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.

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






4. 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






5. 186000 miles/second






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






7. The North Pole is in the Arctic Ocean - and thus its temperature extremes are buffered by the water - The result is that the South Pole is consistently _______ during the southern winter than the North Pole during the northern winter






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






9. 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






10. 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






11. Solar Atmosphere is divided into the inner chromosphere with explosive prominences and the outer corona - a glowing halo visible only during a total eclipse - Constantly emitting particles as a...






12. 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






13. Sometimes called minor planets or planetoids - Bodies






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






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






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






19. Texture is important in classifying ______ sedimentary rocks






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






22. Featherlike clouds that indicate fair weather






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






24. Two high waters and two low waters each day - in most locations - tides are semidiurnal






25. Oceans cover __ of the earth's surface






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






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






28. The breakdown of rocks - soils and minerals through direct contact with atmospheric conditions such as heat - water - ice - and pressure






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. Occur when two plates push together - Such faults are strong and relatively deep - Where the strongest earthquakes occur Example: mountain building in the Himalayas and the Andes

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






34. 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

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






37. Mountains blocking the path of precipitation to the desert






38. The cold - water current that flows north to south off the _____________ keeps the West Coast fairly cool during the summer - Cold - water currents create cooler temperatures in areas that would otherwise be much warmer






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