Question

select the statement(s) that are true about carbon. carbon dioxide absorbs solar radiation. carbon dioxide is toxic and therefore must be converted into a safer form. carbon atoms are essential to all life on earth. the ocean stores more carbon than the atmosphere. the ocean releases more carbon than it stores.

Explanation:

• Carbon dioxide absorbs infrared radiation, not solar radiation directly. So the first statement is false.
• Carbon dioxide is not toxic in normal - concentrations; it is a natural part of the atmosphere and is used by plants in photosynthesis. So the second statement is false.
• Carbon is a key element in organic compounds, which are essential for all life on Earth. So the third statement is true.
• The ocean is a major carbon sink and stores more carbon than the atmosphere. So the fourth statement is true.
• The ocean stores more carbon than it releases as part of the carbon cycle. So the fifth statement is false.

Answer:

Carbon atoms are essential to all life on Earth.
The ocean stores more carbon than the atmosphere.
