.
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.

22. Land that's fit to be cultivated.

bioaccumulation
traditional subsistence agriculture
Southern Oscillation
niche
24. A usually triangular alluvial deposit at the mouth of a river.
monoculture
demographic transition model
delta
death rate (crude death rate)
25. Involves the sinking of shafts to reach underground deposits. In this type of mining - networks of tunnels are dug or blasted and humans enter these tunnels in order to manually retrieve the coal.
