Which layer of the atmosphere is closest to the Earth's surface?

Correct answer: Troposphere

Explanation: ✅ Correct Answer: C) Troposphere 📚 Explanation: The troposphere extends from the Earth's surface up to an average height of about 13 km and contains nearly all the atmosphere's water vapor. Almost all weather phenomena, including rain, snow, and storms, take place within this layer. As altitude increases in the troposphere, the temperature generally decreases at a predictable rate.
