Subjects : cset, science
Instructions:
  • 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.

9. Water returns to the land surface at __________ than where it entered - under the force of gravity or gravity - induced pressures






10. Seasons are marked by changes in the amount of sunlight - which in turn often cause cycles of dormancy in plants and hibernation in animals - These effects vary with latitude and with proximity to bodies of water

18. The variety of ways by which water moves across the land - This includes both surface runoff and channel runoff - As it flows - the water may percolate into the ground - evaporate into the air - become stored in lakes or reservoirs - or be extracted






19. Different visual appearance; when discovered - comets show a perceptible coma while asteroids do not






20. Some isolated mountains were produced by volcanoes - including many apparently ________ that reach a great height above the ocean floor






21. Earth movements - The result of forces within the earth - where temperature and pressure differences lead to instability






22. Volcanoes can also form where there is stretching and thinning of the...

23. Characterized by unusually warm ocean temperatures in the eastern equatorial Pacific - warm current of nutrient - poor tropical water - heated by its eastward passage in the Equatorial Current - replaces the cold - nutrient - rich surface water of th






24. Oceans cover __ of the earth's surface






25. The movement of rainwater as it filters through soil and rocks into the ground - becoming groundwater






26. Some precipitation falls as ____ and can accumulate as ice caps and glaciers - which can store water for thousands of years






27. The process in which one type of rock changes into another






28. Forms over the Tropics and is warm

35. Thought to originate in the Kuiper Belt - or associated scattered discs - which lie beyond the orbit of Neptune






36. There are approx. _____ days between each lunar cycle






37. A warm - water current that carries warm water from the Tropics to the Arctic regions of the North Atlantic Ocean - This accounts for higher temperatures and higher humidity on the Eastern Seaboard during the summer






38. A ______________ - such as the Mid - Atlantic Ridge - has examples of volcanoes caused by divergent tectonic plates pulling apart






39. The outermost part of the earth's interior is made up of two layers...

41. After the moon has waxed through crescent - quarter - and gibbous phases - a ________ appears - At that time - the moon rises at sunset - and we see all of its illuminated side - Then the phase wanes gradually to another new moon






42. The atmosphere is a __________ - and so small changes to one part of the system can grow to have large effects on the system as a whole - This makes it difficult to accurately predict weather more than a few days in advance






43. Cirrus - Stratus - Cumulonimbus - Altostratus






44. Believed to originate at a much greater distance from the Sun - in a cloud (the Oort cloud) consisting of debris left over from the condensation of solar nebula - Comets are thrown from the outer planets or nearby stars - or as a result of collisions






45. Loose collections of ice - dust - and small rocky particles - measuring a few kilometers or tens of kilometers across
