Flashcards

Igneous Rock Example

Granite and basalt are examples of igneous rocks, formed from cooled magma or lava.

Sedimentary Rock Formation

Sedimentary rocks, like limestone, form from compressed layers of sediment like shells, sand or mud.

Limestone Characteristics

Limestone is a sedimentary rock, formed from compressed shells and can vary in colors from white to gray and textures from smooth to rough.

Metamorphic Rock Transformation

Metamorphic rocks, like marble, are formed when existing rock is changed by heat and pressure.

Study Notes

Granite Characteristics

Granite is a coarse-grained igneous rock
Granite is composed of quartz, feldspar, mica, and other minerals
Granite is commonly found in mountainous regions

Limestone Formation

Limestone is formed through a process called sedimentation
Limestone forms from the accumulation of calcium carbonate shells and skeletons of marine organisms
Over time, these organic materials solidify and become sedimentary rock

Marble Characteristics

Marble is a metamorphic rock
Marble is formed from the transformation of limestone under heat and pressure
Marble is known for its smooth surface and varied color palette (white, grey, black, and others)

Smooth and Colored Rock

Marble is a smooth rock
Marble can vary in colour, ranging from white to black

Common Feature of Sedimentary Rocks

Sandstone and limestone are sedimentary rocks
They are formed from the accumulation and cementation of sediments
This process creates layered structures within these rock types
