CSET Earth

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.
1. The degrees north or south of the equator






2. Not all runoff flows into rivers; much of it infiltrates into the ground through...






3. The tendency of a moving object to stay in a straight line or a stationary object to remain in place - Without _______ - a planet would be pulled into the sun






4. Maritime polar (wet - cold air)






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






6. Piled in waves and indicate rain or snow






7. Tends to move slowly and is replenished slowly - and so it can remain in aquifers for thousands of years






8. The result of the buildup of once - living things






9. Two types of mountains are formed - depending on how the rock reacts to the tectonic forces






10. The degrees east or west of the prime meridian through Greenwich - England






11. Occur along plate boundaries






12. The center of the sun may have a temperature of millions of degrees; the visible surface - the ______ - is about 6000






13. Large - scale movements of the earth's lithosphere - - The theory encompasses the older concepts of continental drift (first half of 20th century) and seafloor spreading (1960s)






14. The spectra of distant objects display a red shift - which is interpreted as meaning that they are rapidly receding from us - This apparent expansion of the universe has given rise to the big bang theory of cosmology - in which one primeval mass expl






15. Comprised of the crust and the rigid uppermost part of the mantle - broken up into tectonic plates (7 major and many minor) - ride on the asthenosphere






16. Cause pressure differences - A hot surface heats the air above it and the air expands - lowering the air pressure and its density






17. Characterized by unusually warm ocean temperatures in the same area - Atlanta tropical cyclone activity is generally enhanced during La Nina - Often follows the El Nino - especially when the latter is strong






18. The rising of the earth's ocean surface caused by the tidal forces of the moon and the sun acting on the oceans






19. 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






20. A small Solar System body that orbits the Sun - When close enough to the sun - exhibits a visible coma (atmosphere) or a tail - both primarily from the effects of solar radiation upon the comet's nucleus - Have a variety of different orbital periods






21. Takes place when the moon passes between the earth and the sun - with the moon blocking the sunlight for about two minutes - A total ___________ may be seen only from a small zone on the earth






22. Bodies similar to the sun but immensely distant - Closest stars are 4 light - years away






23. One tidal cycle per day






24. This scale assigns a fixed number to 10 reference materials. Talc (1) is the softest and diamond (10) is the hardest

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






26. Rocks are placed into groups according to how they form...






27. The major mountains tend to occur in __________ - indicating tectonic plate boundaries and activity






28. Air currents move clouds around the globe and cloud particles collide - grow - and fall out of the sky as ________ - Most of it falls back into the oceans or onto land - where the precipitation flows over the ground as surface runoff - portion of run






29. The transformation of water from liquid to gas phases as it moves from the ground or bodies of water into the overlying atmosphere






30. 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






31. Some groundwater finds openings in the land surface and emerges as...






32. Deviates by an angle of approximately 23.5 degrees - Thus - at any given time during summer or winter - one part of the planet is more directly exposed to the rays of the sun - This exposure alternates as the earth revolves in its orbit






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






34. The earth is believed to be about ___ billion years old






35. The tidal force produced by the sun is ____ as large as that produced by the moon






36. A major determiner of coastal climate






37. Mountains blocking the path of precipitation to the desert






38. Volcanoes can be caused by '____________'; these so - called hotspots - as in Hawaii - can occur far from plate boundaries






39. The Pacific Ring of Fire has examples of volcanoes caused by ___________ coming together






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






41. Runoff and groundwater are stored as ________ in lakes






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






43. Occurs when the moon sets at sunset - Then the moon is between the earth and the sun - so we see only the dark half of the moon






44. Composed of the fragments of other types of rocks - Cover 75 to 80% of the earth's land area - Often deposited in distinct parallel layers - Weather and erosion break down other rock types into sediments - Over time - the sediments become cemented an






45. Occur when two plates pull away from each other - Such faults are generally weak and shallow Example: the Mid - Atlantic Range in the Atlantic Ocean






46. Under solar conditions - gases are undergoing _____ to heavier elements with the increase of prodigious quantities of energy






47. Method of using the present to interpret the past - Processes occurring today are observed carefully and their effects are measured - Then - geologists assume that similar effects in ancient rocks were caused by processes similar to those of the pres






48. A land form that stretches above the surrounding land in a limited area - with a peak - Usually produced by the movement of lithospheric plates






49. The flow of water underground - in the vadose zone and aquifers - Subsurface water may return to the surface (as a spring or by being pumped) or eventually seep into the oceans






50. The precipitation that is intercepted by plant foliage and eventually evaporates back to the atmosphere rather than falling to the ground
