WebGranite (cooled from magma, known as an intrusive igneous rock) and basalt (cooled from lava, known as an extrusive igneous rock) are two types of igneous rocks. Sedimentary rocks are formed by smaller pieces of sand and mud stick together in layers. Examples include: sandstone, mudstone ,shale, siltsone, limestone, and more.

Granite Properties, Formation, Composition, Uses
WebGranite, Devon Granite is formed when viscous (thick/ sticky) magma slowly cools and crystallises long before it is able to reach the Earth’s surface. Granite is a coarse-grained, crystalline rock, made up mostly of three minerals called quartz (grey, glassy looking), feldspar (usually white or pinkish, blocky shapes), and shiny black or pale mica. WebObsidian is an igneous rock that forms when molten rock material cools so rapidly that atoms are unable to arrange themselves into a crystalline structure. It is an amorphous material known as a " mineraloid ." The result is a volcanic glass with a smooth uniform texture that breaks with a conchoidal fracture (see photo). in which organ sertoli cells are found
