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.
A'a can occur at composite volcanoes, but block lava flows, which are far more viscous, are more common.
Block-lavas is considered to be the tougher and thicker form of lava.
Aa lava is a basaltic lava with a flow characterized by rough surfaces of clinker.
they poduce shield volcanoes like the hawiian islands
Lava Plateaus
Aa and pahoehoe lavas are both basaltic in composition. The lava from composite volcanoes is likely to be granitic.

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.

It is called aa
The difference between Pahoehoe lava and AA lava is that pahoehoe lava is smooth and AA lava is jagged.
Lava Plateaus
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.
Pahoehoe lava, Aa lava, and Blocky lava
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.
