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






2. A layer of rock that contains fossils






3. Thew ay a mineral breaks along its crystalline structure






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






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






6. 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






7. Molten rock






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






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






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






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






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






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






14. The crystals formed when igneous rocks cool underground






15. 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.






16. The process in which water soaks into the ground






17. Changes that were made to the DNA and RNA






18. 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






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






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






21. The act of using radioactive isotopes to date fossils






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






23. The limited supply of water there is






24. Active boundary where tectonic plates meet






25. 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






26. The degree that a mineral reflects light






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






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






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






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






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






32. 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






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






34. The Earth's rivers - lakes - and oceans






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






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






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






38. Water that has infiltrated the ground






39. The different ways a species can evolve






40. The part of the Earth that we live on






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






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






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






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






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






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






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






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






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






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