  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • 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. A usually triangular alluvial deposit at the mouth of a river.

2. A severe tropical cyclone originating in the equatorial regions of the Atlantic Ocean or Caribbean Sea or eastern regions of the Pacific Ocean - traveling north - northwest - or northeast from its point of origin - and usually involving heavy rains.

3. Any substance that has an LD50 - of 50 mg or less per kg of body weight.

4. The maximum population size that can be supported by the available resources in a region.

5. The low-rainfall region that exists on the leeward (downwind) side of a mountain range. This rain shadow is the result of the mountain range's causing precipitation on the windward side.

6. Pollutants that are released directly into the lower atmosphere.

7. In fishing - the use of long lines that have baited hooks and will be taken by numerous aquatic organisms.

8. Organisms that reproduce later in life - produce fewer offspring - and devote significant time and energy to the nurturing of their offspring.

9. The amount of the Earth's surface that's necessary to supply the needs of - and dispose of the waste from a particular population.

10. Any process that breaks rock down into smaller pieces without changing the chemistry of the rock; typically wind and water.

11. The number of live births per 1 -000 members of the population in a year.

12. When the size of an organism's natural habitat is reduced - or when development occurs that isolates a habitat.

13. An organism that is capable of converting radiant energy or chemical energy into carbohydrates.

14. An influential theory that concerns the long-term rate of conventional oil (and other fossil fuel) extraction and depletion. It predicts that future world oil production will soon reach a peak and then rapidly decline.

15. The accumulation of a substance - such as a toxic chemical - in various tissues of a living organism.

16. A cooling of the ocean surface off the western coast of South America - occurring periodically every 4 to 12 years and affecting Pacific and other weather patterns.

17. Power generated using water.

18. The form petroleum takes when in the ground.

19. Is the practice of planting bands of different crops across a hillside.

20. When populations are well below the size dictated by the carrying capacity of the region they live in - they will grow exponentially - but as they approach the carrying capacity - their growth rate will decrease and the size of the population will ev

21. A system of vertical and horizontal air circulation predominating in tropical and subtropical regions and creating major weather patterns.

22. The capacity to do work.

23. Air currents caused by the vertical movement of air due to atmospheric heating and cooling.

24. The second-purest form of coal.

25. The point at which 50 percent of the test organisms die from a toxin.

26. The development and introduction of new varieties of (mainly) wheat and rice that has increased yields per acre dramatically in countries since the 1960s.

27. A soil horizon; the layer below the O layer is called the A layer. The A layer is formed of weathered rock - with some organic material; often referred to as topsoil.

28. Refers to resources - such as plants and animals - which can be regenerated if harvested at sustainable yields.

29. Open or forested areas built at the outer edge of a city.

30. The number of children a couple must have in order to replace themselves in a population.

31. Involves the removal of the Earth's surface all the way down to the level of the mineral seam.

32. When a species occupies a smaller niche than it would in the absence of competition.

33. A tank filled with aerobic bacteria that's used to treat sewage.

34. The conversion of atmospheric nitrogen into compounds - such as ammonia - by natural agencies or various industrial processes.

35. Radioactive wastes that produce high levels of ionizing radiation.

36. When the signs and symptoms of an illness can be attributed to a specific infectious organism that resides in the building.

37. An influential theory that concerns the long - term rate of conventional oil (and other fossil fuel) extraction and depletion. It predicts that future world oil production will soon reach a peak and then rapidly decline.

38. Land that's fit to be cultivated.

39. The finest soil - made up of particles that are less than 0.002 mm in diameter.

40. The energy of motion.

41. A high-speed - meandering wind current - generally moving from a westerly direction at speeds often exceeding 400 km (250 miles) per hour at altitudes of 15 to 25 km (10 to 15 miles).

42. The process in which plants absorb ammonium (NH3) - ammonia ions (NH4+) - and nitrate ions (NO3) through their roots.

43. Non-moving sources of pollution - such as factories.

44. Countries that have a renewable annual water supply of about 1 -000 -2 -000 m3 per person.

45. A nuclear reaction in which an atomic nucleus - especially a heavy nucleus such as an isotope of uranium - splits into fragments - usually two fragments of comparable mass - releasing from 100 million to several hundred million electron volts of ener

46. The result of vibrations (often due to plate movements) deep in the Earth that release energy. They often occur as two plates slide past one another at a transform boundary.

47. An erosion-resistant marine ridge or mound consisting chiefly of compacted coral together with algal material and biochemically deposited magnesium and calcium carbonates.

48. Resources that are often formed by very slow geologic processes - so we consider them incapable of being regenerated within the realm of human existence.

49. A stable - mature community in a successive series that has reached equilibrium after having evolved through stages and adapted to its environment.

50. The uppermost horizon of soil. It is primarily made up of organic material - including waste from organisms - the bodies of decomposing organisms - and live organisms.
