Layers of the Earth for kids

Published on February 5, 2023 by

In this lesson, students will learn about the four layers of our Earth — atmosphere, hydrosphere, biosphere, and geosphere. The first and outermost layer of our planet is atmosphere, which primarily consists of gasses. From space to the surface of the Earth, atmosphere is divided into five layers, namely exosphere, thermosphere, mesosphere, stratosphere, and troposphere. When we reach the surface of Earth, we encounter the hydrosphere and biosphere. Hydrosphere includes all the water on Earth, while biosphere consists of all the life on Earth. Geosphere is the innermost layer that extends from Earth’s crust to the centre of Earth.

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.
