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 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






2. Molten rock






3. A gas that absorbs harmful UV rays and protects us from too much radiation






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






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






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






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






8. A giant range of stratovolcanoes that circle the Pacific Ocean






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






10. Active boundary where tectonic plates meet






11. The machine that is used to measure earthquakes






12. Also known as primary waves - these are the fastest seismic waves and the first to be detected. They compress and expand both liquid and solid rock as they move through it






13. Water that has infiltrated the ground






14. Thew ay a mineral breaks along its crystalline structure






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






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






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






18. Organisms - like plants - that take more carbon out of the atmosphere than put into it






19. The mountain ranges taht is a result of when two tectonic plates collided with each other






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






21. A fossil that is caused when the skeleton of a dead animal or plant is covered in sand and water and rock and decays over time - leaving a hollow print of the skeleton






22. Era from 4.6 to 3.8 billion years ago when the Eaerth formed and the planet cooled off






23. Fossil in which an animal's tracks - poop - nests - and bite marks have been preserved






24. The crystals formed when igneous rocks cool underground






25. Mountains created when hot molten rock pushes up from the earth's mantle






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






27. The highest layer of the atmosphere where the atmosphere is very thin






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






29. Remnant of an organism. They are found underground and are at least several thousands years old






30. The degree that a mineral reflects light






31. 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






32. Earth layer made up of silicon - iron - magnesium - and oxygen and makes up most of the Earth's mass






33. 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.






34. Changes that were made to the DNA and RNA






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






36. The limited supply of water there is






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






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






39. Modern era from 65 million years ago to now and known as the Age of the Mammals because of the birth of humans






40. Tectonic plate boundaries where plates are moving apart and new crust is being formed by rock pushed up in the mantle






41. The process in which water soaks into the ground






42. A layer of rock that contains fossils






43. 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






44. The mega continent that was once a combination of all the world's continents millions of years ago






45. Soft and plastic layer of the mantle that allows plate tectonics to move






46. Changes to genetic code that become permanent and can be bad - like sickle cell anemia and cancer






47. 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






48. The act of using radioactive isotopes to date fossils






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






50. Degree to which a mnieral can be scratched
