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. An individual weighing 200 lbs on Earth would weigh more on a _______________ - Weight is a function of gravity






2. 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)






3. 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






4. Formed by sodium chloride






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






6. 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






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






8. The earth is believed to be about ___ billion years old






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

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






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






12. This upslope wind is called a...






13. 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






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






15. 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






16. The flow of water underground - in the vadose zone and aquifers - Subsurface water may return to the surface (as a spring or by being pumped) or eventually seep into the oceans






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






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






19. Large - dark clouds that indicate thunderstorms






20. 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...






21. 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






22. Faulting and folding






23. 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






24. 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

25. 4 terrestrials: Mercury - Venus - Mars - Earth 4 gas giants: Jupiter - Saturn - Uranus - Neptune At least 5 dwarf planets: Ceres - Pluto - Makemake - Haumea - Eris






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






27. 1 hour of time






28. Forms over land and is associated with dry air






29. Characterized by unusually warm ocean temperatures in the eastern equatorial Pacific - warm current of nutrient - poor tropical water - heated by its eastward passage in the Equatorial Current - replaces the cold - nutrient - rich surface water of th






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






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






32. This scale assigns a fixed number to 10 reference materials. Talc (1) is the softest and diamond (10) is the hardest

33. Traces of ancient life preserved in the strata as shells - footprints - and the like - Soft plant and animal tissues decompose quickly in the presence of decay bacteria - which exist wherever oxygen exists






34. Large - scale movements of the earth's lithosphere - - The theory encompasses the older concepts of continental drift (first half of 20th century) and seafloor spreading (1960s)






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






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






37. Natural chemical compounds that are the crystals that make up rocks - Each has a specific composition or narrow range of composition






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






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






40. Further caused by the elliptical orbit of the earth - Earth reaches perihelion (the point in its orbit closest to the sun) in January - and it reaches aphelion (farthest point from the sun) in July - Also depend on factors such as proximity to oceans






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






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






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






44. Sedimentary rocks containing large fragments of other rock material - e.g. Sandstone






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






46. 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






47. Continental polar (dry - cold air)






48. 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






49. Volcanoes are also found in __________ - where the denser oceanic plates are forced under continental plates; this adds massive volumes of water to the mantle - allowing magma to melt more readily and rise to the surface to form volcanoes






50. Tides may be...
