Question

Which layer of Earth's atmosphere is most strongly affected by conditions on the sun's surface? (1 point)
• troposphere
• mesosphere
• thermosphere
• stratosphere

Answer 1

The layer of Earth's atmosphere that is most strongly affected by conditions on the sun's surface is the **thermosphere**. The thermosphere interacts with solar radiation and is influenced by solar activity, such as solar flares and solar wind, making it the most responsive to changes in the sun's conditions.
