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






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






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






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






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






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






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






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






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






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






11. Thew ay a mineral breaks along its crystalline structure






12. 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






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






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






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






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






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






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






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






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






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






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






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






24. 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






25. A layer of rock that contains fossils






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






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






28. 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.






29. The crystals formed when igneous rocks cool underground






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






31. The different ways a species can evolve






32. The act of using radioactive isotopes to date fossils






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






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






35. 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






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






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






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






39. Degree to which a mnieral can be scratched






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






41. Rocks that are made from bits and pieces of other rocks and dead animal and plants that have been pressed together over time






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






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






44. The part of the Earth that we live on






45. The process in which plates move and shift






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






47. 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






48. The process in which water soaks into the ground






49. The limited supply of water there is






50. 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
