Question

identifying steps for heating the troposphere
use the dropdown menus to complete the paragraph about how the troposphere is heated.
electromagnetic waves heat earth’s surface through
. earth’s surface warms the air directly above it through
. the warm air then rises, which transfers thermal energy through
. this air then cools and sinks, which forms a convection
current
radiation
wave
conduction

Explanation:

• Electromagnetic waves transfer energy through radiation, which is how the Sun's energy heats Earth's surface.
• Direct contact between the warm surface and the air above transfers heat via conduction.
• Rising warm air and sinking cool air creates a convection current, which transfers thermal energy through the troposphere, matching the final phrase "convection current".

Answer:

1. radiation
2. conduction
3. current
