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:

• "Tiny organisms that fly through the air" describes airborne organisms (like insects or microbes) but not the atmosphere itself.
• "A layer of gases that encircles our planet" matches the scientific definition of the atmosphere, which is a gaseous envelope surrounding Earth.
• "Air created by humans to survive" is incorrect, as the atmosphere exists naturally and is not human - created for survival in this way.

Answer:

B. a layer of gases that encircles our planet (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")
