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






2. 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






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






4. One tidal cycle per day






5. 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






6. Large - dark clouds that indicate thunderstorms






7. Occur when two plates pull away from each other - Such faults are generally weak and shallow Example: the Mid - Atlantic Range in the Atlantic Ocean






8. 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...






9. 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






10. Seas - gulfs - bays - and other names






11. Loose collections of ice - dust - and small rocky particles - measuring a few kilometers or tens of kilometers across






12. 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






13. 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

14. Maritime tropical (wet - warm air)






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






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






17. 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






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






19. 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






20. The layers of sediment deposited in a quiet environment - Common sites of deposition are lakes - deltas at the mouths of rivers - beaches and sandbars along the coast - and (most important) the marine environment






21. Most sediments were deposited in beds that were originally horizontal - and any tilting is due to later earth movements






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






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






24. The process in which one type of rock changes into another






25. Tides may be...






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






27. 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






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






29. 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






30. 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






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






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






33. Typically the tidal mouths of rivers and are often characterized by _____________ or silt carried in from terrestrial runoff - frequently from offshore






34. Younger beds were originally deposited above older beds






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






36. Affected by factors such as weathering and impurities






37. The atmosphere is a __________ - and so small changes to one part of the system can grow to have large effects on the system as a whole - This makes it difficult to accurately predict weather more than a few days in advance






38. The degrees east or west of the prime meridian through Greenwich - England






39. The strong temperature contrast between polar and tropical air gives rise to the ________






40. This upslope wind is called a...






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






42. This scale assigns a fixed number to 10 reference materials. Talc (1) is the softest and diamond (10) is the hardest

43. 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...






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






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






46. The difference between levels of ocean water at high and low tides






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






48. Occur when two plates slip past each other - Such faults are generally moderate and are relatively shallow Example: The San Andreas Fault






49. Form when magma or lava cools and solidifies - Depending on the rate of cooling - can contain visible crystals - while others can appear glassy






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