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. Tides may be...






2. The source of energy for evaporation is primarily through ___________






3. 186000 miles/second






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






5. 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






6. Different visual appearance; when discovered - comets show a perceptible coma while asteroids do not






7. 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






8. Sometimes called minor planets or planetoids - Bodies






9. Nearest galaxy - about 20 million light - years away






10. 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






11. There are approx. _____ days between each lunar cycle






12. 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)






13. Composed of the fragments of other types of rocks - Cover 75 to 80% of the earth's land area - Often deposited in distinct parallel layers - Weather and erosion break down other rock types into sediments - Over time - the sediments become cemented an






14. 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






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






16. The runoff produced by melting snow






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






18. 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






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






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






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






22. Somewhat cooler disturbances in the photosphere






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






24. - 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






25. Tends to move slowly and is replenished slowly - and so it can remain in aquifers for thousands of years






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






27. Cirrus - Stratus - Cumulonimbus - Altostratus






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






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






30. Formed by sodium chloride






31. 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)






32. 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






33. Occurs at the instant when the sun's position in the sky is at its greatest angular distance on the other side of the equatorial plane from the observer's hemisphere - Depending on the shift of the calendar - the winter solstice occurs some time betw






34. 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






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






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






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






38. Oceans cover __ of the earth's surface






39. 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






40. 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






41. Center: 3000

42. 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






43. Mountains blocking the path of precipitation to the desert






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






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