Sedimentary rocks are often deposited in layers, and frequently contain fossils. Note : Limestone and shale are common sedimentary rocks.]]> 2018-01-26 17:08:22 UTC https://padlet.com/3049411/b4wlm6rsuty6/wish/225144374 3049411 https://padlet.com/3049411/b4wlm6rsuty6/wish/225144913 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 17:09:33 UTC https://padlet.com/3049411/b4wlm6rsuty6/wish/225144913 3049411 https://padlet.com/3049411/b4wlm6rsuty6/wish/225145679 Igneous rock (derived from the Latin word ignismeaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava.]]> 2018-01-26 17:11:09 UTC https://padlet.com/3049411/b4wlm6rsuty6/wish/225145679
