If the crystallization process occurs at the Earth's surface, the rocks created are called extrusive igneous rocks. Intrusive igneous rocks are rocks that form within the Earth's solid lithosphere. Intrusive igneous rocks can be brought to the surface of the Earth by denudation and by a variety of tectonic processes.
Metamorphic rocks, formed by temperature and pressure changes inside the Earth. All three types of rock make up the Earth’s lithosphere, the outermost layer. The lithosphere averages about 100 kilometers in thickness. All igneous rocks began as magma (molten rock) which cooled and crystallized into minerals. Igneous rock, formed by the cooling of magma (molten rock) inside the Earth or on the surface. Sedimentary rocks, formed from the products of weathering by cementation or precipitation on the Earth’s surface.

It consists of the crust and the solid part of the upper mantle. It has an average thickness of about 35 km and is constantly changing due to processes such as volcanic eruptions, running water and wave action. In geology, rock or stone is a naturally occurring solid aggregate of one or more minerals or mineraloids. For example, the common rock granite is a combination of the quartz, feldspar and biotite minerals. The Earth's outer solid layer, the lithosphere, is made of rock. Sedimentary sandstone with iron oxide bands. Sedimentary rocks are formed at the earth's surface by the accumulation and cementation of fragments of earlier rocks, minerals, and organisms or as chemical precipitates and organic growths in water (sedimentation). Asthenosphere. Introduction. The asthenosphere is the layer of the Earth that lies below the lithosphere. It is a layer of solid rock that has so much pressure and heat the rocks can flow like a liquid. The rocks are less dense than the rocks in the lithosphere. This allows the tectonic plates in the lithosphere to move around on the Earth's surface by floating on the rocks that are slowly flowing like a liquid. Rocks in upper mantle. The rocks in the upper mantle can be part of the lithosphere or the asthenosphere. Lithosphere rocks are solid and rigid. Rocks below the lithosphere flow and break apart. 2. The earth's crust. The solid outer layer of the earth, the crust, consists of the CONTINENTAL CRUST, about 20-70 km thick, and the OCEANIC CRUST, which is thinner (5-10 km thick) and overlaid by the oceans. 3. Rocks and minerals. Rocks are solid pieces of the earth's crust, formed over very long periods of time The aggregate minerals forming the rock are held together by chemical bonds. The types and abundance of minerals in a rock are determined by the manner in which the rock was formed. Many rocks contain silica (SiO 2); a compound of silicon and oxygen that forms 74.3% of the Earth's crust. Sedimentary sandstone with iron oxide bands. Sedimentary rocks are formed at the earth's surface by the accumulation and cementation of fragments of earlier rocks, minerals, and organisms or as chemical precipitates and organic growths in water (sedimentation). Earth's lithosphere [edit]. Earth's lithosphere includes the crust and the uppermost mantle, which constitute the hard and rigid outer layer of the Earth. The concept of the lithosphere as Earth’s strong outer layer was described by A.E.H. Love in his 1911 monograph Some problems of Geodynamics and further developed by Joseph Barrell, who wrote a series of papers about the concept and introduced the term lithosphere. Quick cooling lavas are called volcanic rocks. Magma that cools slowly creates rocks like granite, which have large minerals that can be seen with the naked eye. These igneous rocks cool inside the lithosphere, and are called plutonic rocks. Sedimentary rocks form at the Earth’s surface in two main ways. Clastic material (pieces of other rocks or fragments of skeletons) may become cemented together and chemical precipitation and evaporation can form sedimentary rocks. Igneous rock, formed by the cooling of magma (molten rock) inside the Earth or on the surface. Sedimentary rocks, formed from the products of weathering by cementation or precipitation on the Earth’s surface.
