Trang 5Extrusive igneous rocks are cooled quickly so small
crystals form (e.g basalt)
Intrusive igneous rocks are cooled more slowly so
large crystals form (e.g granite)
Igneous rocks are formed by the solidification of
molten material from below the earth's surface
Igneous rocks
Trang 6Basalt
What differences do you notice between these two igneous rocks?
Granite has visible crystals
Igneous rocks – crystal size
Trang 7Igneous rocks
Basalt
Trang 8Igneous rocks
Trang 9Basalt pillars
These pillars were formed when lava cooled on the
Earth’s surface

What is the rock cycle?
Trang 16Metamorphic rocks are formed by the effect of
extreme pressures and temperatures deep within the
Earth
This alters the structure of the existing rock
Metamorphic rock - formation

Trang 19Continent collision causes metamorphism and huge folds like this one in Scotland.
