Hey Vanelsa. Let me help you on this one.
In this question, we will need to fill a certain word in the blank at the end of this statement. Let's take a closer look at this sentence in order for us to get a correct answer.
Both precipitation and evaporation deal with certain actions that take place within water cycle - cycle in which water circulates around the liquid, gas, and sometimes, even solid form.
In the water cycle, water turns into gas because of heat - this process is called evaporation. This gas goes up, and then, it's carried with the clouds. Once the gas form is cold enough, it will turn into water, and fall from the sky in form of the rain - this process is called precipitation.
I will be attaching image of the water cycle for you to better understand it.
Answer: Precipitation and evaporation are important components of the water cycle.
