Question

the amount of carbon in earths atmosphere can be observed by measuring atmosphere carbon dioxide (co₂) concentrations over time. the concentration of carbon dioxide in the air is measured in parts - per - million (ppm), which is the number of co₂ molecules per million molecules in the atmosphere. the mauna loa observatory in hawaii has been measuring atmosphere co₂ levels since the 1950s. the graph shows the amount of co₂ in the atmosphere between 2019 and 2022. seasonal changes in atmospheric co₂ concentration. source data: noaa global monitoring laboratory, measured at the mauna loa observatory. select the true statements about the atmospheric co₂ levels from 2019 to 2022. the highest concentration of atmospheric co₂ occurred in 2020. each years peak atmospheric co₂ concentration was greater than that of the previous year. atmospheric co₂ levels increased and decreased during roughly the same months each year. each year, there was more co₂ in the atmosphere in january than there was in april.

Explanation:

By observing the graph of atmospheric CO₂ concentration from 2019 - 2022, we can see that the CO₂ levels follow a seasonal pattern of increase and decrease around the same months each year. The highest concentration is not in 2020. Peak concentrations do not show a strict increase each year compared to the previous one, and in most years, there is less CO₂ in January than in April.

Answer:

Atmospheric CO₂ levels increased and decreased during roughly the same months each year.
