Earth & Space Science
You get to take a look at the different kinds of sedimentary rocks and how the Earths rock cycle works. Then help a scientist understand the ancient landscape using your knowledge of geology.
After completing this tutorial, you will be able to complete the following:
How are sedimentary rocks different from other types of rocks?
~ Unlike igneous rocks, which are formed when lava cools and hardens, and metamorphic rocks, which are formed through the application of heat pressure, sedimentary rocks are formed by layers of sedimentation that build up over long periods of time.
How do environmental factors influence the formation of sedimentary rocks?
~ Over long periods of time, various environmental factors, such as rain, flowing water, and temperature, break rocks into smaller pieces called sediment. With the help of wind and flowing water, sediment moves and collects in layers deep beneath the surface of various bodies of water. Over time, these layers harden into sedimentary rocks.
What organic materials are sometimes included in the layers of sedimentary rocks?
~ The remains of plants and animals are sometimes found in layers of sedimentary rocks.
What are the three types of sedimentary rocks?
~ The three types of sedimentary rocks are chemical, physical, and organic sedimentary rocks.
