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. 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






2. Volcanoes can be caused by '____________'; these so - called hotspots - as in Hawaii - can occur far from plate boundaries






3. 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

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






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






6. Sometimes called minor planets or planetoids - Bodies






7. Comprised of the crust and the rigid uppermost part of the mantle - broken up into tectonic plates (7 major and many minor) - ride on the asthenosphere






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






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






10. 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






11. The runoff produced by melting snow






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






13. Runoff and groundwater are stored as ________ in lakes






14. Bbreaking along flat surfaces






15. Distance to closest stars can be calculated by measuring the _________ - a slight shift in apparent position against the background of more distant stars as the earth travels around the sun






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






17. Center: 3000

18. 4 terrestrials: Mercury - Venus - Mars - Earth 4 gas giants: Jupiter - Saturn - Uranus - Neptune At least 5 dwarf planets: Ceres - Pluto - Makemake - Haumea - Eris






19. Human civilization has lasted only _____ years






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






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






22. 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






23. 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






24. 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






25. 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






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






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






28. Affected by factors such as weathering and impurities






29. 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






30. Formed by sodium chloride






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

32. 186000 miles/second






33. Piled in waves and indicate rain or snow






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






35. 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






36. 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






37. The outermost part of the earth's interior is made up of two layers...






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






39. Volcanoes are generally found where ________ are diverging or converging






40. Maritime tropical (wet - warm air)






41. 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






42. 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






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






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






45. The atmosphere is a __________ - and so small changes to one part of the system can grow to have large effects on the system as a whole - This makes it difficult to accurately predict weather more than a few days in advance






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






47. Igneous rock that cools beneath the earth's surface - Examples: plutons - dikes - and batholiths






48. On maps - the characteristics of an air mass are represented by two letters: The lowercase letter represents ________ - and the uppercase letter represents temperature






49. An opening - or rupture - in a planet's surface or crust - which allows hot molten rock - ash - and gases to escape from below the surface - Volcanic activity involving the extrusion of rock tends to form mountains or features like mountains over a p
