When common type of basaltic lava hardens it forms AA which has?

When common basaltic lava hardens, it forms aa lava, which has a rough, jagged texture characterized by sharp, angular fragments. This occurs due to its higher viscosity compared to pahoehoe lava, causing it to break apart as it flows. The formation of aa is typically associated with cooler temperatures and slower flow rates, resulting in a more fragmented surface.
