Question

what makes up the earths atmosphere? tiny organisms that fly through the air a layer of gases that encircles our planet air created by humans to survive

Explanation:

To determine what makes up the Earth's atmosphere, we analyze each option:

• The first option refers to tiny organisms flying, which are not the main component of the atmosphere.
• The second option, "a layer of gases that encircles our planet", aligns with the scientific definition of the atmosphere (a mixture of gases like nitrogen, oxygen, etc., surrounding Earth).
• The third option is incorrect as the atmosphere is not created by humans; it has natural origins.

Answer:

B. a layer of gases that encircles our planet (Note: Assuming the options are labeled A, B, C with A being "tiny organisms that fly through the air", B being "a layer of gases that encircles our planet", and C being "air created by humans to survive")
