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






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






3. Composed of the fragments of other types of rocks - Cover 75 to 80% of the earth's land area - Often deposited in distinct parallel layers - Weather and erosion break down other rock types into sediments - Over time - the sediments become cemented an






4. 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






5. Believed to originate at a much greater distance from the Sun - in a cloud (the Oort cloud) consisting of debris left over from the condensation of solar nebula - Comets are thrown from the outer planets or nearby stars - or as a result of collisions






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






7. Faulting and folding






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






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






10. 1 hour of time






11. Solar Atmosphere is divided into the inner chromosphere with explosive prominences and the outer corona - a glowing halo visible only during a total eclipse - Constantly emitting particles as a...






12. The earth is believed to be about ___ billion years old






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






14. Temperature - pressure - and composition






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






16. Maritime polar (wet - cold air)






17. Tides may be...






18. A huge ball of incandescent gases - Its mass is more than 300000 times that of the earth - Principal constituents are the lightest elements - hydrogen and helium






19. 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






20. Continental tropical (dry - warm air)






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






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






23. 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






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






25. The state change where a solid (ice or snow) changes directly to a gas (water vapor)






26. (in descending order of size) the Pacific Ocean - the Atlantic Ocean - the Indian Ocean - the Southern Ocean and the Arctic Ocean






27. 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






28. After the moon has waxed through crescent - quarter - and gibbous phases - a ________ appears - At that time - the moon rises at sunset - and we see all of its illuminated side - Then the phase wanes gradually to another new moon






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






30. Refers to the long - term weather patterns of a large geographical area and takes into account temperature - humidity - and precipitation






31. 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






32. 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






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






34. 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...






35. Occur when two plates slip past each other - Such faults are generally moderate and are relatively shallow Example: The San Andreas Fault






36. 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

37. Officially defined as sustained sea surface temperature anomalies of magnitude greater than 0.5






38. 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






39. The sun is not at the center of the disk - but out toward the perimeter - and is revolving around the ________






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






41. Water transpired from plants and evaporated from the soil






42. Sun heats water in the oceans - Water evaporates as vapor into the air - Ice and snow can sublimate directly into water vapor...- Over time - the water reenters the ocean - where the water cycle started






43. Large - scale movements of the earth's lithosphere - - The theory encompasses the older concepts of continental drift (first half of 20th century) and seafloor spreading (1960s)






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