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. On maps - the characteristics of an air mass are represented by two letters: The lowercase letter represents ________ - and the uppercase letter represents temperature






2. Scientists theorize that massive volcanic eruptions on a global scale contributed to the earth's cooling - resulting in the onset of the...






3. Around a new or full moon - when the sun - moon - and the earth form a line - the tidal forces due to the sun reinforce those of the moon - The tide's range is at a maximum and is called a spring tide (spring as in 'to jump/leap -' not the season)






4. Darkens the moon as the earth passes between it and the sun - casting a shadow on the moon - may be seen from anywhere the moon is visible - about half of the earth






5. 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






6. Formed by sodium chloride






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






8. 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






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






10. 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






11. Piled in waves and indicate rain or snow






12. Center: 3000

13. Sun heats water in the oceans - Water evaporates as vapor into the air - Ice and snow can sublimate directly into water vapor...- Over time - the water reenters the ocean - where the water cycle started






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






15. Traces of ancient life preserved in the strata as shells - footprints - and the like - Soft plant and animal tissues decompose quickly in the presence of decay bacteria - which exist wherever oxygen exists






16. The transformation of water vapor to liquid water droplets in the air - producing clouds and fog






17. An individual weighing 200 lbs on Earth would weigh more on a _______________ - Weight is a function of gravity






18. At any given time - regardless of season - the Northern and Southern Hemispheres experience...






19. Faulting and folding






20. Maritime polar (wet - cold air)






21. 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






22. Officially defined as sustained sea surface temperature anomalies of magnitude greater than 0.5






23. The sun is not at the center of the disk - but out toward the perimeter - and is revolving around the ________






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






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






26. Cirrus - Stratus - Cumulonimbus - Altostratus






27. Igneous rock that cools beneath the earth's surface - Examples: plutons - dikes - and batholiths






28. Occur when two plates push together - Such faults are strong and relatively deep - Where the strongest earthquakes occur Example: mountain building in the Himalayas and the Andes






29. Less than 1% of the earth; this relatively thin zone (5 to 25 miles) contains the only rocks we can study - even in the deepest mines or drill holes






30. The fossiliferous strata record is only the last __% of the earth's history






31. 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






32. 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






33. Result from the earth's axis being tilted to its orbital plane - NOT the result of the variation in the earth's distance to the sun (Because of its elliptical orbit - the earth as a whole is slightly warmer when away from the sun; this is because the






34. 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






35. Seas - gulfs - bays - and other names
