physical geology

physical geology
Layers of the lithosphere (earth's crust) consists of different types of rocks that are all made ​​of magma freezing. Because of the endogenous and exogenous rocks are divided into three types, as follows.
igneous rock
Igneous rocks formed by magma freezing.
Frozen rock in the earth called intrusiva rocks (igneous rock in)
Frozen rock in the earth's surface called ekstrusiva rocks (igneous outside)


Examples of igneous rock
granite
Obsidian
Obsidian invisibility
diorite
Obsedian gray granite diorite Obsedian

stone Sedimen

Sediment / sludge formed by the erosion of igneous rocks (eroded), and then undergo a process of transporting and deposited elsewhere
Sedimentary rocks are distinguished by the type of substance transporter, namely:
Aeolis sediman stone: rock outcome of the transport by wind
Sedimen alluvial stones: the results of the transport of rock and formation by flowing water. Example: The delta at the mouth of the river
Stone sedimen marin: transport processes and outcomes of rocks shaped by the sea. Example: sand-dune at the beach
Sedimen glacial stone: rock transport and the formation process results by glaciers or ice flowing

Examples of sedimentary rocks
conglomerate
gypsum
Salt crystals
sandstone

Conglomerate Gypsum Crystal Salt Rock Sand

rock Melihan
Melihan rocks (metamorphic rock) are formed from rocks that experienced the change in temperature and pressure for a long time,
eg limestone (karst) turned into marble stone (marble). Stone melihan indistinguishable from the structure to be:
Layered (foliated)
Tak-coated (non-foliated)
