usually it depends on the rate of cooling of the lava....
No. Magma and lava are molten rock. When the cool they form igneous rock.
The rock becomes too hot that it must turn into liquid form (lava). This would usually mean that the rock had to have come into contact with lava first.
Extrusive igneous rock.
Extrusive igneous rock is formed from the crystallization of minerals as the lava cools.
Lava is made of the same chemical components that are found in many rock types (mostly silica and various metal oxides), only it is in a superheated, molten form. When the lava cools, the chemical components form the appropriate rock.
lava rock
Lava will cool to form extrusive igneous rock. The exact type would depend on the composition of the lava.
Rock minerals form from lava, magma or solutions.

lava is rock that is in its molted form ,lava is what magma's called when it reaches the surface.
