How are evaporation and transpiration similar?
Both processes occur immediately before precipitation in the water cycle.
They are both processes in which liquid water is changed into water vapor.
They both occur in the biosphere.
They both process water in its solid state.
Evaporation and transpiration are two processes included in the water cycle. The energy source that drives these processes is
the burning of fossil fuels.
the Sun.
convection within Earth's mantle.
nuclear fission.
The Sun heats the Earth's water. This warm water turns into a vapor, and rises into the atmosphere, where it cools off. What happens to this water vapor?
The water vapor evaporates and escapes into space. New water is formed by precipitation.
The water vapor only rises for a very short time, then settles back into the ocean unnoticed.
The water vapor pushes clouds out of the way as it rises. This causes overcast conditions to clear.
The water vapor condenses as it cools, then it forms clouds. It later returns to the Earth as precipitation.
