What makes the following statement false? The concentration of carbon dioxide (CO2) in volcanic emissions is higher than that of water vapor (H2O) in all tectonic environments.
Understand the Problem
The question asks what makes the statement "The concentration of carbon dioxide (CO2) in volcanic emissions is higher than that of water vapor (H2O) in all tectonic environments" false. It seeks to understand why this statement is not universally true and what the true relationship between CO2 and H2O concentrations in volcanic emissions actually is.
Answer
The statement is false because water vapor often exceeds carbon dioxide concentrations in volcanic emissions.
The statement is false because, in many tectonic environments, water vapor (H2O) is the most abundant gas in volcanic emissions, exceeding the concentration of carbon dioxide (CO2).
Answer for screen readers
The statement is false because, in many tectonic environments, water vapor (H2O) is the most abundant gas in volcanic emissions, exceeding the concentration of carbon dioxide (CO2).
More Information
While volcanoes do emit CO2, contributing to the greenhouse effect, the claim that CO2 concentration always exceeds water vapor in all tectonic settings is incorrect. Water vapor is typically the dominant gas.
Tips
It is easy to assume CO2 is the most emitted gas because of the focus on it and global warming, however, the most emitted is actually water vapor.
