Lava tubes are usually produces by pahoehoe.
Lava tubes are characteristic of pahoehoe, as it can maintain a solid crust. With a'a the crust on the flows is constantly breaking.
Pahoehoe
The difference between Pahoehoe lava and AA lava is that pahoehoe lava is smooth and AA lava is jagged.
The lava is pahoehoe Lava.
Pahoehoe is fast-moving,hot lava that has low viscosity.
Not necessarily. All pahoehoe is basaltic, but not all basaltic lava is pahoehoe. A'a and scoria are also basaltic.
Both pillow lava and pahoehoe lava have about the same composition and harden into a kind of rock called basalt.
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.
Pahoehoe is a type of basaltic lava flow. The kind of eruption that causes pahoehoe is a quiet volcanic eruption.
all lava
Pahoehoe lava, Aa lava, and Blocky lava
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.
