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. Occur when two plates slip past each other - Such faults are generally moderate and are relatively shallow Example: The San Andreas Fault






2. One tidal cycle per day






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






4. 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






5. Bbreaking along flat surfaces






6. 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






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






8. Almost all familiar weather phenomena occur in the __________ (the lower part of the atmosphere)






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






10. A major determiner of coastal climate






11. Mountains blocking the path of precipitation to the desert






12. The degrees north or south of the equator






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






14. Temperature - pressure - and composition






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






16. 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






17. The evaporation of these oceans is how we get most of our __________ - and their temperature determines our climate and wind patterns






18. Less than 1% of the earth; this relatively thin zone (5 to 25 miles) contains the only rocks we can study - even in the deepest mines or drill holes






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






20. How much matter is in the object






21. 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






22. Oceans cover __ of the earth's surface






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






24. Tides may be...






25. A warm - water current that carries warm water from the Tropics to the Arctic regions of the North Atlantic Ocean - This accounts for higher temperatures and higher humidity on the Eastern Seaboard during the summer






26. The source of energy for evaporation is primarily through ___________






27. The science of the atmosphere and weather






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






29. A natural flow of water - usually freshwater - traveling toward an ocean - a lake - or another stream






30. This upslope wind is called a...






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






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

33. The stress is particularly severe in _________ - which are characterized by volcanism - metamorphism - deformation - and uplift






34. 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






35. 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






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






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






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






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






40. 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






41. Sometimes called minor planets or planetoids - Bodies






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






43. 186000 miles/second






44. Texture is important in classifying ______ sedimentary rocks






45. 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






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






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






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






49. Huge systems of stars - Milky Way is estimated to have 100 billion stars arranged in a great disk






50. 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
