Igneous rock is formed through the cooling and solidification of magma or lava.]]> 2018-01-26 18:28:36 UTC https://padlet.com/3095331/gj7nkmm9nz0o/wish/225180139 3095331 https://padlet.com/3095331/gj7nkmm9nz0o/wish/225180887 Rock that has formed through the deposition and solidification of sediment, especially sediment transported by water (rivers, lakes, and oceans), ice ( glaciers ), and wind. Sedimentary rocks are often deposited in layers, and frequently contain fossils. Note : Limestone and shale are common sedimentary rocks.]]> 2018-01-26 18:30:19 UTC https://padlet.com/3095331/gj7nkmm9nz0o/wish/225180887 3095331 https://padlet.com/3095331/gj7nkmm9nz0o/wish/225181418 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' (meaningchange). The original rock gets heated (temperatures greater than 150 to 200 °C) and pressured (1500 bars). This causes profound physical and/or chemical change.]]> 2018-01-26 18:31:26 UTC https://padlet.com/3095331/gj7nkmm9nz0o/wish/225181418 3095331 https://padlet.com/3095331/gj7nkmm9nz0o/wish/225182061 In geology and related fields, a stratum (plural: strata) is a layer of sedimentary rock or soil, or igneous rockthat were formed at the earth's surface, with internally consistent characteristics that distinguish it from other layers.
