What kind of lava is AA?
A'a is one of two types of flow of basaltic (mafic) lava. A'a is the more viscous of the two and is usually somewhat cooler than the other variety, pahoehoe. A'a forms a surface of jagged rock fragments as it flows.
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.
Thick lava is called aa which is like a paste kind of
It is called aa
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.
The difference between Pahoehoe lava and AA lava is that pahoehoe lava is smooth and AA lava is jagged.
A low amount of silica will create a runny kind of lava found in shield volcanoes. That kind of lava is called Pahoehoe. A high amount of silica will make a thick kind of lava that is found in cinder cone volcanoes. That kind of lava is called Aa.
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.

What is the difference between pahoehoe and AA and what kind of eruption produces these types of lava?
It make a quiet eruption produce two different types of lava-hot, fast-moving pahoehoe and cooler, slower-moving aa.
Aa lava is a basaltic lava with a flow characterized by rough surfaces of clinker.
It has 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.
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.
Lava that is cooler and slower-moving is called aa.
Blocky Lava, Pahoehoe Lava, Aa Lava, Pillow Lava
Pahoehoe lava, Aa lava, and Blocky lava
It had high silica lava, or AA lava.
1) Pahoehoe 2) Aa Pahoehoe is lava which move fast and is slipery. Aa is lava which moves slowy and is very sticky.
aa is produced by quiet eruptions
No. A lava flow usually indicates an eruption that is not explosive.
AA: jagged chunks of lava formed by rapid cooling on the surface of a lava flow
The four types are block lava Pahoehoe lava Aa lava and pillow 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
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.
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.
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 .
that lava is called ''aa''
no. AA has a relatively low silica content level.
Eather AA, pahoeheo, Pillow lava, or blocky lava. That is what I know
Aa is the name of hard, or rough lava. Unlike pahoehoe, which is a smooth water like lava.
The two types of lava are aa and pÄhoehoe.
Aa lava is the type of lava that forms a thick, brittle crust.
pahoehoe and aa
No it is 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
-Pillow -AA lava -Pa hoe hoe -Fire hose
"Aa" lava is the rough sort made from cinders.
Fast moving lava is called "Pahoehoe" And slow moving lava is called "aa" .
Pahoehoe lava is highly liquid and cools with a smooth, ropey surface. Aa is made of more viscous lava and usually has a rough, blocky texture.
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.
Aa is a type of lava that hardens into rough chunks and is cooler than Pahoehoe. It moves slow.
its called "aa''
Aa and pahoehoe are both produced from basalt lava eruptions. The difference in the two being a difference in temperature. Pahoehoe is a hotter flow, moving more smoothly before cooling into rope-like structures. Aa is a bit cooler, forming solid chunks, but continuing to move.
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.
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
pahoehoe is smooth and rope like sufaces. Aa is sharp and jaged last pillow lava is pressure billds up in side the lava untill it craks then it pours out forming yet another pillow on the last one.
