Which of the following is the lowest atmospheric layer? (1) Lithosphere (2) Stratosphere (3) Troposphere (4) Hydrosphere

1 Answer

Answer :

(3) Troposphere Explanation: The troposphere is the lowest layer of Earth's atmosphere. It starts at Earth's surface and goes up to a height of 7 to 20 km above sea level. Most of the mass (about 75- 80%) of the atmosphere is in the troposphere. Almost all weather occurs within this layer.
