Welcome To The Rock Cycle!!! : Welcome To The Rock Cycle!!! Here We Will Explore The Creation And Destruction Of Rocks!!!

THE THREE TYPES OF ROCK : THE THREE TYPES OF ROCK The 3 types of rock are: Igneous Sedimentary Metamorphic All rocks are classified as one of these three types based on how it was created. Igneous Rocks From About Geology.Com

HOW THEY ARE FORMED?? : HOW THEY ARE FORMED?? Every type of rock forms differently. Metamorphic Rocks: form from great heat and pressure that changes rocks into new forms. Igneous Rocks: form from cooling magma that crystallizes. Sedimentary Rocks: form from a process called compaction.

IGNEOUS ROCKS : IGNEOUS ROCKS Igneous rocks form from cooling magma. Common places to find igneous rocks are near areas of volcanic action or where volcanoes once erupted.

2 groups of Igneous Rocks : 2 groups of Igneous Rocks Igneous rocks are grouped by how they cooled. If they cooled underground they are called Intrusive. If they cooled above ground they are Extrusive. Granite from About Geology .Com Almost all crystals are igneous rocks. Picture from Geology.com

INTRUSIVE IGENOUS ROCKS : INTRUSIVE IGENOUS ROCKS COOL UNDERGROUND. COOL VERY SLOWLY AND CAN MELT OTHER ROCK MATERIALS WHILE IT COOLS TOO. THIS CAN CREATE MORE THAN ONE COLOR IN THESE TYPES OF ROCKS. BECAUSE THEY COOL SLOWLY THEY CREATE LARGE CRYSTALS.

EXTRUSIVE IGNEOUS ROCKS : EXTRUSIVE IGNEOUS ROCKS COOL QUICKLY. FORM SMALL CRYSTALS BECAUSE OF FAST COOLING. COOL ABOVE THE SURFACE OF THE EARTH. DO NOT GENERALLY MIX A LOT OF OTHER MATERIALS WITH THEM WHILE COOLING.

IN OUR EXPERIMENT… : IN OUR EXPERIMENT… The dissolving Borax in the hot water represented crust melting in hot magma. The cooling of the magma into crystals was shown by the Borax crystals forming on the pipe cleaner. Some Igneous rocks will repeat this process over and over, while others will weather on the surface and become sediment, which will form sedimentary rock.

SEDIMENTARY ROCK : SEDIMENTARY ROCK IS THE MOST COMMON TYPE OF ROCK. FORMS IN LAYERS AS SEDIMENT STACKS ON TOP OF EACH OTHER. THE WEIGHT OF THESE LAYERS CAUSES COMPACTION WHICH FORMS THE ROCKS! Picture from nasa.geology.gov

WEATHERING AND EROSION : WEATHERING AND EROSION Weathering, and weathering with material transportation (Erosion), causes the sediment layers to form and build on each other. Picture from unl.edu

SO WHAT DOES THAT CAUSE? : SO WHAT DOES THAT CAUSE? THIS CAUSES A LOT OF PRESSURE. THE MOISTURE TRAPPED IN THE SEDIMENT PLUS THE PRESSURE CEMENTS THE SEDIMENTS TOGETHER KIND OF LIKE PACKING SNOW FLAKES TOGETHER TO FORM A SNOW BALL. ONCE THE MOISTURE ESCAPES ROCK IS FORMED. EARLY FORMS OF SEDIMENTARY ROCK ARE LAYERS OF CLAY.

SEDIMENTARY ROCK : SEDIMENTARY ROCK TYPICALLY NOT AS HARD AS MOST OF THE OTHER TYPES OF ROCK. CAN BE MADE OF ONE OR MORE TYPES OF SEDIMENT. WILL ERODE TO FORM NEW SEDIMENT OR MELT IN THE MANTLE TO FORM MAGMA AND THEN LATER IGNEOUS ROCK.
