Lava that hardens into rough , jagged rocks with a crumbly feeling aka blocky lava
Thick.
nope. Mt. fuji has pohoehoe for lava i think
Aa is a term for a blocky type of lava.
Generally yes. A'a and pahoehoe are both varieties of basaltic lava, which usually erupts fairly quietly.
AAA is nothing in relation to volcanoes. A'a is a variety of volcanic rock, formed from a basaltic lava flow with a jagged surface.
Neither. Krakatoa mostly produces ash and pumice rather than lava flows. Those lava flows that do occur are block lava flows, indicating material more viscous than a'a or pahoehoe.
No. Pinatubo tends to produce ash and pumice rather than lava flows. A'a is a textural variety of basaltic lava. Pinatubo in recent history has erupted dacitic material, which is far more viscous.
I can't say exactly how much silica a'a has but it generally has a low silica content. Does this help
Kilauea produced both pahoehoe and a'a. These terms refer to the texture that a basaltic lava flow can take on and do not mean a difference in composition. Ofteb Kilauea's lava starts out as pahoehoe and becomes a'a as it cools an becomes more viscous.
AAa
Cerro Azul produces pahoehoe lava. This type of lava is a kind of basiltic lava. It flows quickly and is very fluidy. Coming from Galapagos Island in Ecuador, Cerro Azul is a shield volcano. It has erupted eleven main times in history- the latest eruption was in 2008. That's all I got.
