The foundation of a great rock collection is to identify your rocks by type. Geologists classify rocks into three basic groups based on how they were formed in nature. The types of rocks are: Igneous. Sedimentary. Metamorphic. To help you identify the types of rocks in your collection, let’s look at the characteristics that make up the three

Sedimentary Rocks. Any rock (igneous, sedimentary, or metamorphic) exposed at the Earth’s surface can become a sedimentary rock. The forces of wind, rain, snow, and ice combine to break down or dissolve (weather), and carry away (transport) rocks exposed at the surface. These particles eventually come to rest (deposited) and become hard rock

Chalk is formed out of superfine sediment called ‘ooze’. The formation of chalk starts with the death of the shells of marine animals, called ‘foraminifera’, marine algae, or other organisms that live at the bottom of the ocean, or in the waters above. The remains of these dead organisms collect together and form the sediment, ooze.

· Sedimentary rock forms under the sea. It forms in the following way: 1. As a result of weathering and erosion, bits of rock end up in lakes and rivers. Rivers transport bits of rock and deposit them on the bottom of the sea. This process is called sedimentation. 2. With time, more layers (strata) pile up and press down on the lower layers of rock.

· Sedimentary rocks are formed when weathered (broken down) pieces of sediment (fragments of minerals, rock, and organic material) are carried by moving water into a larger body of water like a lake or the ocean. Over time, the layers build up and the force of gravity compacts the layers. Minerals in the water seep between the empty

The sedimentary rock cycle is a process in which sediments are deposited, compacted, transformed into rock, and then eroded to form sediments again. It is a cycle because the same materials (sediments) keep going through the process again and again. Erosion is when pieces of rocks break off and fall down into the water or onto land.

This classification is essential to geologists as it provides critical information about the history of specific regions on Earth. These rocks change forms via the rock cycle.

: Smile and Learn-English · Sedimentary rocks are made from sediments – bits of dirt, sand, rocks, shells, bones, etc. – that settle into layers. The older layers are on the bottom. They settled first. With a little bit of pressure and time, the sediments stick together and form the rocks we see. If you have access to one, show your child a rock core sample.

Metamorphic Rock Facts For Kids. Metamorphic rocks form from other rocks. They change under heat and pressure. Marble comes from limestone. Slate was once shale or mudstone. These rocks often have layered patterns. They’re found in mountain ranges. Some can sparkle due to minerals. Quartzite comes from sandstone.
