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






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






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






4. 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






5. Human civilization has lasted only _____ years






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






7. 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)






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






9. Texture is important in classifying ______ sedimentary rocks






10. 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






11. Rocks are placed into groups according to how they form...






12. 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






13. The runoff produced by melting snow






14. The tendency of a moving object to stay in a straight line or a stationary object to remain in place - Without _______ - a planet would be pulled into the sun






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






16. 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)






17. The sun is not at the center of the disk - but out toward the perimeter - and is revolving around the ________






18. Cause pressure differences - A hot surface heats the air above it and the air expands - lowering the air pressure and its density






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






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






21. The resulting dust layer would act as a shield - blocking out much of the sun's rays - This would result in lower global temperatures and a general _____ of the earth






22. Forms south of the Arctic and is cold






23. 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






24. Common: wind - clouds - rain - snow - fog - dust storms - Less common: natural disasters such as tornadoes - hurricanes - and ice storms






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






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






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






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






30. The Pacific Ring of Fire has examples of volcanoes caused by ___________ coming together






31. Volcanoes can be caused by '____________'; these so - called hotspots - as in Hawaii - can occur far from plate boundaries






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






33. Under solar conditions - gases are undergoing _____ to heavier elements with the increase of prodigious quantities of energy






34. The fossiliferous strata record is only the last __% of the earth's history






35. 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






36. 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...






37. Distance to closest stars can be calculated by measuring the _________ - a slight shift in apparent position against the background of more distant stars as the earth travels around the sun






38. Bbreaking along flat surfaces






39. A semi - closed coastal body of water with one or more rivers or streams flowing into it - and with a free connection to the open sea - Often associated with high levels of biological diversity - They are made up of brackish water - Often given names






40. How much matter is in the object






41. 186000 miles/second






42. 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






43. 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






44. Igneous rock that forms on the earth's surface - Examples obsidian - basalt - and pumice






45. Smooth layers of low clouds that indicate a chance of drizzle or snow






46. 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






47. Giant masses of solid rock that float upon the earth's mantle - These plates move in relation to one another at one of three types of plate boundaries...






48. A small Solar System body that orbits the Sun - When close enough to the sun - exhibits a visible coma (atmosphere) or a tail - both primarily from the effects of solar radiation upon the comet's nucleus - Have a variety of different orbital periods
