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






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






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






4. Believed to originate at a much greater distance from the Sun - in a cloud (the Oort cloud) consisting of debris left over from the condensation of solar nebula - Comets are thrown from the outer planets or nearby stars - or as a result of collisions






5. Classified as warm - water or cold - water currents






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






7. 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






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






9. The best determiner of climate - as it is consistently and directly correlated with temperature - other factors: Rain shadows - as well as water currents - elevation and so forth






10. The science of the atmosphere and weather






11. 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






12. 4 terrestrials: Mercury - Venus - Mars - Earth 4 gas giants: Jupiter - Saturn - Uranus - Neptune At least 5 dwarf planets: Ceres - Pluto - Makemake - Haumea - Eris






13. 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






14. Hotspot volcanoes are also found elsewhere in the Solar System - especially on...






15. Human civilization has lasted only _____ years






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






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






18. 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






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






20. Used to arrange strata in a standard order - Used to measure the amount of radioactive decay in minerals and calculate the time at which the rock formed






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






22. 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






23. Temperature - pressure - and composition






24. Mountains blocking the path of precipitation to the desert






25. Takes approx. seven and a half earth months to revolve around the sun - Takes approx. eight earth months to rotate on its axis - a day on ________ is longer than a year






26. Traces of ancient life preserved in the strata as shells - footprints - and the like - Soft plant and animal tissues decompose quickly in the presence of decay bacteria - which exist wherever oxygen exists






27. 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






28. 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






29. Condensed water vapor that falls to the earth's surface - Most precipitation occurs as rain - but also includes snow - hail - fog drip - graupel - and sleet






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






31. Defined by geometrically subdividing the earth's spheroid into 24 lunes (wedge - shaped sections) - bordered by meridians - each 15






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






33. Formed by sodium chloride






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






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






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






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






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






39. Erosion in many places is increased by human land use - Poor land - use practices include deforestation - overgrazing - unmanaged construction activity - and road building






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






41. 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
