The excretory system is intended to remove any solid/fluid waste from your body, such as urine.
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.
