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 18:27:13 UTC https://padlet.com/306195/7l6jc6butrjm/wish/225179546 306195 https://padlet.com/306195/7l6jc6butrjm/wish/225179776 The rock cycle is 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.]]> 2018-01-26 18:27:45 UTC https://padlet.com/306195/7l6jc6butrjm/wish/225179776
