Question
9. The flow of atmospheric water vapor is a major energy transport mechanism in Earth’s climate system. The energy flow starts with the evaporation of water from ocean and land surfaces or transpiration by vegetation transferring energy [(from air to water and land surfaces or vegetation) (from water and land surfaces or vegetation to air)].
10. Atmospheric water vapor is often carried great distances before it condenses to liquid or solid cloud particles, thereby transporting huge quantities of [(sensible)(latent)] heat energy from one place to another.
Explanation / Answer
9. Transpiration is the process through which water content is carried through the plants into the air or atmosphere by roots and stems. Thus, the correct option is from water and land surfaces or vegetation to air.
10. From the given statement, it is clear that during the transportation water vapor changes its phase. The heat released during phase change is called as latent heat. On the other hand, sensible heat is the heat produced without phase change. Thus, the correct option is latent heat.
