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. One tidal cycle per day






2. 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






3. Temperature - pressure - and composition






4. Zero degrees latitude - generally has a tropical climate (warm and wet); at the extreme northern and southern latitudes (polar regions) - the climate is very cold and dry






5. Two feldspars (orthoclase and plagioclase) - quartz - olivine - and augite - These five minerals are silicates - built from interlocking silicon and oxygen atoms






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






7. 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






8. Faulting and folding






9. Oceans cover __ of the earth's surface






10. Piled in waves and indicate rain or snow






11. Gas giants Jupiter - Saturn - Uranus and Neptune have diameters far larger than Earth's and have far greater masses






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






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






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






15. A major determiner of coastal climate






16. The Pacific Ring of Fire has examples of volcanoes caused by ___________ coming together






17. 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






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






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






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






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






22. Some infiltration stays close to the land surface and can seep back into surface - water bodies (and the ocean) as...






23. Center: 3000

24. 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






25. 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)






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






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






28. 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






29. 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






30. 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






31. 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






32. Featherlike clouds that indicate fair weather






33. Continental tropical (dry - warm air)






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






35. 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.






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






37. 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






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






39. The runoff produced by melting snow






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






41. Takes approx. seven and a half earth months to revolve around the sun - Takes approx. eight earth months to rotate on its axis - a day on ________ is longer than a year






42. A region of the earth that has uniform standard time - usually referred to as the local time - divided into standard and daylight saving (or summer)






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






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






45. Some groundwater finds openings in the land surface and emerges as...






46. The movement (carrying away or displacement) of solids (sediment - soil - rock - and other particles) - usually by the agents of currents such as wind - water - or ice by downward or down - slope movement in response to gravity






47. 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






48. 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






49. Used to arrange strata in a standard order - Used to measure the amount of radioactive decay in minerals and calculate the time at which the rock formed






50. 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
