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 transformation of water vapor to liquid water droplets in the air - producing clouds and fog






2. Spiral - elliptical - and irregular form are speckled throughout the visible universe - Largest telescope has detected galaxies to its limit of several billion light - years






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






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






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






6. The farther from the tropics you are positioned - the ________ the angle of the sun - This causes those locations to be cooler due to the indirect sunlight






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






8. The breakdown of rocks - soils and minerals through direct contact with atmospheric conditions such as heat - water - ice - and pressure






9. 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






10. 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






11. At any given time - regardless of season - the Northern and Southern Hemispheres experience...






12. Characterized by unusually warm ocean temperatures in the same area - Atlanta tropical cyclone activity is generally enhanced during La Nina - Often follows the El Nino - especially when the latter is strong






13. 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






14. Somewhat cooler disturbances in the photosphere






15. Maritime tropical (wet - warm air)






16. 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






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






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


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






20. Occur along plate boundaries






21. Seas - gulfs - bays - and other names






22. This upslope wind is called a...






23. On maps - the characteristics of an air mass are represented by two letters: The lowercase letter represents ________ - and the uppercase letter represents temperature






24. A major determiner of coastal climate






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






26. The tidal force produced by the sun is ____ as large as that produced by the moon






27. Deviates by an angle of approximately 23.5 degrees - Thus - at any given time during summer or winter - one part of the planet is more directly exposed to the rays of the sun - This exposure alternates as the earth revolves in its orbit






28. Bbreaking along flat surfaces






29. 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






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






31. 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






32. Sometimes called minor planets or planetoids - Bodies






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






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






35. Human civilization has lasted only _____ years






36. Theory that the earth's continents were originally united as a supercontinent - Pangaea - Established by Alfred Wegener in the early 1900s






37. Volcanoes are also found in __________ - where the denser oceanic plates are forced under continental plates; this adds massive volumes of water to the mantle - allowing magma to melt more readily and rise to the surface to form volcanoes






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






39. 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






40. There are approx. _____ days between each lunar cycle






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






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


43. Forms over the Tropics and is warm






44. 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






45. Forms over water and is associated with wet air






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