They are formed by the cooling of molten magma on the earth's surface. The magma, which is brought to the surface through fissures or volcanic eruptions, solidifies at a faster rate.]]> 2018-01-26 16:28:32 UTC https://padlet.com/3045371/be4kamvubdfv/wish/225126019 3045371 https://padlet.com/3045371/be4kamvubdfv/wish/225126405 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 16:29:32 UTC https://padlet.com/3045371/be4kamvubdfv/wish/225126405 3045371 https://padlet.com/3045371/be4kamvubdfv/wish/225127040 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 16:30:58 UTC https://padlet.com/3045371/be4kamvubdfv/wish/225127040 3045371 https://padlet.com/3045371/be4kamvubdfv/wish/225127673 In geology and related fields, a stratum (plural: strata) is a layer of sedimentary rock or soil, or igneous rock that were formed at the earth's surface, with internally consistent characteristics that distinguish it from other layers.]]> 2018-01-26 16:32:15 UTC https://padlet.com/3045371/be4kamvubdfv/wish/225127673
