Rock Cycle
Khaki Strebel-6th grade Main Objectives
-Students will be able to explain the rock cycle-Students will be able to identify the main types of rocks in the rock cycle.-Students will be able to give examples of each of the main types of rocks.

Rock Cycle Overview
Khaki Strebel 2009
Sediment Sediment is formed from
weather and erosion.
Sediment-small, solid pieces of material that come from rocks or organisms.
Khaki Strebel 2009
Deposition Deposition occurs after the
sediment is formed.
Deposition-process in which sediment is laid down in new location.
Khaki Strebel 2009
Cementation and Compaction Next cementation and
compaction happens. (lithification)
Cementation-the process by which dissolved minerals crystallize and glue particles of sediment together.
Compaction-the process by which sediments are pressed together under their own weight.
Khaki Strebel 2009
Sedimentary Rocks Sedimentary rock- a type
of rock that forms when particles from other rocks or the remains of planets and animals are pressed and cemented together.
Examples: Sandstone Shale Conglomerate
Khaki Strebel 2009
Heat and pressure When heat and pressure
are applied to sedimentary rocks they form metamorphic rocks
Khaki Strebel 2009
Metamorphic Rock Metamorphic rock- a type
of rock that forms form an existing rock that is changed by heat, pressure, or chemical reaction.
Examples Quartzite Gneiss Slate

Magma and Lava This causes the rocks to
melt.
Khaki Strebel 2009
Cooling Cooling comes after the
melting. The rate of cooling is
effected by the location of the magma/lava.
This also effects what kind of igneous rock is formed.
Khaki Strebel 2009
Igneous Rock Igneous rock-a type of rock
that forms from the cooling of molten rock at or below the surface.
Intrusive and extrusive Examples
Granite Obsidian Rhyolite

Rock Cycle Review
Khaki Strebel 2009
Review sedimentary, metamorphic,
igneous
Sedimentary-sandstone, shale, conglomerate
Metamorphic- quartzite, gneiss, slate
Igneous- granite, obsidian, rhyolite
What are the 3 types of rocks?
Can you give me any examples mentioned in this PowerPoint for each of the 3 types of rocks?
