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 strength of gravity in our solar system depends on both the masses of the celestial objects and the _______ between them






2. 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






3. 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






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






5. The runoff produced by melting snow






6. 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






7. Volcanoes are also found in __________ - where the denser oceanic plates are forced under continental plates; this adds massive volumes of water to the mantle - allowing magma to melt more readily and rise to the surface to form volcanoes






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






9. One tidal cycle per day






10. Affected by factors such as weathering and impurities






11. 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)






12. 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






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






14. Takes approx. seven and a half earth months to revolve around the sun - Takes approx. eight earth months to rotate on its axis - a day on ________ is longer than a year






15. This upslope wind is called a...






16. 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






17. Pulls the planets toward the sun - while their inertia keeps them moving forward in an elliptical orbit around the sun

18. Both gravity and inertia work together to keep planets in orbit around the sun - Inertia makes a planet travel in a straight line






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






20. 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






21. The motive force behind land breezes and sea/lake breezes - also known as on - or off - shore winds - Land absorbs and radiates heat faster than water - but water releases heat over a longer period of time






22. 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






23. 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






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






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






26. Maritime tropical (wet - warm air)






27. Temperature - pressure - and composition






28. Divided into two main types: large - low- density gas giants and smaller - rocky terrestrials - There are at least 341 identified _______ - 8 of which are in the Solar System






29. Spiral - elliptical - and irregular form are speckled throughout the visible universe - Largest telescope has detected galaxies to its limit of several billion light - years






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






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






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






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






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






35. 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






36. Somewhat cooler disturbances in the photosphere






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






38. The sun and oceans can also affect the weather of land - If the sun heats ocean waters for a period of time - water can evaporate - Once evaporated into the air - the moisture can spread over nearby land - thus making it cooler

39. Characterized by similar temperatures and moisture levels






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

41. Solar Atmosphere is divided into the inner chromosphere with explosive prominences and the outer corona - a glowing halo visible only during a total eclipse - Constantly emitting particles as a...






42. Faulting and folding






43. Water transpired from plants and evaporated from the soil






44. 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






45. Precipitation - Canopy interception - Snowmelt - Runoff - Percolation - Subsurface flow- Evaporation - Sublimation - Condensation






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






47. Featherlike clouds that indicate fair weather






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