Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Also called that water cycle - this process describes the cycling of water throughout the environment. The stages of this cycle are evaporation - condensation - transportation - precipitation - infiltration and percolation - and run off.
