CSET Science: Geology

Subjects : cset, science, geology
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 highest layer of the atmosphere where the atmosphere is very thin






2. The process in which plates move and shift






3. Active boundary where tectonic plates meet






4. Solid and extremely hot layer of the mantle that protects the core






5. Fossil in which a part of the organism that has been preserved






6. Plate tectonic boundaries where the platse are moving toward each other with one plate eventually going under the other






7. Era from 2.5 billion to 570 million years ago when the continents formed and oxygen began. The first eukaryotic cells appear.






8. The act of using radioactive isotopes to date fossils






9. The fourth layer of the atmosphere - which is also the hottest because the air is so thin and the temperature is up to 2000 degrees Celsius






10. Rocks that form when molten rock cools and hardens either deep underground or on the surface






11. The period where the first fish were formed






12. The form that water returns to earth as - like rain - snow - sleet - and hail






13. The period when the first amphibians were born. Named after Devon - England where fossils were first discovered






14. Layer of atmosphere that is above the stratosphere where the coldest temperature is reached at minus 90 degrees






15. The different ways a species can evolve






16. Pieces of the Earth that make up its crust and float on top of the upper mantle






17. The study of rock layers and the fossils contained inside of them






18. Rocks that are made from bits and pieces of other rocks and dead animal and plants that have been pressed together over time






19. The look of a mineral when scratched upon a porcelein plate






20. Era from 570 to 245 million years ago with the explosion of animal diversity followed by the wiping out of 99 percent of planetary life thanks to an asteroid. Pangea rises.






21. The warming up of the Earth because of certain gases in the atmosphere






22. Seismic waves that are the slowest but most dangerous because they move on the surface and can knock buildings to the ground






23. Water that has infiltrated the ground






24. A volcano that is formed when ash and cinders are blown out of a single vent






25. Document produced by the seismograph that shows how long and how intense an earthquake was






26. Molten rock






27. The Earth's only liquid layer that is extremely hot and made out of iron and nickel






28. The lowest layer of the atmosphere. It is also known as the weather layer since snow - rain - and wind stick to this layer






29. Volcano that is formed at convergent boundaries of tectonic plates and the subducted plate melts into lava






30. Mountains made up by faults - a huge crack in rock where movememnt happens where tectonic plates pull apart






31. Mountains with sharp peaks and ridges caused when forces inside the earth push up parts of the crust






32. A harbor wave that occurs when there is a violent disturbance deep below the ocean - like an earthquake - which creates a wave that stores a huge amount of energy






33. The way that water returns to earth by flowing on the surface into streams - lakes - and rivers






34. A mixture of gas consisting of oxygen and nitrogen that wraps the earth like a blanket






35. Also known as secondary waves - these are the second - fastest seismic waves and they travel at right angles to the direction of the movement and they produce vertical and horizontal motion






36. Era from 3.8 to 2.5 biillion years ago with the beginning of the geologic record and the formation of the first forms of rocks and bacteria






37. Rocks made out of trapped magma that takes longer to cool beneath the surface






38. All plants and animals have to compete for food - water - space and the fear of being eaten






39. Also known as the center of the earth - it is made out of mostly iron






40. The limited supply of water there is






41. A fossil caused when the mold of the skeleton of a dead animal is filled with minerals from the bubbling water and the minerals take the shape of the skeleton






42. Volcano that occurs at divergent plates in underwater plates and creates lava from a mineral called basalt






43. Plate tectonic boundaries where plates sllide horizontally pass each other and cause friction






44. Areas of great heat and activity in the earth's mantle where shield volcanoes can form






45. The process in which water soaks into the ground






46. Thew ay a mineral breaks along its crystalline structure






47. The layer of the atmosphere that is 50 km above ground and is where the ozone layer is at






48. The part of the Earth that we live on






49. A layer of rock that contains fossils






50. The thick - spongy substance that was created when swamp planst decomposed 300 million years ago. With heat - it becomes coal
