Igneous Rocks

• Igneous Rocks • Igneous is Latin for FIRE• Forms when molten

rock cools and hardens• Can form deep in Earth

or on surface

Page 3: Igneous Rocks Explain how the cooling rate of magma affects the texture of igneous rock.

Igneous Rocks

• Two types:– Intrusive igneous rock • Rock formed from cool

and solidification of magma beneath Earth’s surface

• Slow cooling magma = large mineral crystals

• Large crystals = course (rough) grained rock

Page 4: Igneous Rocks Explain how the cooling rate of magma affects the texture of igneous rock.

Igneous Rocks

– Extrusive igneous rock • Rock that forms as result of volcanic activity or cools on Earth’s surface

• Fast cooling = small mineral crystals

• Small crystals = fine (smooth) grained rock
