Usually both.
aa lava
the amount of aa in it
the concentration of AA in the magma
A'a is not a kind of volcano. A'a is a texture that a lava flow can take on, characterized by a surface covered in sharp fragments. There is no particular height to the lava flow, or height of volcano from which such a flow erupts.
It is a lava flow, and has an AA (ah-ah) lava flow
If you mean bounce as like a rubber ball bounces, the answer is no. An AA battery will behave exactly the same if dropped regardless if it's fully charged or completely empty.
That depends on the chemistry of magma the volcano erupts - Basalt, andesite, rhyolite etc. but Generically the rock coming out of a volcano is called lava rock (pahoehoe or aa) but one can also get pumice or ignimbrites.

these are two ways on how: 1. a water spray can cool down a larva flow, 2. and using really heavy stones (10-40 tones)
