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
Pahoehoe is a Hawaiian term used to describe smooth, ropy lava flows, while lava is molten rock that erupts onto the Earth's surface. Pahoehoe lava flows tend to be less viscous and flow more easily compared to other types of lava.
Pahoehoe is hotter than other lavas. It is basaltic lava, which is hotter than the other compositional varieties found on earth today. It is also generally hotter than a'a, another common variety of basaltic 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.
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.

Pahoehoe is smooth and rope-like lava that flows easily, while AA is rough, jagged lava that is cooler and slower-moving. Pahoehoe tends to form in low-viscosity lava flows, while AA forms in higher-viscosity lava flows.

Shield volcanoes have low viscosity basaltic lava, which typically creates pahoehoe and AA lava flows due to their ability to flow easily. Composite volcanoes have higher viscosity lava, such as andesitic or dacitic, which tend to form thicker and blockier lava flows rather than pahoehoe and AA flows.

The lava of Krakatoa volcano is typically AAA lava, which is characterized by its thick and viscous texture. This type of lava tends to flow slowly and can create steep-sided volcanoes. Pahoehoe lava, on the other hand, is more fluid and forms smooth, rope-like textures when it cools.
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.
No, pahoehoe lava is not considered pyroclastic debris. Pahoehoe is a type of basaltic lava that has a smooth, rope-like texture due to its low viscosity. Pyroclastic debris refers to fragmented material such as ash, volcanic rocks, and gases that are blasted out of a volcano during an explosive eruption.
Lava flows of pahoehoe and aa indicate that the eruption was effusive ("quiet") rather than explosive, or only very mildly explosive.
