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 16:42:15 UTC https://padlet.com/3049561/ykcereff6ss2/wish/225132600 3049561 https://padlet.com/3049561/ykcereff6ss2/wish/225133618 Sedimentary rocks form when mud and sand are deposited in layers on the Earth's surface. The layers are deposited in many environments including oceans, rivers and deserts. These layers of sand and mud are later buried. The weight of overlying layers compresses the mud and sand to form solid rock.]]> 2018-01-26 16:44:17 UTC https://padlet.com/3049561/ykcereff6ss2/wish/225133618 3049561 https://padlet.com/3049561/ykcereff6ss2/wish/225134263 Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". The original rock is subjected to heat and pressure, causing profound physical or chemical change.]]> 2018-01-26 16:45:33 UTC https://padlet.com/3049561/ykcereff6ss2/wish/225134263 3049561 https://padlet.com/3049561/ykcereff6ss2/wish/225134708 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.]]> 2018-01-26 16:46:30 UTC https://padlet.com/3049561/ykcereff6ss2/wish/225134708
