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. 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






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






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






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






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






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






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






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






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






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






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






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






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






14. 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






15. The period where the first fish were formed






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






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






18. The act of using radioactive isotopes to date fossils






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






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






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






23. The process in which water changes from liquid to gas






24. 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.






25. Changes that were made to the DNA and RNA






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






27. Active boundary where tectonic plates meet






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






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






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






31. The limited supply of water there is






32. The part of the Earth that we live on






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






34. Molten rock






35. 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






36. 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.






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






38. The process in which water soaks into the ground






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






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






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






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






43. Areas where oceanic earthquakes can occur when an ocean plate hits a continental plate and eventually goes underneath






44. 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






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






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






47. A layer of rock that contains fossils






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






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






50. The process in which plates move and shift
