In this video you will learn about the dynamic rock cycle. Plant roots help to create new soil from the solid rock and they get nutrients and support from the soil. This solid rock is often sandstone or granite. They are made up of...

In this video, the concept of the law of superposition is explained, which states that younger rock layers are found on top of older rock layers in sedimentary rocks. Additionally, the video introduces the concept of index fossils, which...

What happens when you discover a dinosaur? Paleontologist Kenneth Lacovara details his unearthing of Dreadnoughtus -- a 77-million-year-old sauropod that was as tall as a two-story house and as heavy as a jumbo jet -- and considers how...

Upon viewing the Exploring Fossils video series, students will be able to do the following: Explain that fossils are the ancient remains or traces of once-living things. Understand that fossils come in a wide range of shapes, sizes, and...

A fossil is a trace of a living thing left in rock. Fossils offer a three-part challenge - first to reconstruct the organism itself, then to reconstruct the world it lived in, then to understand its place in time and evolution.

Where are fold mountain ranges found on our planet? And how do the movements of tectonic plates affect their growth? Earth Science - Geology - Learning Points. A Fold mountain forms over millions of years by a process called orogeny....
