Hank describes the desperate need many organisms have for nutrients (specifically nitrogen and phosphorus) and how they go about getting them via the nitrogen and phosphorus cycles.

The geographic north pole doesn't always line up with the magnetic north pole, but what do scientists know about this flipping field?

The spiral of the Milky Way is not as smooth as we once thought because an arm not so far from home appears to be broken! And we may have discovered the answer to why a local asteroid puts on the appearance of a comet.

Waterfalls are pretty amazing, but have you ever wondered how they form? Jessi's got the answer! Join her to learn all about how rivers carve waterfalls and then take a look at Angel Falls, the tallest waterfall in the world!

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...

Cliffs and canyons, beaches and dunes, floodplains and river valleys, plateaus and mountains — these are all products of a restless Earth. In today’s episode we’re going to take a closer look at how landforms greatly influence how people...

At the beginning of the Triassic Period, with the continents locked together from pole-to-pole in the supercontinent of Pangea, the world is hot, flat, and very, very dry. But then 234 million years ago, the climate suddenly changed for...

Nature creates some pretty amazing things, and one of the largest of these is The Grand Canyon!

It's Earth Science time!!!! In this field, natural philosophers were asking questions like, what’s up with fossils? Are they the remains of extinct organisms? Or are they so-called “sports of nature”—rocks that just happen to look like...
