahoehoe lavas are both basaltic in composition. The lava from composite volcanoes is likely to be granitic.
Lava that is cooler and slower-moving is called aa.
No. If a'a is present it will usually be only a minor portion of the volcano. A'a and pahoehoe are low-viscosity lavas with a low silica content They are usually found in shield volcanoes. A composite volcano is usually primarily composed of composed of tepha (loose ash, pumice, and lapilli), tuff (welded ash), and block lava (very viscous lava flows). This material is usually more viscous with more silica than what goes into a'a and… Read More
It had high silica lava, or AA lava.
this volcano is composed of aa lava because that is the sound people say when they walk on it
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.
Viscious, Obstructive, Lava, Caldera, AA, Neck Thank You!!
Aa lava is the type of lava that forms a thick, brittle crust.
No it is slow
A'a is not a kind of volcano. A'a is a texture that a lava flow can take on, characterized by a surface covered in sharp fragments. There is no particular height to the lava flow, or height of volcano from which such a flow erupts.
its called "aa''
The two types of lava are aa and pÄhoehoe.
Eather AA, pahoeheo, Pillow lava, or blocky lava. That is what I know
The difference between Pahoehoe lava and AA lava is that pahoehoe lava is smooth and AA lava is jagged.
No, generally not. Most composite volcanoes erupt more viscous, high-silica material than what would form a'a. So block lava would be more common.
Aa is a type of lava that hardens into rough chunks and is cooler than Pahoehoe. It moves slow.
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
Aa is a term for a blocky type of lava.
Aa lava is a basaltic lava with a flow characterized by rough surfaces of clinker.
the correct answer would be Aa
It has Aa lava
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
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.
It has aa lava flow and no pyroclastic flows at the moment.
Pahoehoe is faster moving lava and AA is slower moving lava. Both types are found in basaltic type eruptions. They have different appearances. Pahoehoe is smooth and ropey where as AA is chunky and rough.(much like top of trees) Often a pahoehoe flow can change to an AA flow depending upon the type of slope it encounters. The steeper the slope the more likely AA lava will be present. Aa has more viscosity than Pahoehoe.
Blocky Lava, Pahoehoe Lava, Aa Lava, Pillow Lava
That depends on the chemistry of magma the volcano erupts - Basalt, andesite, rhyolite etc. but Generically the rock coming out of a volcano is called lava rock (pahoehoe or aa) but one can also get pumice or ignimbrites.
it hurts to walk on both, and they are both lava. Aa is a rough jagged surface, while I have no idea about blocky lava.
A'a can come from almost any volcano. It is most often associated with shield volcanoes, however.
Pahoehoe lava, Aa lava, and Blocky lava
What do lava flows made of pahoehoe and AA indicate about the type of volcanic eruption that occurred?
Lava flows of pahoehoe and aa indicate that the eruption was effusive ("quiet") rather than explosive, or only very mildly explosive.
AA lava flows look like broken glass and make you say "Ow Ow" when you walk across it barefoot. Pahoehoe lava flows look like pillows.
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.
aa is produced by quiet eruptions
No. A lava flow usually indicates an eruption that is not explosive.
1) Pahoehoe 2) Aa Pahoehoe is lava which move fast and is slipery. Aa is lava which moves slowy and is very sticky.
The four types are block lava Pahoehoe lava Aa lava and pillow lava
AA: jagged chunks of lava formed by rapid cooling on the surface of a lava flow
An explosive eruption includes Aa lava, the volcano has a thick cap which traps all the gasses, this builds pressure. The lava is high in Silica and has lots of water vapor. A non explosive volcano includes, Pahoehoe lava, has a thin cap which lets pressure go easier, and is low in Silica and water vapor.
It is a lava flow, and has an AA (ah-ah) lava flow
aa (ah-ah) lava flows are super jagged in texture and can be called blocky. There are also block flows that are not as jagged but similar to aa. i think the answer is aa.
that lava is called ''aa''
What do lava flow made of pahoehoe and AA indicate about the type of volcanic eruptions that occured?
It was a quiet eruption and it was low in silica
no. AA has a relatively low silica content level.
What are the differences between pahoehoe and AA What kind of eruption produces these types of lava?
The differences are that Pahoehoe produces fast moving lava; Aa produces slower moving lava. The kind of eruption that produces these types of lava is a quiet eruption.
