Sedimentary Rock Video for Kids

 

Get amused watching this personally picked and really easy to understand Sedimentary Rock science kids video:

                                           Sedimentary Rocks

Sedimentary rocks can be defined as those rocks that are formed by sediments that are deposited over time. This sediment includes minerals, pieces of plants and some other organic matter. These rocks have layers of sediments. These layers are called strata and can be seen in exposed cliffs. These layers are formed when the sediment piles on the top of each other. These rocks are formed when the sediment hardens through a process called lithification. This is the most common type of rocks There are three different types of sedimentary rocks which are: – Classic, Organic, and Chemical.

Quick Facts: –

  • Almost 73% of the Earth’s current land surface is covered by sedimentary rocks but their contribution in the total volume of the crust is only 8%.
  • These rocks often have fossils of plants and animals from millions of years ago.
  • There are various types of these rocks. Some of them are limestone, sandstone, chalk, flint etc.
  • Table Salt is a good example of chemical sedimentary rocks.
  • Sedimentary rocks are formed at the earth’s surface from the weathered remains of igneous or metamorphic rocks or sometimes organic debris.
  • Flint is another example of these rocks. It is a hard and sedimentary form of the mineral quartz.
  • Cementation is the process in which minerals dissolve and hold the particles together to form a sedimentary rock.
  • Organic sedimentary rocks are formed organically derived sediments. These sediments come from animals and plants.
  • Shale is also a type of these rocks. It is clay that has been hardened and turned into rock.
