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 4.6 to 3.8 billion years ago when the Eaerth formed and the planet cooled off






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






3. The machine that is used to measure earthquakes






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






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






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






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






8. 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






9. Water that has infiltrated the ground






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






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






12. The process in which water soaks into the ground






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






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






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






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






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






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






19. Molten rock






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






21. The part of the Earth that we live on






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






23. Thew ay a mineral breaks along its crystalline structure






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






25. 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






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






27. The animal in which a species has evolved from to specialize in their environments






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






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






30. 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






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






32. The act of using radioactive isotopes to date fossils






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






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






35. The degree that a mineral reflects light






36. 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






37. The period where the first fish were formed






38. The crystals formed when igneous rocks cool underground






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






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






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






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






43. 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






44. 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






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






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






47. A layer of rock that contains fossils






48. The process in which plates move and shift






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






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