What type of rocks form from lava after a volcanic eruption?
Igneous rocks are formed from the cooling and solidifying of magma. The resulting rock can be instrusive (magma cooling within the crust) and extrusive (lava cooling on the surface). The most common kind of rocks are Granite (intrusive) and Basalt (extrusive).
What trait is an intrusive igneous rock?

What does a fine-grass igneous rock forms?
A fine grained igneous rock forms from Lava that escapes from the earth crust to the surface and cools and solidifies rapidly.
From what material does extrusive rocks form?
