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. Comprised of the crust and the rigid uppermost part of the mantle - broken up into tectonic plates (7 major and many minor) - ride on the asthenosphere






2. Continental polar (dry - cold air)






3. Seas - gulfs - bays - and other names






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






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






6. Gas giants Jupiter - Saturn - Uranus and Neptune have diameters far larger than Earth's and have far greater masses






7. 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






8. 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






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






10. Volcanoes can also form where there is stretching and thinning of the...


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






12. 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






13. Different visual appearance; when discovered - comets show a perceptible coma while asteroids do not






14. Can thaw and melt - and the ensuing water flows overland as snowmelt






15. Somewhat cooler disturbances in the photosphere






16. A land form that stretches above the surrounding land in a limited area - with a peak - Usually produced by the movement of lithospheric plates






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






18. 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






19. 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.






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






21. Occur when two plates push together - Such faults are strong and relatively deep - Where the strongest earthquakes occur Example: mountain building in the Himalayas and the Andes






22. 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






23. Formed by sodium chloride






24. Temperature - pressure - and composition






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






26. Condensed water vapor that falls to the earth's surface - Most precipitation occurs as rain - but also includes snow - hail - fog drip - graupel - and sleet






27. The result of the buildup of once - living things






28. 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






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






30. 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
