No, generally not. Most composite volcanoes erupt more viscous, high-silica material than what would form a'a. So block lava would be more common.

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.


Does a composite volcano have an Aa type of lava?

A'a can occur at composite volcanoes, but block lava flows, which are far more viscous, are more common.


What type of lava forms rough jagged edges?

Block-lavas is considered to be the tougher and thicker form of lava.


What kind of lava does composite volcanoes produce AA or pahoehoe?

Usually neither. A'a and pahoehoe lavas are both of mafic composition (rich in iron and magnesium, poor in silica) and form basalt when they cool. Composite volcanoes usually erupt material of intermediate to felsic composition (felsic is rich in alkalis, aluminum, and silica), with lavas cooling into rocks such as andesite, dacite, and rhyolite.


How did AA lava get its name?

Aa lava is a basaltic lava with a flow characterized by rough surfaces of clinker.


What type of lava does a quiet eruption produce?

they poduce shield volcanoes like the hawiian islands


What kind of lava hardens to form chunks?

It is called aa


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.


Layers of thin runny lava that flow over a wide area before they cool and harden can build up what?

Lava Plateaus


Is a composite volcano made of Aa lava?

No. If a'a is present it will usually be only a minor portion of the volcano. A'a and pahoehoe are low-viscosity lavas with a low silica content They are usually found in shield volcanoes. A composite volcano is usually primarily composed of composed of tepha (loose ash, pumice, and lapilli), tuff (welded ash), and block lava (very viscous lava flows). This material is usually more viscous with more silica than what goes into a'a and pahoehoe.


What are the three types of lava?

Pahoehoe lava, Aa lava, and Blocky lava


How are blocky lava and aa lava similar?

it hurts to walk on both, and they are both lava. Aa is a rough jagged surface, while I have no idea about blocky lava.
