Greenhouse effect (= global warming) is keeping an area warm by allowing the solar radiations to pass in but preventing long wavelength heat waves to escape due to presence of radiatively active gases and glasspanes.

Water cycle or Hydrological cycle is repeated circulation of water among various components of the biosphere involving evaporation of water more from the sea and falling (precipitating) more on land and flowing back into the sea by rivers.
