In what form is carbon found in the atmosphere?
[tex]$CO _2$[/tex]
[tex]$C _6 H _{12} O _6$[/tex]
[tex]$H _2 O$[/tex]
ATP
Answer (2)
Carbon is primarily found in the atmosphere in the form of carbon dioxide ( C O 2 ). Other options provided, such as glucose ( C 6 H 12 O 6 ), water ( H 2 O ), and ATP, either do not contain carbon in a gaseous state or are not atmospheric components. Therefore, the correct answer is C O 2 .
;
Analyze each option to determine if it contains carbon and if it is commonly found in the atmosphere.
C O 2 (carbon dioxide) is a well-known gas composed of carbon and oxygen and a significant component of the Earth's atmosphere.
C 6 H 12 O 6 (glucose), H 2 O (water), and ATP (adenosine triphosphate) are not primary components of the atmosphere.
Carbon is found in the atmosphere in the form of C O 2 .
Explanation
Understanding the Question The question asks us to identify the form in which carbon is found in the atmosphere from the given options. We need to consider the chemical composition of each option and determine which one is a common atmospheric component containing carbon.
Analyzing the Options Let's analyze each option:
C O 2 (Carbon Dioxide): A well-known gas composed of carbon and oxygen. It's a significant component of the Earth's atmosphere.
C 6 H 12 O 6 (Glucose): A sugar molecule made of carbon, hydrogen, and oxygen. While it exists on Earth, it's not a primary component of the atmosphere.
H 2 O (Water): A compound of hydrogen and oxygen. Water vapor is present in the atmosphere, but it doesn't contain carbon.
ATP (Adenosine Triphosphate): A complex organic molecule that provides energy for cells. It contains carbon, but it is not typically found as a free-floating molecule in the atmosphere.
Determining the Answer Based on the analysis, carbon dioxide ( C O 2 ) is the most common form of carbon found in the atmosphere. It is a major component of the air we breathe and is essential for processes like photosynthesis.
Examples
Understanding the forms of carbon in the atmosphere is crucial for studying climate change and the carbon cycle. For example, measuring C O 2 levels helps scientists track greenhouse gas emissions and their impact on global warming. Similarly, understanding how carbon moves between the atmosphere, oceans, and land is essential for developing strategies to mitigate climate change and promote sustainable practices.
