EZ's conversation with NIST Scientists!

🌍 Earth’s atmosphere weighs over a quadrillion tons—so why doesn’t it crush us? In this special Ask a Scientist feature, scientists from the National Institute of Standards and Technology (NIST) respond directly to an EZ Science Kids Ambassador’s big question about the weight of the atmosphere. 💨 What NIST Scientists Explain Even though the atmosphere has enormous mass: 💨 Air pressure pushes equally in all directions, not just downward ⚖️ The pressure inside our bodies balances the pressure outside 🌍 We are adapted to live under this pressure, so we don’t feel crushed 🧠 Big Science Ideas 🌍 Air has mass and weight 💨 Pressure is a force spread over an area ⚖️ Balanced forces don’t cause crushing 🎯 Why This Matters Understanding air pressure helps explain weather systems, airplanes, deep-sea pressure, and what changes when we leave Earth’s atmosphere. 🤝 Featured Scientists National Institute of Standards and Technology (NIST) Ask a Scientist Program ✨ EZ Science Kids Big questions.
