What is Earth’s atmosphere made of?
Understand the Problem
The question is asking about the composition of Earth's atmosphere, specifically requiring the user to fill in blanks related to the most abundant gases and their significance in the atmosphere.
Answer
Nitrogen, Oxygen, Argon, Carbon dioxide, dust particles.
The most abundant gas in Earth's atmosphere is nitrogen, followed by oxygen, which is needed to burn wood and fuel. The third-most abundant gas is argon. The amount of carbon dioxide in the atmosphere is very small, making up just 0.033% of the atmosphere, but it is very important because plants use it to make simple sugars. Another important gas is water vapor, which condenses around dust particles in the atmosphere to form clouds and then rain.

More Information
Earth's atmosphere, crucial for supporting life, is mostly nitrogen and oxygen with trace gases playing key roles in processes like photosynthesis and weather formation.
Tips
A common mistake is confusing the order of gas abundance. Ensure to remember nitrogen is the most abundant.
