Lava is a liquid, not rocks.
Igneous rocks aren't affected by lava because they are made of cooled lava.
when lava emerges on out of mountain then the molten lava cool to form rocks.
I think the lava rocks are in the volcano on Mt. Puka.
extrusive rocks can form from Basaltic Lava and Andesitic Lava. :)
The molten rock that flows from a volcano is called lava.
It depends on the type of lava. The lava most people think of when they hear the word is basaltic lava. This lava cools into a black rock that may either have a ropey or jagged surface. It will often have bubbles near the surface of a flow. Over time, this rock may turn red as iron in it is oxidized. Other types of lava may form gray, white, or brownish rocks.
yes, from the rocks falling or the lava burning them or the big black smoke that comes after the eruption
