Whatever is inside the earth is very hot. The trail of clues leads to the model of a metallic core surrounded by a rocky mantle. Huge, slow convection currents rise up, often resulting in earthquakes and volcanoes.

The 5.8-magnitude quake that occurred in Virginia was felt up and down the Eastern United States and even in Canada. In contrast, a similar magnitude earthquake on the West Coast would be felt more locally. Geologists say this difference...

The video is a lecture presentation on the extraction of metals. The presenter begins by discussing how the method used to extract a metal from its ore depends on the metal's reactivity. The lecture then covers the extraction of iron...

Jupiter's second Galilean Moon, Europa.

This video tutorial teaches the art of making a traditional pie crust from scratch, focusing on the importance of cold ingredients and the technique of incorporating butter and shortening into flour. It emphasizes not overworking the...

In this video, students will learn what happens when stresses build up in rocks along a fault and what happens when these stresses are released. Viewers will come to understand how these stresses relate to earthquakes and how they can be...

Before taking a deep dive into the geology of the ocean's layers, let's review the basics of ocean life. What are the different sections of the ocean? What types of creatures live in each region?
