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






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






3. Affected by factors such as weathering and impurities






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






5. 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






6. The state change where a solid (ice or snow) changes directly to a gas (water vapor)






7. The resulting dust layer would act as a shield - blocking out much of the sun's rays - This would result in lower global temperatures and a general _____ of the earth






8. Typically the tidal mouths of rivers and are often characterized by _____________ or silt carried in from terrestrial runoff - frequently from offshore






9. Cirrus - Stratus - Cumulonimbus - Altostratus






10. 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)






11. Thought to originate in the Kuiper Belt - or associated scattered discs - which lie beyond the orbit of Neptune






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






13. Characterized by similar temperatures and moisture levels






14. 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






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






16. 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






17. 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






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






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






20. Forms south of the Arctic and is cold






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






22. The tidal force produced by the sun is ____ as large as that produced by the moon






23. 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






24. Formed by sodium chloride






25. The transformation of water from liquid to gas phases as it moves from the ground or bodies of water into the overlying atmosphere






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






27. Forms over the Tropics and is warm






28. 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






29. 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






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






31. Pulls the planets toward the sun - while their inertia keeps them moving forward in an elliptical orbit around the sun

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






33. A semi - closed coastal body of water with one or more rivers or streams flowing into it - and with a free connection to the open sea - Often associated with high levels of biological diversity - They are made up of brackish water - Often given names






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






35. 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






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






37. A continuous drill would find gas - oil - and water in that order - The three substances occur in their order of density - with the lightest substance on top and the heaviest on the bottom






38. The North Pole is in the Arctic Ocean - and thus its temperature extremes are buffered by the water - The result is that the South Pole is consistently _______ during the southern winter than the North Pole during the northern winter






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






40. The sun and oceans can also affect the weather of land - If the sun heats ocean waters for a period of time - water can evaporate - Once evaporated into the air - the moisture can spread over nearby land - thus making it cooler

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






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






43. Some precipitation falls as ____ and can accumulate as ice caps and glaciers - which can store water for thousands of years






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






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






46. The layers of sediment deposited in a quiet environment - Common sites of deposition are lakes - deltas at the mouths of rivers - beaches and sandbars along the coast - and (most important) the marine environment






47. Earth movements - The result of forces within the earth - where temperature and pressure differences lead to instability






48. Divided into two main types: large - low- density gas giants and smaller - rocky terrestrials - There are at least 341 identified _______ - 8 of which are in the Solar System






49. 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
