Sedimentary rocks are often deposited in layers, and frequently contain fossils. Note : Limestone and shale are common sedimentary rocks]]> 2018-04-26 15:53:20 UTC https://padlet.com/3049561/l78zffqsvnbr/wish/255710121 3049561 https://padlet.com/3049561/l78zffqsvnbr/wish/255711185 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.]]> 2018-04-26 15:55:26 UTC https://padlet.com/3049561/l78zffqsvnbr/wish/255711185 3049561 https://padlet.com/3049561/l78zffqsvnbr/wish/255713824 The Rock Cycle is a group of changes. Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock. Igneous rock forms when magma cools and makes crystals.]]> 2018-04-26 16:00:08 UTC https://padlet.com/3049561/l78zffqsvnbr/wish/255713824 3049561 https://padlet.com/3049561/l78zffqsvnbr/wish/255716822 Weathering is the breaking down of rocks, soil, and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, water, and biological organisms.]]> 2018-04-26 16:06:13 UTC https://padlet.com/3049561/l78zffqsvnbr/wish/255716822 3049561 https://padlet.com/3049561/l78zffqsvnbr/wish/255717392 In earth science, erosion is the action of surface processes that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transport it away to another location.]]> 2018-04-26 16:07:11 UTC https://padlet.com/3049561/l78zffqsvnbr/wish/255717392 3049561 https://padlet.com/3049561/l78zffqsvnbr/wish/255717889 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 16:08:12 UTC https://padlet.com/3049561/l78zffqsvnbr/wish/255717889 3049561 https://padlet.com/3049561/l78zffqsvnbr/wish/255718344 the binding together of particles or other things by cement.]]> 2018-04-26 16:09:12 UTC https://padlet.com/3049561/l78zffqsvnbr/wish/255718344 3049561 https://padlet.com/3049561/l78zffqsvnbr/wish/255718823 compaction.
