An atmosphere is the layers of gases surrounding a planet or other celestial body. ... These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.
The Earth's atmosphere protects and sustains the planet's inhabitants by providing warmth and absorbing harmful solar rays. In addition to containing the oxygen and carbon dioxide, which living things need to survive, the atmosphere traps the sun's energy and wards off many of the dangers of space.
Earth's atmosphere is a thin blanket of gases and tiny particles: together called air. We are most aware of air when it moves and creates wind.

2. Methane (CH4)
3. Simulate
4. Sparkling device
5. Lightning storm
6. brown broth rich in amino acids
7. Reducing
8. spontaneous organic compound
9. Amino acids.
Explanation:
Miller and Urey performed experiments to support the "Alexander Oparin's and J. B. S. Haldane's" hypothesis. In their experiment, they combined "Methane (CH4)," ammonia, hydrogen gas, and water in a closed system and "Simulate" it to mimic conditions on early Earth. After stimulating the system with a "Sparkling device" to mimic "Lightning Storm, " they discovered that "brown broth rich in amino acids" was produced. This suggests that early Earth had a "Reducing" atmosphere, leading to redox reactions that catalyzed the "spontaneous organic compound" synthesis of organic monomers such as "Amino acids."
