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 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






2. Affected by factors such as weathering and impurities






3. 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






4. 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






5. Volcanoes can also form where there is stretching and thinning of the...

6. Water transpired from plants and evaporated from the soil






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






8. Tides may be...






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

10. Forms over the Tropics and is warm






11. A small Solar System body that orbits the Sun - When close enough to the sun - exhibits a visible coma (atmosphere) or a tail - both primarily from the effects of solar radiation upon the comet's nucleus - Have a variety of different orbital periods






12. 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






13. Occur when two plates slip past each other - Such faults are generally moderate and are relatively shallow Example: The San Andreas Fault






14. The cold - water current that flows north to south off the _____________ keeps the West Coast fairly cool during the summer - Cold - water currents create cooler temperatures in areas that would otherwise be much warmer






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






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






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






18. 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






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






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






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






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






23. 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






24. Maritime tropical (wet - warm air)






25. 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)






26. Featherlike clouds that indicate fair weather






27. 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






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






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






30. Formed by sodium chloride






31. Sedimentary rocks containing large fragments of other rock material - e.g. Sandstone






32. Volcanoes are generally found where ________ are diverging or converging






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






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






35. This upslope wind is called a...






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






37. The breakdown of rocks - soils and minerals through direct contact with atmospheric conditions such as heat - water - ice - and pressure






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






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






40. An opening - or rupture - in a planet's surface or crust - which allows hot molten rock - ash - and gases to escape from below the surface - Volcanic activity involving the extrusion of rock tends to form mountains or features like mountains over a p






41. Oceans cover __ of the earth's surface






42. 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






43. Almost all familiar weather phenomena occur in the __________ (the lower part of the atmosphere)






44. Somewhat cooler disturbances in the photosphere






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






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






47. Runoff and groundwater are stored as ________ in lakes






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






49. 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






50. Center: 3000
