Sedimentary rocks are often deposited in layers, and frequently contain fossils. ]]> 2018-04-26 15:25:33 UTC https://padlet.com/304567/5ev9wanhbjae/wish/255696069 304567 https://padlet.com/304567/5ev9wanhbjae/wish/255696144 Rock that was once one form of rock but has changed to another under the influence of heat, pressure, or some other agent without passing through a liquid phase.]]> 2018-04-26 15:25:44 UTC https://padlet.com/304567/5ev9wanhbjae/wish/255696144 304567 https://padlet.com/304567/5ev9wanhbjae/wish/255696219 an idealized cycle of processes undergone by rocks in the earth's crust, involving igneous intrusion, uplift, erosion, transportation, deposition as sedimentary rock, metamorphism, remelting, and further igneous intrusion.]]> 2018-04-26 15:25:53 UTC https://padlet.com/304567/5ev9wanhbjae/wish/255696219 304567 https://padlet.com/304567/5ev9wanhbjae/wish/255696259 wear away or change the appearance or texture of (something) by long exposure to the air.]]> 2018-04-26 15:25:58 UTC https://padlet.com/304567/5ev9wanhbjae/wish/255696259 304567 https://padlet.com/304567/5ev9wanhbjae/wish/255696309 the process of eroding or being eroded by wind, water, or other natural agents.]]> 2018-04-26 15:26:03 UTC https://padlet.com/304567/5ev9wanhbjae/wish/255696309 304567 https://padlet.com/304567/5ev9wanhbjae/wish/255696348 In geology and related fields, a stratum 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.]]> 2018-04-26 15:26:10 UTC https://padlet.com/304567/5ev9wanhbjae/wish/255696348 304567 https://padlet.com/304567/5ev9wanhbjae/wish/255696410 The act or process of commenting or criticising; exposition.
