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. Faulting and folding






2. Center: 3000

3. 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






4. Somewhat cooler disturbances in the photosphere






5. Can thaw and melt - and the ensuing water flows overland as snowmelt






6. 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






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






8. Takes place when the moon passes between the earth and the sun - with the moon blocking the sunlight for about two minutes - A total ___________ may be seen only from a small zone on the earth






9. How much matter is in the object






10. Maritime polar (wet - cold air)






11. This upslope wind is called a...






12. 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






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






14. 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






15. 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






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






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






18. 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






19. Rising air currents take the vapor up into the atmopshere where cooler temperatures cause it to condense into ____






20. - The materials left over after the rock breaks down combine with organic material - The mineral content is determined by the parent material; thus - a soil derived from a single rock type can often be deficient in one or more minerals for good ferti






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






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






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

24. The strength of gravity in our solar system depends on both the masses of the celestial objects and the _______ between them






25. Maritime tropical (wet - warm air)






26. 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






27. 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)






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






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






30. 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






31. 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






32. Scientists theorize that massive volcanic eruptions on a global scale contributed to the earth's cooling - resulting in the onset of the...






33. Featherlike clouds that indicate fair weather






34. Method of using the present to interpret the past - Processes occurring today are observed carefully and their effects are measured - Then - geologists assume that similar effects in ancient rocks were caused by processes similar to those of the pres






35. Forms over the Tropics and is warm






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






37. Large - dark clouds that indicate thunderstorms






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






39. 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)






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






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






42. 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






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






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






45. 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
