The Rock Cycle

Basics

• Continual process that breaks down, alters, and re-forms rock into one of three types

• Types of rock can be converted to other types through Earth’s continual geological processes

Page 3: The Rock Cycle. Basics Continual process that breaks down, alters, and re-forms rock into one of three types Types of rock can be converted to other types

Three Types

• Igneous: – From cooling magma– Intrusive (Plutonic):

• Magma cooled below Earth’s surface (crystallization)

• granite

– Extrusive (Volcanic):• Cools quickly and ejected (ex: volcano)

• basalt

Page 4: The Rock Cycle. Basics Continual process that breaks down, alters, and re-forms rock into one of three types Types of rock can be converted to other types

• Sedimentary:– Result of sediments derived from

erosion/weathering being suppressed and cemented together (surface)

• Clastic: rock is physically eroded – Ex: Sandstone

• Chemical: dissolved material precipitates from water

– Ex: Limestone

Page 5: The Rock Cycle. Basics Continual process that breaks down, alters, and re-forms rock into one of three types Types of rock can be converted to other types

• Metamorphic:– Formed under extreme heat and pressure

• Foliated: heat/pressure force minerals to align and create layers

– Ex: Slate

• Unfoliated: not layered– Ex: marble

• The rock cycle demonstrates the relationships among the three major rock groups

• It is powered by the interior heat of the Earth

• As well as earth’s momentum and…

• The energy from the sun

• It involves processes on the Earth’s surface as well as the Earth’s interior

• It connects the “hydrologic cycle” with the “tectonic cycle”.

In Conclusion…
