What is the five layer in the atmosphere?

What is the five layer in the atmosphere?

• A. Moon
• B. Earth
• C. Sun
• D. Ocean

Answer: (B)

The idea being tested is recognizing that Earth is the planet whose surrounding air is organized into five distinct layers. The atmosphere around a planet is a gaseous envelope, and for Earth these layers are troposphere, stratosphere, mesosphere, thermosphere, and exosphere—each with characteristic temperature trends as you go higher. Among the options, Earth fits because it has this layered atmospheric structure. The Moon has only a very thin exosphere, not multiple layers; the Sun is a star with its own internal and outer structures, not a planet’s atmospheric layering; the ocean is liquid water, not air. So Earth is the best answer since it is the planet whose atmosphere exhibits those five layers.
