Igneous Rock Example
Igneous Rock Example
Granite and basalt are examples of igneous rocks, formed from cooled magma or lava.
Sedimentary Rock Formation
Sedimentary Rock Formation
Sedimentary rocks, like limestone, form from compressed layers of sediment like shells, sand or mud.
Limestone Characteristics
Limestone Characteristics

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
