Here's how to figure out which gases are present in the atmosphere at greater than 1% concentration:

* Nitrogen (N2): This is the most abundant gas in the atmosphere, making up about 78%.

* Oxygen (O2): The second most abundant gas, comprising about 21%.

* Argon (Ar): Found in about 0.93%.

* Carbon Dioxide (CO2): While important, its concentration is currently around 0.04%.

Therefore, the gases found in the atmosphere with a concentration greater than 1% are:

* Nitrogen (N2)

* Oxygen (O2)

* Argon (Ar)
