cementation - process of binding and hardening of sediments into hard rock, compaction - process by which overlying pressure from rocks and soil reduces the size or volume of sediments, decomposition - the process by which dead plants and animals decay or rot, deposition - process by which weathered and eroded material is dropped off by wind, water, and ice, erosion - the movement of weathered material by wind, water, or ice (e.g. glaciers), evidence - facts or other information supporting a claim or proposition, fossil fuels - fuels formed over millions of years from the remains of ancient plants and animals; examples include coal, petroleum (oil) and natural gas, landforms - a physical structure on Earth that occurs naturally, models - a picture, idea, or object that represents an object, a system, or process and is used to help with understanding; models have advantages and limitations, organism - a living thing that grows, reproduces, responds to its environment, and can function on its own, process of formation - the method by which a substance or object is formed, sedimentary rock - rock that forms when sediments are compacted and cemented together, weathering - process by which exposed rock is broken down by rain, frost, wind, or other elements of weather, petroleum - formed in areas that were oceans millions of years ago from dead microscopic plants and animals, Coal - formed in areas that were swamps millions of year ago, U-Shaped Valley - formed from the movement of a glacier weathering and eroding rock, Canyon - shaped from the movement of a river weathering and eroding rock, Sand Dune - A hill of sand, eroded and deposited by wind, cementation - takes place as minerals in water bind or make the sediments hold together, compaction - happens as layers of sediment are deposited on top of each other adding pressure to the layer below, frost wedging - Process that splits rock when water seeps into cracks, then freezes and expands.,
