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. 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)






2. Somewhat cooler disturbances in the photosphere






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






4. The best determiner of climate - as it is consistently and directly correlated with temperature - other factors: Rain shadows - as well as water currents - elevation and so forth






5. Featherlike clouds that indicate fair weather






6. Evaporation often implicitly includes ___________ from plants - although together they are specifically referred to as evapotranspiration






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

9. 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

11. 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

15. Form when dissolved mineral solutions crystalize out of lakes and oceans






16. Zero degrees latitude - generally has a tropical climate (warm and wet); at the extreme northern and southern latitudes (polar regions) - the climate is very cold and dry






17. Rising air currents take the vapor up into the atmopshere where cooler temperatures cause it to condense into ____






18. 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






19. Formed by sodium chloride






20. Occurs at the instant when the sun's position in the sky is at its greatest angular distance on the other side of the equatorial plane from the observer's hemisphere - Depending on the shift of the calendar - the winter solstice occurs some time betw






21. Texture is important in classifying ______ sedimentary rocks






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






23. Bbreaking along flat surfaces






24. 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






25. Faulting and folding






26. Seas - gulfs - bays - and other names






27. Continental tropical (dry - warm air)






28. The runoff produced by melting snow






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






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






31. 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






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






33. Maritime tropical (wet - warm air)






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

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






38. Due to a combination of differential heating and geometry - hen the sun rises - it is the tops of the mountain peaks which receive first light - and as the day progresses - the mountain slopes take on a greater heat load than the valleys - This resul






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






40. Formed from calcium carbonate - also an example of chemical sedimentary rocks - like roock salt - can contain organic or once - living matter and can record the history of that matter's formation in features such as strata - fossil evidence - and rip






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