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 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






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






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






4. Comprises one global - interconnected body of salt water often (though generally recognized as several separate oceans) - A continuous body of water with relatively free interchange among its parts






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






6. Maritime polar (wet - cold air)






7. (or summer time zones) include an offset (typically +1 hour) for daylight saving time






8. Improved land - use practices can limit erosion by using techniques such as...






9. 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






10. Gas giants Jupiter - Saturn - Uranus and Neptune have diameters far larger than Earth's and have far greater masses






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






12. Texture is important in classifying ______ sedimentary rocks






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






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






15. The stress is particularly severe in _________ - which are characterized by volcanism - metamorphism - deformation - and uplift






16. Loose collections of ice - dust - and small rocky particles - measuring a few kilometers or tens of kilometers across






17. Oceans cover __ of the earth's surface






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






19. 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






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. - The materials left over after the rock breaks down combine with organic material - The mineral content is determined by the parent material; thus - a soil derived from a single rock type can often be deficient in one or more minerals for good ferti






22. Erosion in many places is increased by human land use - Poor land - use practices include deforestation - overgrazing - unmanaged construction activity - and road building






23. 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






24. 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






25. Classified as warm - water or cold - water currents






26. Sometimes called minor planets or planetoids - Bodies






27. Runoff and groundwater are stored as ________ in lakes






28. A natural flow of water - usually freshwater - traveling toward an ocean - a lake - or another stream






29. The science that describes and interprets the earth Fields: - Geomorphology (land forms) - Petrology (rocks) - Stratigraphy (layered rocks) - Paleontology (fossils)






30. Featherlike clouds that indicate fair weather






31. The degrees north or south of the equator






32. 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






33. One tidal cycle per day






34. Seas - gulfs - bays - and other names






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






36. The science of the atmosphere and weather






37. 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






38. Hotspot volcanoes are also found elsewhere in the Solar System - especially on...






39. Somewhat cooler disturbances in the photosphere






40. 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






41. Further caused by the elliptical orbit of the earth - Earth reaches perihelion (the point in its orbit closest to the sun) in January - and it reaches aphelion (farthest point from the sun) in July - Also depend on factors such as proximity to oceans






42. The lateral movement of the plates is typically at speeds of ___ mm annually
