2. ROCK GROUPS
• Igneous
• Formed from a melt (molten rock)
• Plutonic (intrusive):slow cooling and crystallization
• Volcanic (extrusion): quick cooling at the surface
• Sedimentary
• Formed at the Earth’s surface
• Clastic (Mineral Fragments or grains, clays)
• Chemical (crystalline chemical/biochemical precipitates)
• Metamorphic
• Changed by pressure, temperature and fluids.

3. THE ROCK CYCLE

4. • To show how rocks slowly change
through time, scientists have created a
model called the rock cycle.
• It illustrates the processes that create
and change rocks.
