Which best describes the cycle that ensures fresh water, which is vital for carrying out metabolic processes, is available?
max2010maxim [7]

Answer: B.  evaporation, condensation, precipitation

Explanation:

The cycle that ensures that fresh water is available is called the Hydrological cycle and it involves several key processes.

As it is a cycle, none of the processes can be considered first but if any could, it would be evaporation. This is when water on the surface is heated and becomes water vapor (gas) and rises towards the atmosphere.

Condensation occurs as the water vapor rises because the further up you go, the colder it gets. These water vapor particles will thus condense and clump together to form clouds.

These clouds keep getting larger until they are too heavy to be carried by the atmosphere in which case they fall to the ground as rain the process known as precipitation.

<em>From the chart, D can be said to represent the amount of earth's surface water held by oceans while the rest (A, B, and C) can be said to be the amount of Earth's surface water that is not located in the oceans.</em>

The correct option is C.
