Aa is slower, cooler, and has less sillica than pahoehoe. Pahoehoe is faster and moves quickly, and phoehoe has more silica, and is also darker than 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.
What is the difference between pahoehoe and lava?
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.
Are pahoehoe and AA produced during explosive eruptions?
Pahoehoe comes from an explosive eruption, whereas AA comes from quiet eruptions.
Name the two types of lava?
Blocky Lava, Pahoehoe Lava, Aa Lava, Pillow Lava
Does Mount St Helens spew pahoehoe pillow Aa or Blocky lava?
Mount St Helens produces blocky lava.
What is the difference between pahoehoe and AA lava?
The difference between Pahoehoe lava and AA lava is that pahoehoe lava is smooth and AA lava is jagged.
What are the differences between pahoehoe and AA What kind of eruption produces these type 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.

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.

Pahoehoe comes from an explosive eruption, whereas AA comes from quiet eruptions.
What is the difference between a pahoehoe and AA?
Pahoehoe is so much more smoother and duller than AA, because it travels down a gentler slope. You can drive over Pahoehoe. AA, travels down a much steeper slope, and stumbles over itself, and when it hardens, it becomes VERY SHARP AND RAGGED. You wouldn't even be able to walk on AA lava without seriously messing up your feet.
What is the different between aa and pahoehoe?
+Pahoehoe is basaltic lava forming smooth undulating(moving with a smooth wavelike motion) or ropy masses.It is contrasted to AAAA is basaltic lava forming very rough jagged masses with sharp projections and a light frothy texture. Pahoehoe+Both are types of lava. Aa is sharp (so you say Aaah as you walk on it), whereas pahoehoe is smooth
Are pahoehoe and AA produced during explosive eruptions?
Pahoehoe comes from an explosive eruption, whereas AA comes from quiet eruptions.
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.
What kinds of eruption produces pahoehoe and 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.
What is a pahoehoe flow?
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 do not stand in either.
