There shouldn’t be any standing water in the cup. Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Mini Me Geology’s sedimentary rock samples provide a wide range of sediment types, colors, and textures because they were made in rivers, lakes, oceans and deserts. After many years, these materials finally settle down through the process of sedimentation. These geological changes can be due to heat and temperature from the recrystallizing rock being found deep within the earth's crust.

To learn more about the three kinds of rocks (sedimentary, metamorphic, and igneous) and how they are changed in the steps of the rock cycle, see our science lesson! They are formed on or near the Earth’s surface from the compression of ocean sediments or other processes. Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation. These rocks … The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.

Organic detrital rocks form when parts of plants and animals decay in the ground, leaving behind biological material that is compressed and becomes rock. The other is chemical rock, produced from the dissolution and precipitation of minerals. Do this simple science project using a plastic glass, rock salt and some water to learn about deposition. Dissolution is a form of weathering—chemical weathering. Go out and gather a handful or two of as many different types of dirt, mud, sand, and pebbles as you can find, putting them in the bottle as you go to create your own 'sedimentary layers.' When the chemical-rich water makes its way into a cave, the water evaporates and leaves behind calcium carbonate on the ceiling, forming a stalactite, or on the floor of the cave, creating a stalagmite. On your piece of paper, draw a picture of the layers in the bottle, and next to each layer, write what it’s made out of -- pebbles? These three processes create the raw materials for new, sedimentary rocks. These types of rocks are formed as sediments; such as sand, pebbles, minerals, plants or animals, and are moved together by a force like water. Sedimentary rocks are, as the name suggests, formed from the buildup of sediment. So, if you have a dinosaur or a geology unit coming up, this would be a perfect addition! Sedimentary Rocks are rocks formed from rock fragments and organic matter. Sedimentary rocks are formed when dirt, sand, and small bits of rocks (also known as sediment) settle down and stick together, often at the bottom of a lake. Set the bottle somewhere where there’s good light and it won’t be disturbed. Look closely at the sediments that have settled at the bottom of the bottle. Let the “rock” sit and harden for at least 2 days. When the bottle is about 1/3 full, take it home, fill it the rest of the way with water, and close it tightly with the cap.
