2. What is igneous rock?
•Igneous rocks are defined as types of
rocks that are formed when molten rock
(rock liquefied by intense heat and
pressure) cools to a solid state.

3. What are igneous rock
made of?
•Igneous rocks come from melted rock
material, or magma, that lies beneath
Earth's surface. Igneous rocks form
when magma from inside the Earth
moves toward the surface, or is forced
above the Earth's surface as lava and
ash by a volcano. Here it cools and
crystallizes into rock.

4. What are the 2 main types
of igneous rocks?
•Igneous rocks are divided into two
groups, intrusive or extrusive,
depending upon where the molten rock
solidifies.

7. Types of igneous rock
example
•Granite - it s formed when magma cools
below the earth surface
•Basalt - it is formed by rapid cooling of
lava above the earth surface
•Pumice-it is a light igneous rock with
thousands of tiny bubbles in them.
•And others
