What are the differences between the pahoehoe and AA?
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
Do cinder cone volcanoes have AA lava or pahoehoe lava?
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.
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 slow moving and hot moving lava called in Hawaiian?
pahoehoe is the more smooth lava flows. a'a is the very jagged, sharp lava.
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.
What do lava flows the 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.

What do lava flows made of pahoehoe and AA indicate about the type of volcanic eruption that occured?
They indicate that an eruption is effusive rather than explosive.

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.
Was the Soufriere Hills an AA or a pahoehoe eruption?
Neither. Pahoehoe and a'a are both basaltic lavas (mafic composition). Soufreier Hills erupts andesitic material (intermediate composition). This material took the form of ash and pumice forming pyroclastic flows (which are more like avalanches) rather than lava flows.
What is the slow moving and hot moving lava called in Hawaiian?
pahoehoe is the more smooth lava flows. a'a is the very jagged, sharp lava.
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.
