What would Earth be like without its atmosphere? This reading passage encourages students to imagine a world without the protective layers of air that surround our planet. Readers discover how each atmospheric layer contributes to life by providing breathable air, blocking harmful ultraviolet radiation, burning up meteors, and helping regulate Earth’s temperature. Without this remarkable system, life as we know it simply couldn’t exist.

This worksheet builds informational reading skills by helping students identify how different parts of a system work together to achieve a common purpose. Students also strengthen their understanding of scientific explanations while learning vocabulary such as atmosphere, ultraviolet radiation, meteor, ozone layer, troposphere, and protection. Written in a warm, conversational voice, the passage helps students see Earth’s atmosphere as one of our planet’s greatest natural defenses.
