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 period where the first fish were formed






2. The process in which plates move and shift






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






4. Water that has infiltrated the ground






5. The crystals formed when igneous rocks cool underground






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






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






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






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






10. The machine that is used to measure earthquakes






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






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






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






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






15. A natural disaster caused by pressure deep within the Earth that splits the ground






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






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






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






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






20. The act of using radioactive isotopes to date fossils






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






22. Molten rock






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






24. The limited supply of water there is






25. 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






26. 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






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






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






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






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






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






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. Era between 245 to 65 million years ago and known as the Age of the Reptiles because this was whe nthe dinosaurs existed until a mass extinction. Pangea separates.






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






35. 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.






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






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






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






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






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






41. Active boundary where tectonic plates meet






42. A layer of rock that contains fossils






43. 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






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






45. A basic type of landform that produces water - forms wind barriers






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






47. Time scale that scientists use to break up the historical changes on the Earth into eons - eras - periods - and epochs






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






49. 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






50. Degree to which a mnieral can be scratched
