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. 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






2. The process in which one type of rock changes into another






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






4. One tidal cycle per day






5. 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...






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

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






17. Earth movements - The result of forces within the earth - where temperature and pressure differences lead to instability






18. Travels in an orbit that is slightly elliptical (oval) - and so the distance from the sun ranges from 91.5 to 94.5 million miles - Its daily rotation deforms the earth to a flattened spheroid - with a polar radius slightly less than the equatorial ra






19. 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






20. Mountains blocking the path of precipitation to the desert






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






22. 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






23. The movement of rainwater as it filters through soil and rocks into the ground - becoming groundwater






24. Younger beds were originally deposited above older beds






25. A major determiner of coastal climate






26. 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






27. 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






28. Both gravity and inertia work together to keep planets in orbit around the sun - Inertia makes a planet travel in a straight line






29. Huge systems of stars - Milky Way is estimated to have 100 billion stars arranged in a great disk






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