What is the role of radiation in Earth's atmosphere?

• it's how energy is transferred from land to water

• it's how energy warms the troposphere from Earth's surface

• it's how energy reaches Earth from the sun

• it's the main way energy is transferred within Earth's atmosphere

This energy transfer method describes how the troposphere is warmed directly by Earth's surface.

• conduction

• radiation

• convection

• condensation

• respiration

• oxygen

• photosynthesis

• condensation
