CSET Earth

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. Divided into two main types: large - low- density gas giants and smaller - rocky terrestrials - There are at least 341 identified _______ - 8 of which are in the Solar System






2. 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

3. Almost all familiar weather phenomena occur in the __________ (the lower part of the atmosphere)






4. Comprised of the crust and the rigid uppermost part of the mantle - broken up into tectonic plates (7 major and many minor) - ride on the asthenosphere






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






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






7. A major determiner of coastal climate






8. 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






9. Ancient astronomers found that eclipses occurred periodically and learned to predict them accurately - Lunar and solar






10. The rising of the earth's ocean surface caused by the tidal forces of the moon and the sun acting on the oceans






11. Large - dark clouds that indicate thunderstorms






12. 1 hour of time






13. Sedimentary rocks containing large fragments of other rock material - e.g. Sandstone






14. Volcanoes are generally found where ________ are diverging or converging






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






16. Not all runoff flows into rivers; much of it infiltrates into the ground through...






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






18. The science of the atmosphere and weather






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






20. 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






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






22. Texture is important in classifying ______ sedimentary rocks






23. Maritime tropical (wet - warm air)






24. 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






25. Some groundwater finds openings in the land surface and emerges as...






26. The degrees north or south of the equator






27. 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






28. 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






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






30. Stars with the highest ___________ appear blue - while stars with the lowest surface temperature appear red






31. Temperature - pressure - and composition






32. Forms south of the Arctic and is cold






33. 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






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

35. The runoff produced by melting snow






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






37. Faulting and folding






38. 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






39. 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






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






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






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






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






44. - 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






45. Characterized by unusually warm ocean temperatures in the eastern equatorial Pacific - warm current of nutrient - poor tropical water - heated by its eastward passage in the Equatorial Current - replaces the cold - nutrient - rich surface water of th






46. Less than 1% of the earth; this relatively thin zone (5 to 25 miles) contains the only rocks we can study - even in the deepest mines or drill holes






47. 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

49. 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
