Question

Which of the following is NOT part of the hydrologic cycle?Water on the ground may either flow on the surface of the land or travel underground or may be taken up by plants or animals.A cloud gets colder and the water molecules begin to condense to form water drops.Water drops get heavy enough that they fall from the sky.Water evaporates from the ocean surface and becomes part of a cloud.Carbon is transferred from living organisms to the atmosphere.

Answer 1

The hydrologic cycle refers to the continuous circulation of water flowinng through the atmosphere to the hidrosphere, from both to plants, etc, and changing it state (vapor/clouds, water and ice). Therefore, the first four alternatives describes processes related to this circulation and the transformation from one state to another. The last option refers only to carbon, not to water, so it's parte of the Carbon Cycle. Therefore, the correct answer is: Carbon is transferred from living organisms to the atmosphere.
