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. Temperature - pressure - and composition






2. Seasons are marked by changes in the amount of sunlight - which in turn often cause cycles of dormancy in plants and hibernation in animals - These effects vary with latitude and with proximity to bodies of water






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






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






5. 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






6. This upslope wind is called a...






7. 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






8. Bodies similar to the sun but immensely distant - Closest stars are 4 light - years away






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






10. 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






11. Some infiltration stays close to the land surface and can seep back into surface - water bodies (and the ocean) as...






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






13. - 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






14. Travels around the earth each month - - Distance from the earth averages 237000 miles - Has rugged topography formed billions of years ago by volcanic eruptions and meteorite impacts - Mass is 1/6th that of Earth






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






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






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






18. 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






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






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






21. Characterized by similar temperatures and moisture levels






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






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






24. 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






25. 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






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






27. Occurs when the moon sets at sunset - Then the moon is between the earth and the sun - so we see only the dark half of the moon






28. 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






29. Featherlike clouds that indicate fair weather






30. 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

31. Method of using the present to interpret the past - Processes occurring today are observed carefully and their effects are measured - Then - geologists assume that similar effects in ancient rocks were caused by processes similar to those of the pres






32. 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)






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






34. The science that describes and interprets the earth Fields: - Geomorphology (land forms) - Petrology (rocks) - Stratigraphy (layered rocks) - Paleontology (fossils)






35. 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






36. 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






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






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






39. Forms over water and is associated with wet air






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






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






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






43. 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






44. Darkens the moon as the earth passes between it and the sun - casting a shadow on the moon - may be seen from anywhere the moon is visible - about half of the earth






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