THE ROCK CYCLE
Created by Kayla Rooney
New Terms
• Weathering: the various mechanical & chemical processes that cause exposed rock to decompose.
• Lithification: the process by which materials are converted into solid rock through compaction or cementation.
• Sediment: minerals or organic matter deposited by water, air or ice.
• Metamorphism: a change in the structure of a rock due to natural processes such as, pressure or heat.
• Crystallization: the act or process of crystallizing.
• Solidification: a change from a liquid or gaseous state to a solid form.
Sedimentary Rocks
• Formed from pre-existing rocks or pieces of once-living organisms.
• Formation occurs through the processes of deposition and lithification on Earth’s surface.
• Distinct layering and bedding
Examples of Sedimentary
Rocks
Igneous Rocks• Formed when hot, molten
rock crystallizes and solidifies.
• Found near active tectonic plate boundaries
• Two types: 1) Intrusive (Plutonic): Formed when magma is trapped deep inside the Earth.
2) Extrusive (Volcanic): Formed when magma exits and cools above the Earth’s surface.
Examples of Igneous Rocks
Metamorphic Rocks• Formed from other types
of rocks (sedimentary, igneous or other metamorphic rocks)
• Formed from the processes of high heat and high pressure deep within the Earth.
• The final result is a more dense and compact rock with a new mineral make up.
Examples of Metamorphic
Rocks
