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. The process of chemical or physical breakdown of earth rocks - soils - and their minerals






3. Oceans cover __ of the earth's surface






4. 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






5. Seas - gulfs - bays - and other names






6. Affected by factors such as weathering and impurities






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






8. Forms over water and is associated with wet air






9. Sometimes called minor planets or planetoids - Bodies

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






12. - The materials left over after the rock breaks down combine with organic material - The mineral content is determined by the parent material; thus - a soil derived from a single rock type can often be deficient in one or more minerals for good ferti






13. 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






14. 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






15. 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...






16. 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






17. Paleontology: Fossil evidence indicates the similarity of fossils on both sides of the Atlantic Ocean - Continental 'jigsaw puzzle': The outlines of the continents seem to fit together






18. Human civilization has lasted only _____ years






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






20. Occur along plate boundaries






21. Occurs at the instant when the sun's position in the sky is at its greatest angular distance on the other side of the equatorial plane from the observer's hemisphere - Depending on the shift of the calendar - the winter solstice occurs some time betw






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






23. Rocks are placed into groups according to how they form...






24. Thought to originate in the Kuiper Belt - or associated scattered discs - which lie beyond the orbit of Neptune






25. 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






26. 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






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






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






29. Texture is important in classifying ______ sedimentary rocks






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






31. A natural flow of water - usually freshwater - traveling toward an ocean - a lake - or another stream






32. Method of using the present to interpret the past - Processes occurring today are observed carefully and their effects are measured - Then - geologists assume that similar effects in ancient rocks were caused by processes similar to those of the pres






33. One tidal cycle per day






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






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