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






2. The degree that a mineral reflects light






3. 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






4. 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.






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






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






7. 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






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






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






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






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






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






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






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






16. The part of the Earth that we live on






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






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






19. 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






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






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






22. The different ways a species can evolve






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






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






25. The process in which water soaks into the ground






26. The process in which plates move and shift






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






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






29. 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






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






31. The act of using radioactive isotopes to date fossils






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






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






34. Water that has infiltrated the ground






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






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






37. Molten rock






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






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






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






41. 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






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






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






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






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






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






47. 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.






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






49. 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






50. Changes that were made to the DNA and RNA
