Igneous rock is formed through the cooling and solidification of magma or lava.]]> 2018-04-26 16:26:40 UTC https://padlet.com/3049411/5izcnt9k2tp4/wish/255727040 sedimentary rock 3049411 https://padlet.com/3049411/5izcnt9k2tp4/wish/255732463 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.]]> 2018-04-26 16:36:59 UTC https://padlet.com/3049411/5izcnt9k2tp4/wish/255732463 Metamorphic RockA 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. 3049411 https://padlet.com/3049411/5izcnt9k2tp4/wish/255734029 2018-04-26 16:40:05 UTC https://padlet.com/3049411/5izcnt9k2tp4/wish/255734029 .
