4. Conclusions. Tantalum nitride films were deposited on ceramic substrates (pre-sputtered with underlayer and 100-nm-thick aluminum oxide) by DC reactive magnetron sputtering using a Ta target under a typical base pressure of 10 â7 Torr.
Earth's atmosphere is a thin blanket of gases and tiny particlesâtogether called air. Without air, the Earth would just be another lifeless rock orbiting the Sun. Although we are rarely aware of it, air surrounds us. We are most aware of air when it moves, creating wind.
What is the atmosphere of Earth made of? Earth's atmosphere is 78% nitrogen, 21% oxygen, 0.9% argon, and 0.03% carbon dioxide with very small percentages of other elements. Our atmosphere also contains water vapor. In addition, Earth's atmosphere contains traces of dust particles, pollen, plant grains and other solid particles.
