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. The movement (carrying away or displacement) of solids (sediment - soil - rock - and other particles) - usually by the agents of currents such as wind - water - or ice by downward or down - slope movement in response to gravity






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






3. Water returns to the land surface at __________ than where it entered - under the force of gravity or gravity - induced pressures






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






5. The transformation of water from liquid to gas phases as it moves from the ground or bodies of water into the overlying atmosphere






6. 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...






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






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






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






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






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






12. The evaporation of these oceans is how we get most of our __________ - and their temperature determines our climate and wind patterns






13. A major determiner of coastal climate






14. The North Pole is in the Arctic Ocean - and thus its temperature extremes are buffered by the water - The result is that the South Pole is consistently _______ during the southern winter than the North Pole during the northern winter






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






16. The science of the atmosphere and weather






17. 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






18. An opening - or rupture - in a planet's surface or crust - which allows hot molten rock - ash - and gases to escape from below the surface - Volcanic activity involving the extrusion of rock tends to form mountains or features like mountains over a p






19. 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






20. 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






21. The process of chemical or physical breakdown of earth rocks - soils - and their minerals






22. Oceans cover __ of the earth's surface






23. Formed by sodium chloride






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






26. 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






27. One tidal cycle per day






28. Maritime tropical (wet - warm air)






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






30. The lateral movement of the plates is typically at speeds of ___ mm annually






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






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






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






34. 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)






35. 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






36. 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






37. 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






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. 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






40. Characterized by similar temperatures and moisture levels






41. Paleontology: Fossil evidence indicates the similarity of fossils on both sides of the Atlantic Ocean - Continental 'jigsaw puzzle': The outlines of the continents seem to fit together






42. 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
