Science 2: Earth's Spheres

Sabrina talks about two of the four spheres that make up our planet; The Geosphere and the Biosphere. What's in these spheres? How do they affect us?

In this episode, Sabrina talks about the Hydrosphere and the Atmosphere and what is contained in each one.

We've already talked about how the Earth is divided into four spheres (The Hydrosphere, the Biosphere, the Geosphere, and the Atmosphere). But, how do these different spheres interact with each other?

In this episode, Sabrina gives us a real-world example of how the Hydrosphere and Geosphere affect each other in the form of Weathering and Erosion.

So... what makes the wind? You might be surprised to learn that it has to do with two of Earth's spheres: the hydrosphere and the geosphere.

Today we're going to take a hike up Mt. Kilimanjaro so we can talk about how the geosphere changes based on many different things.

So, what's the difference between "weather" and "severe weather"? Is it just how hard the wind is blowing? Is it just thunder and lightning? In this episode, Sabrina talks to us about what makes severe weather and how it interacts with the geosphere and biosphere.

Today we're going down down down into the ocean to see what habitats await us there. We'll see how the hydrosphere affects the biosphere!

Hey Earth Scientists! Ready to dive into a fun-filled journey through Earth's four amazing systems?

Learning this song will help students remember how erosion works to change the land around us.

Learning about rocks and mountains is cool! Now you can learn how they change over a really long time!

Play this animated video to learn more about the atmosphere - including all of the different layers of gases. There is also a quiz to test yourself.

Check out this slide show about the three major layers that make up our Earth and the living conditions and resources that we have. There's a quiz after the slide show.

This slide show has images and information about different kinds of severe storms. Watch the show and then test yourself with the quiz.
