Imagine a giant, invisible blanket wrapping around our Earth, keeping us safe and snug. That’s the atmosphere! The atmosphere is the protective layer of gases that surrounds our planet, extending from the surface all the way up into space. It’s like our own personal shield, shielding us from the harshness of outer space and providing the air we breathe to sustain life. But it’s not just a passive layer; it’s a dynamic system that influences everything from our weather to the climate. Let’s embark on a journey to explore this incredible layer that makes life on Earth possible!
