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 difference between levels of ocean water at high and low tides






2. Runoff and groundwater are stored as ________ in lakes






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






4. Featherlike clouds that indicate fair weather






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






6. Defined by geometrically subdividing the earth's spheroid into 24 lunes (wedge - shaped sections) - bordered by meridians - each 15






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






8. 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






9. Can influence climate by sending tremendous volumes of dust - ash - and smoke into the atmosphere






10. The degrees north or south of the equator






11. Two types of mountains are formed - depending on how the rock reacts to the tectonic forces






12. Typically the tidal mouths of rivers and are often characterized by _____________ or silt carried in from terrestrial runoff - frequently from offshore






13. 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






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






15. The runoff produced by melting snow






16. Center: 3000

17. 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






18. Form when magma or lava cools and solidifies - Depending on the rate of cooling - can contain visible crystals - while others can appear glassy






19. Continental tropical (dry - warm air)






20. Air currents move clouds around the globe and cloud particles collide - grow - and fall out of the sky as ________ - Most of it falls back into the oceans or onto land - where the precipitation flows over the ground as surface runoff - portion of run






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






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






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






25. Oceans cover __ of the earth's surface






26. Occur when two plates pull away from each other - Such faults are generally weak and shallow Example: the Mid - Atlantic Range in the Atlantic Ocean






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






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






29. Weather occurs primarily due to density (temperature and moisture) differences between one location and another - These differences can occur due to the angle of the sun at any particular spot - which varies by latitude from the tropics






30. (or summer time zones) include an offset (typically +1 hour) for daylight saving time






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






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

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






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






35. 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






36. Tides may be...






37. 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






38. (in descending order of size) the Pacific Ocean - the Atlantic Ocean - the Indian Ocean - the Southern Ocean and the Arctic Ocean






39. 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)






40. Improved land - use practices can limit erosion by using techniques such as...






41. 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






42. Occurs when the moon sets at sunset - Then the moon is between the earth and the sun - so we see only the dark half of the moon






43. Forms south of the Arctic and is cold






44. 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






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






46. 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






47. 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.






48. 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






49. How much matter is in the object






50. 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
