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






2. Oceans cover __ of the earth's surface






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






4. Mountains blocking the path of precipitation to the desert






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






6. Sometimes called minor planets or planetoids - Bodies






7. Two feldspars (orthoclase and plagioclase) - quartz - olivine - and augite - These five minerals are silicates - built from interlocking silicon and oxygen atoms






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






9. The science of the atmosphere and weather






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. 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






12. Pulls the planets toward the sun - while their inertia keeps them moving forward in an elliptical orbit around the sun

13. Smooth layers of low clouds that indicate a chance of drizzle or snow






14. Temperature - pressure - and composition






15. 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






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






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






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






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






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






21. 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






22. The stress is particularly severe in _________ - which are characterized by volcanism - metamorphism - deformation - and uplift






23. A major determiner of coastal climate






24. 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






25. 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






26. The source of energy for evaporation is primarily through ___________






27. Piled in waves and indicate rain or snow






28. Result from the earth's axis being tilted to its orbital plane - NOT the result of the variation in the earth's distance to the sun (Because of its elliptical orbit - the earth as a whole is slightly warmer when away from the sun; this is because the






29. Igneous rock that cools beneath the earth's surface - Examples: plutons - dikes - and batholiths






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






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






32. 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






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






34. 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






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






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






37. 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






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






39. 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






40. 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






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






42. The strength of gravity in our solar system depends on both the masses of the celestial objects and the _______ between them






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






44. One tidal cycle per day






45. The degrees north or south of the equator






46. 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
