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






2. 186000 miles/second






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






4. Maritime tropical (wet - warm air)






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






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






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






8. Around a new or full moon - when the sun - moon - and the earth form a line - the tidal forces due to the sun reinforce those of the moon - The tide's range is at a maximum and is called a spring tide (spring as in 'to jump/leap -' not the season)






9. Air currents move clouds around the globe and cloud particles collide - grow - and fall out of the sky as ________ - Most of it falls back into the oceans or onto land - where the precipitation flows over the ground as surface runoff - portion of run






10. Travels around the earth each month - - Distance from the earth averages 237000 miles - Has rugged topography formed billions of years ago by volcanic eruptions and meteorite impacts - Mass is 1/6th that of Earth






11. 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






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






13. 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






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






15. Water transpired from plants and evaporated from the soil






16. Ancient astronomers found that eclipses occurred periodically and learned to predict them accurately - Lunar and solar






17. 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






18. Center: 3000

19. Bbreaking along flat surfaces






20. Oceans cover __ of the earth's surface






21. 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






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






23. Occur twice a year - when the tilt of the earth's axis is oriented neither from nor to the sun - causing the sun to be located vertically above a point on the equator - The name derived from the Latin aequus (equal) and nox (night) - because at the e






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






25. Method of using the present to interpret the past - Processes occurring today are observed carefully and their effects are measured - Then - geologists assume that similar effects in ancient rocks were caused by processes similar to those of the pres






26. Form when dissolved mineral solutions crystalize out of lakes and oceans






27. Cirrus - Stratus - Cumulonimbus - Altostratus






28. 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






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






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






31. The fossiliferous strata record is only the last __% of the earth's history






32. 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






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






34. 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






35. The movement of rainwater as it filters through soil and rocks into the ground - becoming groundwater






36. The runoff produced by melting snow






37. Huge systems of stars - Milky Way is estimated to have 100 billion stars arranged in a great disk






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






39. Sometimes called minor planets or planetoids - Bodies






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






41. Can thaw and melt - and the ensuing water flows overland as snowmelt






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






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






44. 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






45. Continental tropical (dry - warm air)






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






47. Smooth layers of low clouds that indicate a chance of drizzle or snow






48. 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






49. Formed from calcium carbonate - also an example of chemical sedimentary rocks - like roock salt - can contain organic or once - living matter and can record the history of that matter's formation in features such as strata - fossil evidence - and rip
