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






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






3. Take up about 1/3 of the earth's land surface - many are formed by rain shadows - Usually have a large diurnal (day) and seasonal temperature range - with high daytime temperatures






4. 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






5. 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






6. The source of energy for evaporation is primarily through ___________






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






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






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






10. Condensed water vapor that falls to the earth's surface - Most precipitation occurs as rain - but also includes snow - hail - fog drip - graupel - and sleet






11. Characterized by similar temperatures and moisture levels






12. Occur when two plates push together - Such faults are strong and relatively deep - Where the strongest earthquakes occur Example: mountain building in the Himalayas and the Andes






13. Formed by sodium chloride






14. Mountains blocking the path of precipitation to the desert






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






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






17. Can influence climate by sending tremendous volumes of dust - ash - and smoke into the atmosphere






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






19. Texture is important in classifying ______ sedimentary rocks






20. Runoff and groundwater are stored as ________ in lakes






21. Younger beds were originally deposited above older beds






22. A huge ball of incandescent gases - Its mass is more than 300000 times that of the earth - Principal constituents are the lightest elements - hydrogen and helium






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






24. After the moon has waxed through crescent - quarter - and gibbous phases - a ________ appears - At that time - the moon rises at sunset - and we see all of its illuminated side - Then the phase wanes gradually to another new moon






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






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






27. 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






28. 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






29. 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






30. Large - dark clouds that indicate thunderstorms






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






32. The atmosphere is a __________ - and so small changes to one part of the system can grow to have large effects on the system as a whole - This makes it difficult to accurately predict weather more than a few days in advance






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






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






35. Somewhat cooler disturbances in the photosphere






36. Center: 3000

37. Sometimes called minor planets or planetoids - Bodies






38. 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






39. Featherlike clouds that indicate fair weather






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






41. Volcanoes can be caused by '____________'; these so - called hotspots - as in Hawaii - can occur far from plate boundaries






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






43. Cirrus - Stratus - Cumulonimbus - Altostratus






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

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






46. The degrees east or west of the prime meridian through Greenwich - England






47. Common: wind - clouds - rain - snow - fog - dust storms - Less common: natural disasters such as tornadoes - hurricanes - and ice storms






48. The process of chemical or physical breakdown of earth rocks - soils - and their minerals






49. Test the item against materials of known hardness; for example - use your fingernail or the graphite in a pencil to attempt to scratch the items. This process should result in assigning a relative hardness to the unknown items.






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