Geology Rock Cycle, Wheathering by Jaelyn Riddle https://padlet.com/jaelyn_riddle/j9auz184wll5 Made with Denae :D en-us 2018-05-29 20:23:58 UTC 2018-05-29 20:40:11 UTC hello@padlet.com The Rock Cycle jaelyn_riddle https://padlet.com/jaelyn_riddle/j9auz184wll5/wish/264366884 The Rock Cycle is a group of changes. Igneous rock can change into sedimentary rock or into metamorphic rock. Metamorphic rock can change into igneous or sedimentary rock. Igneous rock forms when magma cools and makes crystals.]]> 2018-05-29 20:27:20 UTC https://padlet.com/jaelyn_riddle/j9auz184wll5/wish/264366884 Weathering jaelyn_riddle https://padlet.com/jaelyn_riddle/j9auz184wll5/wish/264367456 Weathering is the process that breaks down rocks. Many things cause weathering, including climate changes, and Erosion, Erosion breaks rocks down further and then moves them. Forces like wind and water move the rock pieces. They mix with matter like sand to become sediment. Weathering and erosion help shape Earth’s surface. They are part of a process called the rock cycle. Rocks are hard and strong, but they do not stay that way forever. Forces like wind and water break down rocks through the processes of weathering Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clay) and soluble salts. These reactions occur particularly when the water is slightly acidic.]]> 2018-05-29 20:29:35 UTC https://padlet.com/jaelyn_riddle/j9auz184wll5/wish/264367456 Physical Weathering jaelyn_riddle https://padlet.com/jaelyn_riddle/j9auz184wll5/wish/264367849 Physical weathering is caused by the effects of changing temperature on rocks, causing the rock to break apart. The process is sometimes assisted by water. ]]> 2018-05-29 20:32:07 UTC https://padlet.com/jaelyn_riddle/j9auz184wll5/wish/264367849 How does it occur? jaelyn_riddle https://padlet.com/jaelyn_riddle/j9auz184wll5/wish/264368007 Either through repeated melting and freezing of water (mountains and tundra) or through expansion and contraction of the surface layer of rocks that are baked by the sun (hot deserts).

Weathering is the breakdown of rocks at the Earth’s surface, by the action of rainwater, extremes of temperature, and biological activity. It does not involve the removal of rock material.

Weathering involves no moving agent of transport.]]> 2018-05-29 20:34:14 UTC https://padlet.com/jaelyn_riddle/j9auz184wll5/wish/264368205 The 3 types of Weathering are, jaelyn_riddle https://padlet.com/jaelyn_riddle/j9auz184wll5/wish/264368452 physical, chemical and biological.
