General purpose of this lecture is to present on Rocks and Weathering Rock Cycle. For thousands, even millions of years, little pieces of our earth have been eroded–broken down and worn awayby wind and water. These little bits of our earth are washed downstream where they settle to the bottom of the rivers, lakes, and oceans. These layers are pressed down more and more through time, until the bottom layers slowly turn into rock. Here briefly present on some Weathering Rock Cycle: Sedimentary Conglomerate, Sedimentary Gypsum, Sedimentary Limestone, Sedimentary Sandstone and Sedimentary Shale.
