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. Center: 3000


2. 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






3. Formed by sodium chloride






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






5. Tides may be...






6. Water transpired from plants and evaporated from the soil






7. 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






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


9. 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)






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


11. 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






12. Somewhat cooler disturbances in the photosphere






13. Mountains blocking the path of precipitation to the desert






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






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






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






17. 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






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






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






20. Under solar conditions - gases are undergoing _____ to heavier elements with the increase of prodigious quantities of energy






21. Characterized by similar temperatures and moisture levels






22. Nearest galaxy - about 20 million light - years away






23. 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






24. Large - dark clouds that indicate thunderstorms






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






26. When the moon is at first quarter or third quarter - the sun - earth and moon form a 90- degree (right) angle with the earth at the vertex - The combined effect of this alignment of the sun - earth - and moon results in tidal ranges on the earth - Wh






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






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






29. Test the item against materials of known hardness; for example - use your fingernail or the graphite in a pencil to attempt to scratch the items. This process should result in assigning a relative hardness to the unknown items.






30. 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






31. A ______________ - such as the Mid - Atlantic Ridge - has examples of volcanoes caused by divergent tectonic plates pulling apart






32. The degrees north or south of the equator






33. Continental polar (dry - cold air)






34. 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






35. Featherlike clouds that indicate fair weather






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

38. Distance to closest stars can be calculated by measuring the _________ - a slight shift in apparent position against the background of more distant stars as the earth travels around the sun






39. 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






40. 1 hour of time






41. 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
