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 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






2. Large - dark clouds that indicate thunderstorms






3. How much matter is in the object






4. Characterized by unusually warm ocean temperatures in the same area - Atlanta tropical cyclone activity is generally enhanced during La Nina - Often follows the El Nino - especially when the latter is strong






5. Stars with the highest ___________ appear blue - while stars with the lowest surface temperature appear red






6. Faulting and folding






7. Human civilization has lasted only _____ years






8. 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






9. 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






10. Forms over land and is associated with dry air






11. 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






12. 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






13. The farther from the tropics you are positioned - the ________ the angle of the sun - This causes those locations to be cooler due to the indirect sunlight






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






15. Runoff and groundwater are stored as ________ in lakes






16. 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






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






18. The science of the atmosphere and weather






19. 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






20. Paleontology: Fossil evidence indicates the similarity of fossils on both sides of the Atlantic Ocean - Continental 'jigsaw puzzle': The outlines of the continents seem to fit together






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






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






23. Continental polar (dry - cold air)






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






25. The tendency of a moving object to stay in a straight line or a stationary object to remain in place - Without _______ - a planet would be pulled into the sun






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






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






28. At any given time - regardless of season - the Northern and Southern Hemispheres experience...






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






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






31. 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






32. Temperature - pressure - and composition






33. 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






34. Largest zone of the planet (68%); crystalline silicates - rich in magnesium - calcium - and iron; very hot and mainly solid - but local melting to magma is the source of volcanic eruptions






35. Forms over water and is associated with wet air






36. Under solar conditions - gases are undergoing _____ to heavier elements with the increase of prodigious quantities of energy






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






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






39. Giant masses of solid rock that float upon the earth's mantle - These plates move in relation to one another at one of three types of plate boundaries...






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






41. Formed by sodium chloride






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






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






44. 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






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






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






47. 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
