Traditionally, geography is studied as two interconnected parts: physical geography and human geography. For the first half of this series, we will be focusing on physical geography, which is all about recognizing the characteristics of...

A “tipping point” is when a system, with just a small amount of additional energy, is pushed from one stable state to another suddenly and dramatically. This can be a chair falling backwards. Or it can be a major earth system collapsing....

Learn about earth's 4 major geological subsystems and how they interact with one another with this fun educational music video and parents. Brought to you by KLT. Don't forget to sing along.

Breakthrough Starshot is a future space mission that plans to send tiny, laser-powered probes to another star system, aiming to reach Proxima b, a potentially Earth-like planet. These spacecraft will travel at 20% the speed of light...

In this video Paul Andersen describes the four major spheres on planet Earth. The geosphere makes up the mass of the planet and includes the major landforms. The hydrosphere is all of the water and the atmosphere is all of the gases. ...

In this video Paul Andersen explains how plate tectonics explains the large-scale system interactions on our planet. Large plates float on the mantle and interact to form the major landforms on the planet. Evidence for plate tectonics...

There's an invisible force shaping our lives, affecting the weather, climate, land, economy, and just whether a flag looks majestic or not - we're talking about the wind! Today we’re going to go into the science of where the wind comes...
