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 machine that is used to measure earthquakes






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






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






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






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






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






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






8. The part of the Earth that we live on






9. 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






10. Degree to which a mnieral can be scratched






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






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






13. 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






14. 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






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






16. 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






17. The crystals formed when igneous rocks cool underground






18. The degree that a mineral reflects light






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






20. The different ways a species can evolve






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






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






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






24. 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






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






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






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






28. 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.






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






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






31. Also known as 'survival of the fittest -' the idea that the animal which is the most adjusted will survive long enough to reproduce and produce offspring that have the same types of qualities for their survival






32. Rocks that are formed through major changes like heat like plate movements and they cool down






33. Changes that were made to the DNA and RNA






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






35. The act of using radioactive isotopes to date fossils






36. The limited supply of water there is






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






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






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






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






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






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






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






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






45. 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






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






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






48. The process in which plates move and shift






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






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