The four spheres make our planet the lovely place we know it to be. In this video, Sabrina Cruz will describe two of Earth’s spheres — geosphere and biosphere. Geosphere forms the skeleton of our planet. All of the other spheres are made on top of it. All living things on Earth make up the biosphere. This characteristic distinguishes it from the geosphere, which mainly includes non-living things. No matter how different they are, they work together to help make our planet the way it is.
This video satisfies the 5-ESS2-1 requirement of fifth-grade science proficiency.
Students who demonstrate understanding can: 5-ESS2-1. Develop a model using an example to describe ways the geosphere, biosphere, hydrosphere, and/or atmosphere interact.
