Sedimentary rocks are often deposited in layers, and frequently contain fossils. Note : Limestone and shale are common sedimentary rocks.

Essentially, lithification is a process of porosity destruction through compaction and cementation.

At the same time the particles of sediment begin to stick to each other - they are cemented together by clay, or by minerals like silica or calcite. After compaction and cementation the sedimentary sequence has changed into a sedimentary rock.]]> 2018-01-30 16:36:50 UTC https://padlet.com/3045721/kom8hodc9g88/wish/226180329 3045721 https://padlet.com/3045721/kom8hodc9g88/wish/226181265 Molten rock usually located deep within the mantle of the Earth that occasionally comes to the surface through cracks in the mantle or through the eruption of volcanoes. Note: When magma cools and solidifies, it forms igneous rock, of which lava is one type.

In chemical engineering, crystallization occurs in a crystallizer.

Sediment can be transported as pebbles, sand & mud, or as salts dissolved in water. Salts may later be deposited by organic activity (e.g. as sea-shells) or by evaporation.

Its name is from 'morph' (meaning form), and 'meta' (meaning change). The original rock gets heated (temperatures greater than 150 to 200 °C) and pressured (1500 bars). This causes profound physical and/or chemical change.
