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






2. 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






3. Mountains blocking the path of precipitation to the desert






4. 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






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






6. Continental tropical (dry - warm air)






7. Continental polar (dry - cold air)






8. 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






9. 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






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






11. Maritime polar (wet - cold air)






12. An area of frequent earthquakes and volcanic eruptions associated with the plate boundaries surrounding the Pacific Ocean - In a 40000 km horseshoe shape - associated with a nearly continuous series of oceanic trenches - volcanic arcs - and volcanic






13. 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






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






15. 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






16. 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






17. Younger beds were originally deposited above older beds






18. 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






19. Center: 3000

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






21. Forms over water and is associated with wet air






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






23. 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






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






25. 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






26. 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)






27. Generally forms deep in the mantle as one type of rock changes into another - Due to intense pressure - can show signs of bending and distortion - Examples: schist - marble - gneiss - and slate






28. A land form that stretches above the surrounding land in a limited area - with a peak - Usually produced by the movement of lithospheric plates






29. 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






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






31. 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

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






33. 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






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. 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






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






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






38. Sometimes called minor planets or planetoids - Bodies






39. 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






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






41. 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






42. Not all runoff flows into rivers; much of it infiltrates into the ground through...






43. Water transpired from plants and evaporated from the soil






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

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