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. Theory that the earth's continents were originally united as a supercontinent - Pangaea - Established by Alfred Wegener in the early 1900s






2. Runoff and groundwater are stored as ________ in lakes






3. 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






4. Bbreaking along flat surfaces






5. 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






6. The science of the atmosphere and weather






7. Large - dark clouds that indicate thunderstorms






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






9. 186000 miles/second






10. Somewhat cooler disturbances in the photosphere






11. 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






12. Seas - gulfs - bays - and other names






13. The result of the buildup of once - living things






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






15. Different visual appearance; when discovered - comets show a perceptible coma while asteroids do not






16. Most sediments were deposited in beds that were originally horizontal - and any tilting is due to later earth movements






17. 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






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






19. 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






20. 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






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






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






23. This upslope wind is called a...






24. Generally forms deep in the mantle as one type of rock changes into another - Due to intense pressure - can show signs of bending and distortion - Examples: schist - marble - gneiss - and slate






25. 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






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






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






28. Temperature - pressure - and composition






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






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






31. Igneous rock that forms on the earth's surface - Examples obsidian - basalt - and pumice






32. Human civilization has lasted only _____ years






33. Some water infiltrates deep into the ground and replenishes ________ - which store huge amounts of freshwater for long periods of time






34. The strong temperature contrast between polar and tropical air gives rise to the ________






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






36. Center: 3000

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






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






39. 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






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






41. Deviates by an angle of approximately 23.5 degrees - Thus - at any given time during summer or winter - one part of the planet is more directly exposed to the rays of the sun - This exposure alternates as the earth revolves in its orbit






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






43. A warm - water current that carries warm water from the Tropics to the Arctic regions of the North Atlantic Ocean - This accounts for higher temperatures and higher humidity on the Eastern Seaboard during the summer






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






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






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






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






48. 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






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






50. Some infiltration stays close to the land surface and can seep back into surface - water bodies (and the ocean) as...
