Which sequence lists Earth's atmosphere layers from lowest to highest?

• A. Stratosphere-Troposphere-Mesosphere-Thermosphere-Exosphere
• B. Exosphere-Thermosphere-Mesosphere-Stratosphere-Troposphere
• C. Troposphere-Stratosphere-Mesosphere-Thermosphere-Exosphere
• D. Mesosphere-Troposphere-Stratosphere-Thermosphere-Exosphere

Answer: (C)

The main idea is that Earth's atmosphere is arranged by increasing altitude, with distinct layers defined by temperature changes and what dominates each region. Starting from the surface, the order is the troposphere (where weather and life primarily reside), then the stratosphere (home to the ozone layer), followed by the mesosphere (where most meteors burn up), then the thermosphere (where space weather and satellites operate), and finally the exosphere (the outer edge gradually merging into space). This sequence aligns with the typical height ranges and the transitions between layers, marked by boundaries like the tropopause, stratopause, and mesopause. Any sequence that places the exosphere at the bottom or reorders these layers contradicts the established ascent from ground level upward.
