Sedimentary rocks are often deposited in layers, and frequently contain fossils.

Essentially, lithification is a process of porosity destruction through compaction and cementation.]]> 2018-01-30 21:48:11 UTC https://padlet.com/303994/swpjsxb8n0pu/wish/226354405 303994 https://padlet.com/303994/swpjsxb8n0pu/wish/226354883 This process is called compaction. 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 21:50:31 UTC https://padlet.com/303994/swpjsxb8n0pu/wish/226354883 303994 https://padlet.com/303994/swpjsxb8n0pu/wish/226355260 A metamorphic rock is a type of rock which has been changed by extreme heat and pressure. 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.]]> 2018-01-30 21:51:56 UTC https://padlet.com/303994/swpjsxb8n0pu/wish/226355260 303994 https://padlet.com/303994/swpjsxb8n0pu/wish/226355631 magma definition.

In other words, it differs from other igneous rock by being of volcanic origin. ...
