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.

23. Drilling a hole in the ground that's below the water table to hold waste.
deep well injection
pathogens
ED50
preservation
24. The process in which soil becomes saltier and saltier until - finally - the salt prevents the growth of plants. Salinization is caused by irrigation because salts brought in with the water remain in the soil as water evaporates.
respiration
intercropping (also called strip cropping)
logistic population growth
salinization
25. Any waste that poses a danger to human health; it must be dealt with in a different way from other types of waste.
