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.

3. Distance to closest stars can be calculated by measuring the _________ - a slight shift in apparent position against the background of more distant stars as the earth travels around the sun






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






5. 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

8. 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






9. Travels in an orbit that is slightly elliptical (oval) - and so the distance from the sun ranges from 91.5 to 94.5 million miles - Its daily rotation deforms the earth to a flattened spheroid - with a polar radius slightly less than the equatorial ra

11. Ancient astronomers found that eclipses occurred periodically and learned to predict them accurately - Lunar and solar






12. Weather occurs primarily due to density (temperature and moisture) differences between one location and another - These differences can occur due to the angle of the sun at any particular spot - which varies by latitude from the tropics






13. The strong temperature contrast between polar and tropical air gives rise to the ________






14. Forms over land and is associated with dry air






15. 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)






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

17. Human civilization has lasted only _____ years






18. Stars with the highest ___________ appear blue - while stars with the lowest surface temperature appear red






19. 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






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






21. Nearest galaxy - about 20 million light - years away






22. Two high waters and two low waters each day - in most locations - tides are semidiurnal






23. A region of the earth that has uniform standard time - usually referred to as the local time - divided into standard and daylight saving (or summer)






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






25. Defined by geometrically subdividing the earth's spheroid into 24 lunes (wedge - shaped sections) - bordered by meridians - each 15






26. The breakdown of rocks - soils and minerals through atmospheric chemicals or biologically produced chemicals (also known as biological weathering)






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






28. How much matter is in the object






29. A semi - closed coastal body of water with one or more rivers or streams flowing into it - and with a free connection to the open sea - Often associated with high levels of biological diversity - They are made up of brackish water - Often given names






30. Sometimes called minor planets or planetoids - Bodies






31. 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






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






33. Forms over water and is associated with wet air






34. The difference between levels of ocean water at high and low tides






35. Smooth layers of low clouds that indicate a chance of drizzle or snow






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






37. Refers to the long - term weather patterns of a large geographical area and takes into account temperature - humidity - and precipitation

43. The source of energy for evaporation is primarily through ___________






44. The movement (carrying away or displacement) of solids (sediment - soil - rock - and other particles) - usually by the agents of currents such as wind - water - or ice by downward or down - slope movement in response to gravity






45. Two feldspars (orthoclase and plagioclase) - quartz - olivine - and augite - These five minerals are silicates - built from interlocking silicon and oxygen atoms
